Fig. 2 show a kind of detailed description of the invention according to the present invention for manufacturing combined orthodontic system The method of system.Owing in the ordinary course of things, combined orthodontic system is often by representing a series of orthodontics A series of dental appliances composition of state, and corresponding to the first orthodontic stage and the second orthodontic stage The first dental appliance of orthodontic state and the second dental appliance be generally contained within a series of tooth and rectify Control among device.So Fig. 2 represents a series of tooth with comprise the first dental appliance and the second dental appliance Rescue as a example by the combined orthodontic system that a series of dental appliances of state are formed in the present invention Certain detailed description of the invention illustrates.But the combined orthodontic system described in the present invention is not limited to by table Show a series of dental appliances composition of a series of orthodontic state.

First, in step S101, obtain and include that rescuing the stage and second corresponding to first rescues the tooth in stage Tooth rescues the first tooth digitized data model of state and the second tooth digitized data model in interior expression one is A series of tooth digitized data models of row orthodontic state.Here, " a series of orthodontic state is represented A series of tooth digitized data models " refer to the computer digital data mould for instructing tooth model to manufacture Type, obtained tooth model is the threedimensional model of dental phenomenon (alternatively referred to as tooth arrangement).Described tooth The state of rescuing includes a series of revised dental phenomenon, and the corresponding tooth numerical data of each dental phenomenon Model.Each dental phenomenon include the geometry corresponding to some the teeth rescuing step and tooth it Between position relationship, therefore each corresponding tooth digitized data model includes the geometry representing some teeth Shape and the digital data sets of interdental position relationship.

In an exemplary specific embodiment, first according to the current dental phenomenon of patient or tooth and The state of its perienchyma (such as gingiva, facial soft tissue) makes physical tooth model (such as by impression taking Make Gypsum Fibrosum tooth model), then this physical tooth model is scanned, represent the former of patient teeth to generate The virtual tooth model (corresponding to basis dental phenomenon) of beginning state.Certainly, it is possible to by optical scanning, three Dimension photograph, three-dimensional camera shooting or Medical CT scanning directly obtain the image of tooth or tooth and perienchyma thereof, By computer disposal to generate original virtual tooth model.This virtual tooth model can be by digitized Reason and display.

Rescue target it follows that based on this original virtual tooth model and patient teeth, set at least one Rescue parameter, computer system rescue according to this original virtual tooth model and set at least one Parameter automatically form the most progressive a series of orthodontic state (alternatively referred to as expectation dental phenomenon or Tooth arrangement model after rescuing).Described a series of orthodontic state reflects to enter original tooth model Row is a series of rescue after step to tooth structure or the favourable change of arrangement.Process is rescued it is said that in general, whole Rescuing step (such as include 20-40 rescue step) including at least one, it is corresponding that each rescues step In an orthodontic state, and the corresponding tooth digitized data model of each orthodontic state, therefore Can be obtained and store a series of tooth digitized data model by computer system.

Further, the present invention is not limited to based on original virtual tooth model and rescues target and progressively produce and represent tooth The target of tooth rescues the method for state, it is also possible to by other method, such as by first determining the original shape of tooth The digitized data model of state and the digitized data model representing tooth final state, by computer system based on tooth The digitized data model of initial condition and final state produces the numeral of a series of dental phenomenons in the middle of representing The method of data model obtains the digitized data model of the representative orthodontic state in the present invention.

It follows that in step s 102, at a series of tooth numeral numbers representing a series of orthodontic states According in model, determining that at least one rescues the diacritical point in stage, the first tooth digitized data model is positioned at rescues rank Before section diacritical point, and the second tooth digitized data model is positioned at after rescuing stage diacritical point.

According to a kind of detailed description of the invention of the present invention, the health status of tooth accommodated in conjunction with patient, wrong jaw The situations such as deformity type, the oral healthy condition of patient, age, sex and pain sensitivity determine institute State the diacritical point in the stage of rescuing.As described in step S101, computer system is according to original virtual tooth mould Type etc. automatically form the most progressive a series of orthodontic state (alternatively referred to as expectation dental phenomenon or Tooth arrangement model after rescuing).Described a series of orthodontic state reflects to enter original tooth model Row is a series of rescue after step to tooth structure or the favourable change of arrangement.Process is rescued it is said that in general, whole Step (such as include 20-40 rescue step) is rescued including at least one.Rescue it is to say, whole Process at least includes the initial stage of rescuing and rescues the later stage, owing to patient is different for the adaptedness of dental appliance, Rescue the initial stage and rescue that the later stage is suitable for rescue intensity and different types of malocclusion type and difference Intensity of rescuing required for patient also differs.It is therefore desirable to determine and rescue initial stage and later stage for differentiation Stage of rescuing diacritical point, further, it is possible to combine the health status of the tooth that patient is accommodated, malocclusion Type, the oral healthy condition of patient, age, sex and pain sensitivity, be determined for compliance with personalized need Stage of the rescuing diacritical point asked.

The type of tooth malocclusion determines that the important references factor rescuing stage diacritical point.In specific implementation process In, it is necessary first to the malocclusion type of patient is judged.The most most widely used one Malocclusion sorting technique is iS-One malocclusion sorting technique, and it is big that malocclusion has been largely divided into three by the method Class.Class is neutral wrong jaw, and on this kind of wrong jaw, the middle relation near, remote of mandibular bone and dental arch is normal, i.e. when just During middle conjunction position, the near middle cheek point of upper sixth-year molar is snapped in the mesiobuccal groove of lower sixth-year molar.If full mouth None dislocation person of tooth, referred to as normal occlusion；If the person of having dislocation, the most referred to as I class mistake jaw.I class mistake jaw master Crowding anterior teeth to be shown as, upper dental arch prolapse, bimaxillary, underbite of anterior teeth and backteeth cheek, linguoversion etc.. Equations of The Second Kind mistake jaw is middle wrong jaw, and this wrong jaw lower dental arch and lower jaw are in remote middle position.If lower jaw retreats 1/4 Individual grind one's teeth in sleep or the distance of half premolars, sixth-year molar i.e. up and down near in cheek point relatively time, be referred to as slight remote Middle wrong jaw relation.If lower jaw retreats again, to such an extent as to the near middle cheek point of upper sixth-year molar is snapped at down the first permanent mill Tooth and the second premolars, then be remote completely in wrong jaw relation.In remote, wrong jaw the most also can be divided into To tilting and the Linguoclination of maxillary incior, in any one inclination conditions, all there is side remote in the lip of jaw incisor Middle wrong jaw, his side is the situation of neutral conjunction relation.Include deeply covering with the symptom of class ii mistake jaw relation, Deeply covering jaw, upper lip deficiency of development and X-ray cephalometry, introversion moldeed depth covers jaw etc..Group iii mistake jaw is near middle wrong Jaw, under this kind of wrong jaw relation, lower dental arch and lower jaw are in nearly middle position.If mandible go forward 1/4 is ground one's teeth in sleep or half The distance of premolars, the far middle cheek point of the near middle sharp and lower sixth-year molar of cheek i.e. going up sixth-year molar is relative, is referred to as Slight near middle wrong jaw relation.If lower jaw is ground one's teeth in sleep or the distance of 1 premolars to mesiogression 1/2, so that In maxillary first molars near in cheek point be engaged in down between first, second accessional teeth, then be completely closely in Wrong jaw relation.In 3rd class mistake jaw relation, equally exist unilateral nearly middle wrong jaw, and his side is neutral conjunction relation Situation.In the detailed description of the invention of the present invention, according to wrong jaw relation and the wrong jaw journey of different malocclusion types Degree determines rescues stage diacritical point.

And the judgement of the malocclusion type for patient, need to use oral and maxillofacial surgery armarium to set as diagnosis Standby.The most conventional oral and maxillofacial surgery medical imaging equipment includes: dental sheet machine, surface fault machine, x-ray head Shadow measuring machine, oral cavity body cavity X-ray machine, oral cavity 3D-CT machine etc..In the particular embodiment, first pass through Oral and maxillofacial surgery medical imaging equipment carries out imaging of medical to oral and maxillofacial surgery, the tool obtained in conjunction with step S101 The tooth digitized data model of body determines the concrete wrong jaw type of patient and feature.Representing orthodontic state A series of tooth digitized data models determine that at least one rescues stage diacritical point, uses not before and after diacritical point Same elastic modelling quantity, the appliance diaphragm of different-thickness make the dental appliance that this step is corresponding, thus improve tooth The multidimensional that tooth moves controls and system effectiveness.

In an exemplary specific embodiment, utilize oral cavity 3D-CT machine Mouthsimulator whole scenery piece and head Lateral projection.According to the image obtained by the 3D-CT machine of oral cavity and in S101 step obtain a series of tooth of expression Tooth rescues a series of tooth digitized data models of state, determines the wrong jaw class of patient according to iS-One mistake jaw classification method Type belongs to neutral wrong jaw, middle wrong jaw or nearly middle mistake jaw, and concrete wrong jaw degree belongs to slight mistake jaw the most completely Wrong jaw, and whether there is the situation of unilateral wrong jaw.According to the analysis result of malocclusion type, representing tooth Tooth is rescued and is determined in a series of tooth digitized data models of state and one or more rescue stage diacritical point so that Obtained rescue stage diacritical point before the first dental appliance with rescue second after stage diacritical point The elasticity of the housing of dental appliance differs, thus realizes according to different wrong jaw Type Control orthodontics Efficiency and level of comfort.

Concrete, in the case of slight or neutral wrong jaw, selected concrete stage of rescuing diacritical point, making During dental appliance so that rescue the elasticity of the first dental appliance before stage diacritical point more than rectifying Control the elasticity of the second dental appliance after stage diacritical point.So that patient has worn rescues stage diacritical point During the first dental appliance before, the Orthodontic force suffered by tooth is relatively small, is reaching identical treatment mesh On the premise of mark, it is more excellent that entirety rescues comfort level.And in the case of the serious malocclusions such as the most wrong jaw, choosing The most concrete fixed stage of rescuing diacritical point, during manufacturing dental appliance so that rescue stage diacritical point it After the elasticity of housing (the i.e. second housing) of the second dental appliance more than rescuing the before stage diacritical point The elasticity of the housing (the i.e. second housing) of one dental appliance, thus improve the efficiency that tooth moves, finally reach Effect is moved to preferable tooth.

In some specific embodiments, S102 is also added into sub-step S1021, patient is carried out pain quick Sensitometry, the pain sensitivity on ordinary meaning includes pain threshold and tolerable pain threshold value.According to testing To pain threshold and tolerable pain threshold value and obtain before this represent a series of orthodontic states one be Row tooth digitized data model, determines one or more diacritical point rescuing the stage, each rescues stage diacritical point The elasticity of dental appliance housing front and back differs.

The most conventional pain sensitivity assay method includes: mechanical stimulus method, warm stimulus method, cold water stimulating Method, electrostimulation, Writhing test and Esmarch's bandage pain determining method etc..Wherein, mechanical stimulus method is by right The osseous tissue pressure of patient, so as to judging pain degree.Warm stimulus method is that gathering light is shifted near skin, note Record patient feels heat during pain.Cold water stimulating method is to immerse in cold water by the forearm of testee, record pain Time of occurrence bitterly.Electrostimulation, the increase exported by electric current, current intensity during record patient feels pain. Chemical stimulation rule is to make epidermis produce herpes with cantharidin plaster, acts on bottom herpes with algogenic substance, uses To measure pain threshold.Esmarch's bandage pain determining is to drive blood at forearm Esmarch's bandage, with the time that patient stands is Pain threshold.

In a specific embodiment, use electrostimulation to carry out pain sensitivity mensuration, specifically, hold Continuous increase electric current, when patient feels pain, recording this current value is pain threshold.Continue to increase electric current, When patient feel be difficult to bear the pain time, recording this current value is that pain restrains oneself threshold value.By measured pain Threshold value and pain are restrained oneself threshold value and are compared with the current threshold table formulated in advance, if the pain sensitivity of patient Higher than average, it is determined that a diacritical point rescuing the stage so that the first tooth before this diacritical point is rectified The elasticity of the housing controlling device is more than the elasticity of the housing of the second dental appliance after diacritical point, thus relatively reduced The size rescuing step Tooth appliance correcting action power before rescuing diacritical point, ease the pain sense, improves Rescue the comfort level of process.

Although it should be noted that the mensuration side describing pain sensitivity in the present invention as a example by electrostimulation Method, but the pain sensitivity measuring method of the present invention is not limited to electrostimulation, but other can be used to ache Sensitivity assay method bitterly measures the pain sensitivity of patient.

After recording patient pain's sensitivity situation, in a particular embodiment, can be in conjunction with malocclusion class Type and a series of tooth digitized data models of a series of orthodontic states of expression, determine one or more rescuing Stage diacritical point, and determine the integral, flexible size of this combined orthodontic system Tooth appliance.Certainly, Can also be according to malocclusion type and a series of tooth numerical data moulds representing a series of orthodontic states Type first determines one or more rescues stage diacritical point and this combined orthodontic system Tooth appliance Integral, flexible.In conjunction with the oral cavity pain sensitivity state of patient, to rescuing stage diacritical point position and tooth The integral, flexible rescuing system Tooth appliance is modified.

In some detailed description of the invention, the elasticity of the first housing before rescuing stage diacritical point is better than rescues rank The elasticity of the second housing after section diacritical point.For the patient that pain sensitivity is higher, compared to pain sensitivity Relatively low patient, determines when it rescues the position of stage diacritical point, it should select relatively rearward position.From It is and it is longer to make patient wear time of elastic preferably dental appliance, the least to the Orthodontic force of tooth, Comfort is the strongest, such that it is able to alleviate the pain of dental appliance.

In some specific embodiment, the elasticity of the first housing before rescuing stage diacritical point is better than to be rescued The elasticity of the second housing after stage diacritical point.For suffering from the patient of serious periodontal, compared to not having The patient of periodontal, determines that it should select relative rearward position when rescuing stage diacritical point position.Thus Patient is made to wear time of elastic preferably dental appliance longer.Elasticity is the best, the Orthodontic force phase to tooth To the least, comfort is the strongest, such that it is able to alleviate dental appliance the injury at the injury of oral cavity, elimination are had mouth The patient of chamber disease is issuable sense of discomfort during using dental appliance.

In some specific embodiment, determining the whole of this combined orthodontic system Tooth appliance During body elasticity, for suffering from the patient of serious periodontal, compared to the patient not having periodontal.Selected The integral, flexible of combined orthodontic system Tooth appliance bigger.Thus improve the comfortable of entirety Sense, alleviates the impact on affected part.

The elasticity of dental appliance is relevant with many factors, the thickness of the housing of such as dental appliance, material Elastic modelling quantity, the method for post processing and adnexa facilities etc..In certain embodiments, tight for suffering from The patient of weight periodontal, the integral thickness of the combined orthodontic system Tooth appliance of selection is thinner. In further embodiments, for suffering from the patient of serious periodontal, the combined orthodontic system of selection The elastic modelling quantity of the material of the housing of Tooth appliance is less.In other specific embodiment, for suffering from The patient of serious periodontal, all dental appliances in combined orthodontic system all through post processing, The integral, flexible making all dental appliances improves.In other specific embodiments, for suffering from serious tooth The patient of all diseases, all dental appliances in combined orthodontic system all comprise adnexa so that all The integral, flexible of dental appliance improves.

It should be noted that and the present invention rescues stage diacritical point with this combined tooth system integral, flexible really The Consideration of timing is not limited only to the oral healthy condition of malocclusion type and patient, and pain Sensitivity.Also should include the health status of tooth, age, sex and demands of individuals etc. that patient is accommodated All of individual demand, thus realize targetedly tooth moving efficiency, move mode and moving easypro The various dimensions of appropriateness control.

According to a kind of detailed description of the invention of the present invention, the health status of the tooth that comprehensive patient is accommodated, wrong jaw Deformity type, the oral healthy condition of patient, age, sex, pain sensitivity and represent a series of tooth The a series of tooth digitized data models rescuing state determine that is rescued a stage diacritical point.First dental appliance For rescuing the dental appliance corresponding to the tooth digitized data model before stage diacritical point, the second orthodontic Device be rescue stage diacritical point after the second orthodontic corresponding to tooth digitized data model rescuing the stage Device, wherein, the elasticity of the housing of the first dental appliance is more than the housing of the second dental appliance.

In other specific embodiments, the health status of tooth that accommodated in conjunction with patient, malocclusion Type, the oral healthy condition of patient, age, sex, pain sensitivity and represent a series of orthodontic A series of tooth digitized data models of state determine that two are rescued stage diacritical point.Wherein, the first orthodontic Device be first rescue stage diacritical point before the first tooth corresponding to tooth digitized data model rescuing the stage Tooth appliance, the second dental appliance be first rescue stage diacritical point after second rescue stage diacritical point before The second dental appliance corresponding to tooth digitized data model rescuing the stage, the 3rd dental appliance is Two rescue stage diacritical point after the 3rd orthodontic corresponding to tooth digitized data model rescuing the stage Device.Wherein, the elasticity of the housing of the first dental appliance, the second dental appliance and the 3rd dental appliance is not Identical, in other specific embodiments, the housing of the first dental appliance and the 3rd dental appliance Elastic identical.

It should be noted that the first dental appliance is all of strong before both can correspond to rescue stage diacritical point Control step, the step of certain or certain several correspondences before rescuing stage diacritical point can also be simply corresponded to equally Suddenly.In the another kind of specific embodiment of the present invention, according to the initial condition of patient teeth with rescue target, Finally determine and have 20 and rescue step, in step S101, obtain and rescue corresponding to described 20 20 tooth digitized data models of step.The health status of the tooth accommodated in conjunction with patient, wrong jaw are abnormal Shape type, the oral healthy condition of patient, age, sex, pain sensitivity, determine that is rescued a stage district Branch, wherein belongs to first corresponding to the 6th to the 9th tooth digitized data model rescuing step and rescues the stage, And belong to second corresponding to the 14th tooth digitized data model rescuing step and rescue the stage, rescue according to first Stage and second rescues the tooth digitized data model in stage and makes the first dental appliance and the second orthodontic Device so that the elasticity of the first dental appliance is more than the elasticity of the second dental appliance.

After it should be noted that step S102 is not necessarily located at step S101 step.In practice, step Before rapid S102 is also possible to be positioned at step S101 step.Such as, doctor can be according to the malocclusion of patient Type, oral healthy condition and pain sensitivity first determine specifically rescues stage diacritical point.When according to step When S101 generates a series of tooth digitized data model representing a series of orthodontic states, further according to before this Stage of the rescuing diacritical point determined is to should determine that corresponding tooth digitized data model accurately.

It follows that in step s 103, tooth model (the i.e. tooth of physics is generated according to tooth data model The formpiston of appliance).I.e. according to a tooth digitized data model system of a series of tooth digitized data model Make a corresponding physical tooth model.

Preferably, the formpiston of dental appliance is manufactured based on rapid shaping process.Rapid shaping technique can be divided into The most several typical forming technologies: laser fast forming (Stereo lithography Apparatus, SLA), Layer separated growth (Laminated Object Manufacturing, LOM), selective laser sintering (Selected Laser Sintering, SLS), Fused Deposition Modeling (Fused Deposition Modeling, FDM), three-dimensional Print and manufacture (Three Dimensional Printing, 3DP) etc..On moulding material, the most organic Macromolecular material, such as light-cured resin, nylon, wax etc..Wherein laser fast forming SLA is to use to swash Light pointwise illumination light-cured resin, induced material generation chemical change thus the method that solidifies shape, and is layered reality It is then to use cut foil (paper, ceramic foil, metal forming etc.), by heat between foil that body manufactures LOM Melten gel realizes bonding under the pressure and heat transfer effect of hot-rolling, superposition forming from level to level；Selective laser sintering SLS is to use laser pointwise illumination dusty material that material powder is melted, or makes to be coated on outside dusty material Solid adhesive melt and realize the connection of material and shape, and Fused Deposition Modeling FDM is by thermoplastic forming Material adds heat fusing wherein after being continually fed into shower nozzle and sprays, progressively stack shaping.3 D-printing manufactures SDP is to use the method injection melted material stack shaping of similar inkjet printing or pointwise sprinkling bonding agent bonding The method of dusty material shapes.

In a specific embodiment, SLA method is used to manufacture tooth model, specifically, in order to manufacture Tooth model, based on the polyreaction of photosensitive resin, laser under the control of the computer, along tooth mould Type is respectively layered cross section profile, and liquid resin is carried out point by point scanning, makes the thin resin layer being scanned produce polymerization anti- Should, point gradually form line, ultimately form the solidification cross section of a thin layer of tooth model, and be not scanned Resin keep original liquid.When one layer of solidification is complete, and self-powered platform moves the distance of a synusia thickness, The resin surface having cured at last layer covers one layer of new liquid resin again, in order to carry out scanning again Solidification.One layer of new solidification is firmly bonded in preceding layer, so moves in circles, until whole tooth model Manufacture complete.Typically, mechanical blades inswept photosensitive resin surface is used, it is ensured that next layer is smooth resin bed. After tooth model shapes, self-powered platform promotes and tooth model removes from equipment.Typically, this is preliminary Tooth model clean in solvent such as acetone subsequently, this solvent dissolves uncured liquid resin and will not be molten The solid state medium that solution has cured.It is placed under high-intensity ultraviolet irradiation with back part, to complete solidification process, Thus obtain tooth model, i.e. for manufacturing the positive model of dental appliance or claiming formpiston.

Although it should be noted that in the present invention and describing the present invention as a example by laser fast forming SLA method Rapid shaping process step, but the present invention is not limited solely to laser fast forming SLA method, but Other quick molding method can be applied to manufacture tooth model.

After forming tooth model (formpiston) by speed forming method, in step S104, can be based on described tooth The formpiston of tooth appliance manufactures dental appliance.

In a kind of detailed description of the invention, by hot-embossing equipment, by malleation press mold technology, will be by transparent The appliance diaphragm that polymeric material (having resilient polymer, such as Merlon) is constituted is at above-mentioned tooth Suppress on model, to form housing, thus prepare dental appliance.But the present invention based on tooth mould Type manufactures the method for appliance and is not limited to hot-forming, it is also possible to utilize additive method, comes based on tooth mould Type manufactures dental appliance.

According to prior art, based on a series of teeth manufactured by tooth model (i.e. the formpiston of dental appliance) The diaphragm of same thickness and elastic modelling quantity of appliance or employing, or be only rescue step corresponding to one In the manufacture of the dental appliance that rapid shape is identical, have employed the diaphragm that thickness is different or elastic modelling quantity is different.

But according to the present invention, according to the number of stage of the rescuing diacritical point determined, step S104 can include Plural manufacture dental appliance sub-step, the diaphragm that each step manufacturing dental appliance is used Thickness or elastic modelling quantity differ.Now only to determine that is rescued a stage diacritical point, step S104 includes Illustrate as a example by two sub-steps manufacturing dental appliance.

As example, step S104 includes sub-step S1041 and S1042 (not shown).Wherein, exist In step S1041, according to based on the tooth model rescued before stage diacritical point, utilize the first high-molecular diaphragm Manufacture the first dental appliance.

Then, in step S1042, based on the tooth model rescued after stage diacritical point, utilize the second height Molecule diaphragm manufactures the second dental appliance.Wherein, the second high-molecular diaphragm can be and the first high-molecular diaphragm The diaphragm of same type can also be different types of diaphragm, described in detail below.

It is known that the Orthodontic force of invisalign technology is not only relevant with the geometry of the inner chamber of appliance, also Relevant with other factors.Therefore, can be by selecting the different thickness of the first high-molecular diaphragm and the second high-molecular diaphragm Degree, material, carry out different post processings or different adnexa facilities makes above-mentioned first dental appliance and the The elasticity (the i.e. first housing and the elasticity of the second housing) of the housing of two dental appliances differs, individually below List thickness, material, post processing and adnexa facilities for the coefficient of elasticity of dental appliance and to rescue The impact of power.

It is however noted that, although determine one with step S102 and rescue stage diacritical point, S104 bag Include two sub-steps thus distinguish with the formpiston rescued after stage diacritical point according to before rescuing stage diacritical point It is illustrated as a example by using two different diaphragm compacting appliances, however, it will be apparent that the invention is not restricted to this, According to the present invention, step S102 may determine that more than one rescues stage diacritical point, and therefore step S104 may be used To include two or more sub-step, such that it is able to according to each rescue stage diacritical point before and rescue the stage distinguish Formpiston after Dian uses the different diaphragms compacting dental appliance of more than two.So while hereafter with according to one Individual rescue stage diacritical point before and rescue the formpiston after stage diacritical point, use two different diaphragms compacting teeth It is illustrated as a example by tooth appliance, but its know-why, technical scheme and technical characteristic are equally applicable to root According to determining the plural formpiston rescuing stage diacritical point, use more than two (such as three sections, four sections) Diaphragm suppress appliance respectively, be not repeated at this.

A, utilize different-thickness diaphragm manufacture to rescue stage diacritical point before and after dental appliance

First, the diaphragm of different-thickness has different coefficient of elasticity and stress.Such as, when using Biolon Diaphragm (Germany produce), when thickness respectively 1.0mm, 0.75mm, 0.5mm carry out Experiments of Machanics it is found that Thickness is elastic modelling quantity and the maximum stress maximum of the diaphragm of 1.0mm, and the bullet of the diaphragm that thickness is 0.5mm Property modulus and maximum stress minimum.Therefore, the mechanical property of material changes along with the change of material thickness, Material is the thickest, and its elastic modelling quantity and maximum stress are the biggest, and material is the thinnest, and its elastic modelling quantity and maximum stress are the least. The diaphragm of other brands or material also has above-mentioned characteristic, is not repeated at this.

Therefore, in a kind of detailed description of the invention, in order to reach preferable rectifying effect, suitable thickness can be selected Degree material manufacture respectively in a series of dental appliance rescue stage diacritical point before and rescue stage district Dental appliance after branch.Diaphragm is the thinnest, then housing elasticity is the biggest, and patient wears the used time at the beginning and can compare Comfortable, and its stress (Orthodontic force) is less so that movement rate and the quantity of motion of tooth are less, thus suitable Share the appliance making previous utilization.And diaphragm is the thickest, then housing elasticity is the least, but its Orthodontic force is relatively Greatly so that the movement rate of tooth and quantity of motion are relatively big, so the appliance used after being adapted to be produced on, The Orthodontic force making the later stage can strengthen.

That is, in step S1041, based on the tooth model rescued before stage diacritical point, relatively thin is utilized One high-molecular diaphragm manufactures first group of dental appliance, and described first dental appliance is included in first group of tooth and rectifys Control in device, then, in step S1042, be again based on rescuing the tooth model after stage diacritical point, profit Manufacturing second group of dental appliance with the second thicker high-molecular diaphragm, described second dental appliance is contained in In two groups of dental appliances.

For a kind of combined orthodontic system, in order to obtain good rescuing comfort level and improve Rescuing efficiency, the thickness of the first dental appliance and the thickness of the second dental appliance should close in fixed proportion System, in certain embodiments, the thickness of described first dental appliance diaphragm is the second dental appliance The 70% to 95% of thickness, it is preferred that the thickness of the first dental appliance diaphragm is the second dental appliance film The 70% to 90% of the thickness of sheet.According to a kind of detailed description of the invention of the present invention, such as, in step S1041 In, based on rescuing tooth model before stage diacritical point, utilize first high-molecular diaphragm of 0.5 to 0.65mm Manufacture first group of dental appliance, wherein comprise the first dental appliance.Then, in step S1042, base Tooth model after rescuing stage diacritical point, utilizes the second high-molecular diaphragm manufacture of 0.70 to 0.80mm Second group of dental appliance, wherein comprises the second dental appliance.

It is of course also possible to determine and plural rescue stage diacritical point.Another kind according to the present invention is exemplary Embodiment, step S102 determines two diacritical points rescuing the stage, step S104 thus include three systems Make the sub-step of dental appliance.Such as, in step S1041, before rescuing stage diacritical point based on first Tooth model, utilize first high-molecular diaphragm of 0.5 to 0.65mm to manufacture first group of dental appliance, its Include the first dental appliance.Then, in step S1042, after rescuing stage diacritical point based on first Second rescues the tooth model before stage diacritical point, utilizes second high-molecular diaphragm of 0.70 to 0.80mm Manufacture second group of dental appliance, including the second dental appliance.Finally, in step S1043, base Rescue the tooth model after stage diacritical point in second, utilize the 3rd high-molecular diaphragm system of 0.85 to 0.9mm Make the 3rd dental appliance, including the 3rd dental appliance.

B, utilize the diaphragm manufacture of different materials to rescue stage diacritical point before and after dental appliance

For in theory, the thermoplasticity polymolecular material with biocompatibility can be used to manufacture invisalign Device.Such as, Merlon (PC) is a kind of water white indefiniteness thermoplastic, its water white transparency, Heat-resisting, shock resistance, fire-retardant, in commonly used temperature, there is good mechanical performance.And, processing characteristics Good, therefore it is a kind of common materials for manufacturing invisible orthotic device.

Further, constantly appliance is prepared possible with new material.Such as, polyether-ether-ketone (PEEK) Belonging to PAEK (PAEK) race with PEKK (PEKK), this race is to include ketone and ether merit The newest a series of high temperature resistant, nontoxic, the preferable polymer of thermoplasticity of energy group.Such as PEEK tree Fat also can stand the circulation autoclaving of up to 3000 times at 134 DEG C, and this characteristic makes it can be used for producing Sterilizing requires high, to need Reusability operation and dental equipment.PEEK not only has light weight, nontoxic, resistance to The advantages such as corrosion, or the current and immediate material of skeleton, can organically combine with human body, so using It is its another important application at medical field that PEEK resin replaces metal to manufacture skeleton.Additionally, PEEK Being readily extruded and molding is hit in injection, processing characteristics is excellent, and shaping efficiency is higher.

And PEKK is the height that the repetitive containing two ketonic bonds and an ehter bond in backbone structure is constituted Polymers, belongs to speciality polymer material, and it has the good characteristic of PAEK adoption compound equally.

Further, the application future of polyformaldehyde (POM) is the biggest.It is also referred to as acetal resin, is drawn Enter the most traditional polymethyl methacrylate.It has the proportional limit that a comparison is high so that it is elasticity It is demonstrated by a sufficiently large scope.

Therefore, the submission of the application at that time or will the most likely find multiple applicable manufacture invisible orthotic device future Material.Wherein elastic modelling quantity and the deformational stress of every kind of material are the most variant.Such as, when with PEEK, PEKK And POM is experimental subject, compare the these three material of same thickness time the Orthodontic force of tooth is affected, It appeared that PEEK has the highest elastic modelling quantity, thus tooth had maximum Orthodontic force.Next to that PEKK And POM.Therefore different materials has different character, thus when it is used for preparing appliance, is produced Orthodontic force the most different.

In a kind of detailed description of the invention, in order to reach preferable rectifying effect, can based on a determination that one with On the tooth model of stage of rescuing diacritical point, the diaphragm material selecting two or more elastic modelling quantity different is distinguished Manufacture appliance.The elastic modelling quantity of diaphragm material is the least, then elasticity is the best, and patient wears the used time at the beginning and can compare Comfortable, and its deformational stress (Orthodontic force) is less so that and movement rate and the quantity of motion of tooth are less, institute To be adapted to make the appliance of previous utilization.And the elastic modelling quantity of diaphragm material is the biggest, then elasticity is the poorest, But its stress is bigger so that the movement rate of tooth and quantity of motion are relatively big, so making after being adapted to be produced on Appliance so that the Orthodontic force in later stage can strengthen.

It is noted herein that, material behavior herein not only includes that raw material is because of its component or brand The original material characteristic caused, also includes the material behavior day after tomorrow caused because of pretreatment.Such as, same The diaphragm of the same thickness of brand is after artificial saliva soaks two weeks, and its maximum stress and elastic modelling quantity are the most Raising, cause which creating the material behavior day after tomorrow, therefore when it is used for suppressing appliance, prepared rescues Device is just provided with and utilizes the different material behavior of appliance that untreated diaphragm is suppressed, and this type of is because of pretreatment And the material behavior day after tomorrow caused belongs to the material behavior represented by the present invention.

C, increase last handling process rescue the dental appliance before and after stage diacritical point with manufacture

Diaphragm or the various pretreatment of invisible orthotic device or post processing (being referred to as " post processing ") can be led Cause its resilience force and produce change.Therefore, it can diaphragm or invisible orthotic device are carried out post processing to change its bullet Property coefficient.Such as, when invisible orthotic device is after artificial saliva soaks two weeks, its maximum stress and elastic modelling quantity Having raised, this is possibly due to, and material absorbs water thickening after artificial saliva is soaked, and causes the power of material Performance increases.

So, according to another detailed description of the invention of the present invention, S102 step determines one and rescues the stage Diacritical point, can suppress this series of dental appliance with the diaphragm of same thickness and material in S104 step, Then the dental appliance (including the second dental appliance) after stage diacritical point will be rescued through artificial Saliva or similar solution soaking two weeks so that its maximum stress and elastic modelling quantity have raised.Because not yet Having the elasticity through reprocessed appliance diaphragm preferable, patient wears the used time at the beginning can be more comfortable, and Its stress is less so that movement rate and the quantity of motion of tooth are less, so being adapted to first allow patient use. And poor through the elasticity of reprocessed appliance diaphragm, but its stress is bigger so that the motion speed of tooth Rate and quantity of motion are relatively big, use so being suitable for allowing after patient so that the Orthodontic force in later stage can strengthen.

Further, described in part A as mentioned in the above, successively suppress a series of in S104 based on a series of formpistons The dental appliance that diaphragm thickness is different.Then, it is further added by post processing sub-step, after stage diacritical point being rescued Appliance (including the second dental appliance) carry out post processing (being such as immersed in artificial saliva), Its elastic modelling quantity is increased.

It is of course also possible to a series of dental appliances all to be carried out post processing (being such as immersed in artificial saliva), And control the degree of post processing, such as, be immersed in the concentration of the time in artificial saliva or artificial saliva, as long as Ensure that the elastic modelling quantity rescuing the material of the housing of the second dental appliance worn after stage diacritical point is more than Rescue the first dental appliance before stage diacritical point.

Therefore, " applying different post-processing approachs " used in the present invention has both included for rescuing stage district Each width of the appliance before and after branch all applies post-processing approach, but the post-processing approach applied is different； Also include only for the dental appliance before rescuing stage diacritical point or the orthodontic after rescuing stage diacritical point Device application post-processing approach, the most also includes only locating after in the stage of rescuing, certain or certain several concrete steps are carried out The situation of reason.

D, increase adnexa rescue the dental appliance before and after stage diacritical point with manufacture

The type of the adnexa on invisible orthotic device and shape also result in its elastic force and produce change.On appliance permissible Including various adnexaes, adnexa can include at least one in depression, aperture, opening and/or projection.

Such as, in a kind of specific embodiment, form microprotrusion (it also may be used in the inner side of invisible orthotic device thin-walled It is referred to as correcting side stalk), for producing lateral corrective force, adjust Orthodontic force distribution and improve anchorage condition.Rectify The position of positive side stalk typically has at fluctuating corresponding to two tooth intersections or side of grinding one's teeth in sleep on appliance Near zone, the active force of side stalk is by mistake jaw (mainly tooth at two tooth intersections and side fluctuating of grinding one's teeth in sleep Tooth) side convex-concave and side stalk inner face and side tooth surface between frictional force realize.

In another kind of specific embodiment, can also install in the outside of appliance thin-walled and rescue hook, existing Traction apparatus be commonly attached on one or several teeth, be one the most reasonably anchorage form. And the rescuing hook and can be arranged on the thin-walled of dental appliance of the present invention, it can become with appliance one Shape, it is also possible to be formed separately and link together.The design of hook is except according to conventional hook design side Method can meet outside the requirement of traction, and under use state to be taken into full account, on hook, the counteracting force of pull strength makes Appliance produces the additional correction power of additional elastic deformation generation and the resilience force of appliance for traction apparatus The produced extra traction of impact.Actually rise correct and draw be the coupling of these power, just Locality utilizes both additional forces can form the distribution of more preferable anchorage and more reasonably corrective force and pull strength divides Cloth, thus obtain more preferable rectifying effect.

In another specific embodiment, on appliance, such as can also be formed multiple on the sidewall of appliance Opening, for adjusting the distribution of Orthodontic force.The shape of opening, position and size are according to the Spreading requirements of corrective force Design determines.In general, the generation elastic deformation in a state of use that opening is positioned on appliance sidewall mostly Relatively small, or need produce region that is less or that do not produce corrective force according to treatment, it is also possible to position In the occlusal surface of appliance, depending on the size and shape of opening is according to the size and shape of respective regions.

The ridge, above-mentioned rectification side, hook and opening play the distribution effect adjusting corrective force, and it can be by sun After mould utilizes pressing diaphragm to make appliance blank, then install and repair the rectification ridge, side or hook, or carry out again The processing of opening and finishing.

So, according to another detailed description of the invention of the present invention, such as in step S104, phase can be used The diaphragm of stack pile and material suppresses a series of variform dental appliances, then increases attachment design sub-step Suddenly, such as the first dental appliance before rescuing stage diacritical point is increased opening to reduce its Orthodontic force.Cause Less for having the Orthodontic force of the appliance of opening, patient wears the used time at the beginning can be more comfortable, and its stress Less so that movement rate and the quantity of motion of tooth are less, so being adapted to first allow patient use.And do not have The Orthodontic force having the appliance of opening is bigger so that the movement rate of tooth and quantity of motion are relatively big, so being suitable for allowing Use after patient so that the Orthodontic force in later stage can strengthen.

Again for example, it is possible to use same thickness different with a series of shapes of the diaphragm of material compacting in step S104 Dental appliance, then on the second dental appliance rescuing after stage diacritical point increase hook with produce Raw lateral Orthodontic force so that rectifying effect optimization.

And, (the possible application after not only including various adnexaes recited herein but also including of various adnexaes Various adnexaes) can suppress a series of with the diaphragm of same thickness and material according to practical situation combination in any After variform dental appliance, rationally changed by increase adnexa before and after rescuing stage diacritical point The Orthodontic force size of dental appliance so that rectifying effect and rescue comfort level optimization.

Further, " with/different adnexa of increase " used in the present invention had both included rectifying for a series of teeth The each width controlling device all increases adnexa, but the adnexa increased is different；Also include for a series of orthodontics In device, part dental appliance adds adnexa, but other appliances the most do not increase the situation of adnexa.

It should be noted that in actual applications, both can be by individually having considered above A, B, C, D side Single method in method, it is also possible to the multiple methods in cross-application above method reach optimum efficiency.Such as, Thickness and material can be manufactured based on the tooth model that tooth model preparation is rescued before or after stage diacritical point The most different dental appliance, or can prepare variable thickness sample and adnexa arranges different tooth and rectifys Control device etc..Various combinations are included within the scope of the present invention.

It is not required to the appliance manufacture method of formpiston

Appliance manufacture process shown in Fig. 2 is only a kind of exemplary technique, and those skilled in the art can be right It makes various change.For example, it is also possible to generate former (negative norm type) based on described tooth target state data Data, directly have the invisalign of respective shapes based on above-mentioned former data by rapid shaping technique manufacture Device.

Fig. 3 show the another kind of detailed description of the invention according to the present invention for by " Direct Manufacture Process " Manufacture an example process of the method for dental appliance.First, in step s 201, expression one is obtained A series of tooth digitized data models of series orthodontic state.About specifically how obtaining include corresponding to the One rescues the stage and second rescues the first tooth digitized data model of orthodontic state and second tooth in stage Tooth digitized data model is at the interior a series of tooth digitized data models representing a series of orthodontic states Method is referred to above step S101, is not repeated at this.

It follows that in step S202 can according to the health status of the tooth accommodated, malocclusion type, The individual demands such as the oral healthy condition of patient, age, sex and pain sensitivity determine one or many Individual rescue stage diacritical point.About specifically how determining that one or more stage diacritical point of rescuing is referred to above Middle step S102, is not repeated at this.

It is also noted that after step S102 is not necessarily located at step S101 step.In practice, Before step S102 is also possible to be positioned at step S101 step.Such as, doctor can be abnormal according to the wrong jaw of patient The situations such as shape type, oral healthy condition and pain sensitivity first determine rescues stage diacritical point.When according to step When rapid S101 generates a series of tooth digitized data model representing a series of orthodontic states, further according to this Front stage of the rescuing diacritical point determined is to should determine that corresponding tooth digitized data model accurately.

Because dental appliance is configured to have the geometry of cavity accommodating tooth, i.e. its substantially with rescue On jaw corresponding to device one or multiple teeth are consistent, and can accommodate or close to replicating every tooth Reversely shape.So, first can be based on the formpiston type of the representative orthodontic state obtained in step S201 Rescue the stage diacritical point method by traditional computer digital animation determined by S202, such as, calculate The method of machine Aided Design (CAD), by offsetting out a certain distance (about from the crown surfaces of each tooth 0.05mm or more), obtain and represent what the basic phase with the outline of this orthodontic state " was coincide " The digitized data model of the inner surface of dental appliance (former type).

Specifically, first, can be according to a series of tooth numerical data moulds representing a series of orthodontic states Type and rescue stage diacritical point, the health status of tooth accommodated in conjunction with patient, malocclusion type, patient Oral healthy condition, age, sex and pain sensitivity, further determine that before rescuing stage diacritical point After the different-thickness rescuing dental appliance corresponding to the stage, such as, can set the thickness of appliance as 0.2-1mm, but this thickness can be according to making material and rescue the difference of requirement and different.

Directly appliance digitized data model is changed it follows that processed by rapid shaping in step S203 Become dental appliance.

Can swash according to the above laser fast forming SLA, layer separated growth LOM, selectivity Light sintering SLS, Fused Deposition Modeling FDM and 3 D-printing manufacture the quick molding methods such as 3DP to being divided The appliance digitized data model of layer is processed, to manufacture the dental appliance of physics.Such as, have in one In body embodiment, the method using 3 D-printing to manufacture 3DP manufactures the physical model of dental appliance.

Further, the detailed description of the invention according to A ' to E ' detailed below performs above-mentioned S201-203 step Rapid detail.

A ', a kind of detailed description of the invention according to the present invention, in described step S202, according to representing that one is A series of tooth digitized data models of row orthodontic state and stage of the rescuing diacritical point determined, in conjunction with patient The health status of the tooth accommodated, malocclusion type, the oral healthy condition of patient, the age, sex, And pain sensitivity, after generating before rescuing stage diacritical point and rescue diacritical point, the tooth of different-thickness is rectified Control the digitized data model of device, thus in step S203, produce first group of dental appliance that thickness is different (including the first dental appliance) and second group of dental appliance (including the second dental appliance).The most permissible To the numerical data mould representing the basic dental appliance " coincideing " with the outline phase of this orthodontic state Type is finely adjusted joint, designs the appliance digitized data model with different-thickness personalizedly.

Such as, set the dental appliance digitized data model before rescuing stage diacritical point relatively thin, rescue the stage Dental appliance digitized data model after diacritical point is thicker so that prepared physics rescue the stage Dental appliance before diacritical point is relatively thin, and the dental appliance after rescuing stage diacritical point is thicker.

B ' and according to another detailed description of the invention of the present invention, in step S203, utilize different elastic The material manufacture of modulus rescue stage diacritical point before and rescue the dental appliance after stage diacritical point.Example As, the material preparation utilizing elastic modelling quantity big rescues first group of dental appliance before stage diacritical point (wherein Including the first dental appliance), and the material preparation utilizing elastic modelling quantity little rescues after stage diacritical point the Two groups of dental appliances (including the second dental appliance).

C ' and according to another detailed description of the invention of the present invention, described step S203 adds post processing Sub-step, for by a series of dental appliances obtained by quick molding method, applying different post processings Method so that obtained rescue stage diacritical point before first group of dental appliance (include that the first tooth is rectified Control device) and second group of dental appliance (including the second dental appliance) after rescuing stage diacritical point have Different Orthodontic force.Concrete post-processing approach is referred to C portion above, is not repeated at this.

D ' and according to another detailed description of the invention of the present invention, described step S202 adds adnexa and sets Meter sub-step, a series of teeth numeral representing a series of orthodontic states obtained based on step S201 Data model, the health status of tooth accommodated in conjunction with patient, malocclusion type, the oral health of patient Situation, age, sex and pain sensitivity, generation rescue stage diacritical point before and rescue stage district The digitized data model of the dental appliance that the rear attachment facilities of branch is different, thus in step S203 Manufacture and rescue the dental appliance that adnexa facilities before and after stage diacritical point is different.

Specifically, can be in described step S202, for a tooth rescued before stage diacritical point Digitized data model generates basic dental appliance digitized data model, then at the basic dental appliance of this group On digitized data model, the digitized data model increasing adnexa is set so that stage of the rescuing diacritical point designed Appliance digitized data model before with rescue stage diacritical point after appliance digitized data model attached It is different that part arranges situation, thus produce in step S203 rescue stage diacritical point before and rescue stage district The dental appliance that adnexa facilities after branch is different.

E ' and according to another detailed description of the invention of the present invention, described step S203 adds adnexa and sets Meter sub-step, directly manufacturing one at the appliance digitized data model identical according to a series of adnexa facilities is After row dental appliance, then carry out adnexa processing and finishing so that described in rescue before stage diacritical point first group Dental appliance (including the first dental appliance) and rescue second group of dental appliance after stage diacritical point (including the second dental appliance), upper adnexa facilities was different.

It should be noted that and the invention is not limited in only different appliance is used different thickness or attached The situation that part is arranged.For the different tooth position on same appliance and/or the different parts of same teeth position, it is possible to With the housing at some tooth position of personalized customization or some position elastic (such as: make a certain tooth position or certain The thickness of shell at position is different, utilize the material of dual extension-compression modulus to prepare the shell at a certain tooth position or certain position Body or the housing for a certain tooth position or certain position carry out different adnexaes and arrange) so that different The elastic force produced when elastic deformation because of appliance suffered by tooth different, thus control to be applied to difference The size of the Orthodontic force on tooth, reaches to control translational speed and the purpose of amount of movement of different dental.Such as, In certain specific embodiment, the health status of tooth that accommodated according to patient, malocclusion type, The situations such as the oral healthy condition of patient, age, sex and pain sensitivity, before step S202, Increase the sub-step that the housing elasticity for different tooth position or the different parts of same teeth position is adjusted, thus make Produce the different parts thickness of different tooth position or same teeth position or the dental appliance that adnexa facilities is different, real The now Orthodontic force of concrete tooth position and the difference rescuing mode.

In sum, according to the method directly manufacturing dental appliance of the present invention, rescue step for a series of, Have only to calculating and determine a series of tooth digitized data model, just can be not required to formpiston directly manufacture a series of difference rectify Control the dental appliance of power, thus accelerate the design of the scheme of rescuing so that rectifying effect and rescue comfortable Degree is all improved, and also shortens the time of rescuing.

A kind of combined orthodontic system

One combined orthodontic system as shown in Figure 4, this system includes the first dental appliance and second Dental appliance, described first dental appliance includes that the first housing is for accommodating and positioning teeth, Yi Jisuo State the second dental appliance and include that the second housing is for accommodating and positioning teeth, it is characterised in that described first Housing and the geometry of the second housing and elasticity all differ.

And according to the manufacture method of appliance mentioned above, the manufacture of stealthy dental appliance is based on a series of Gradually navigated to expect the tooth digitized data model of dental phenomenon by basis dental phenomenon, dental appliance is final Corresponding with these tooth digitized data models.So in certain embodiments, this combined orthodontic It is different selected several that system includes that a series of dental appliance gradually used, described a series of dental appliances have The cavity accommodating tooth that tooth is gradually navigated to from basis dental phenomenon expectation dental phenomenon of what shape.

Simultaneously during concrete orthodontic, the appliance quantity that overall orthodontic system is used is also Non-constant.It is said that in general, step rescued by whole process needs at least 4 of rescuing, it is sometimes desirable to rescue for 20 Step, for some complicated case, needs 40 and the most more rescues step.And each rescue step pair The quantity of the dental appliance answered is one or more.

For whole orthodontic process, at the orthodontic initial stage, often there is longer fitting in patient Answer process, now use elastic preferably dental appliance, often make easier acceptance and the cooperation of patient, Improve the whole comfort level rescuing process.In the later stage rescuing process, the most gradually adapt to tooth due to patient and rectify Control the use of device, now use elastic poor dental appliance, it is possible to increase tooth is rectified by dental appliance Control power, improve the mobile efficiency of tooth, thus reach preferable tooth and move control.So, concrete at some Embodiment in, the elasticity of described first housing is more than the elasticity of the second housing.First dental appliance is used for Being worn on the tooth of patient at the initial stage of rescuing, the second dental appliance is for being worn on patient's tooth rescuing the later stage On tooth.

And the elasticity of dental appliance is relevant with many factors, the thickness of such as dental appliance, the bullet of material Property modulus, the method for post processing and adnexa facilities etc..First dental appliance and the second dental appliance Elastic different, refer between the first dental appliance and the second dental appliance thickness, the elastic modelling quantity of material, A post-processing approach and adnexa facilities at least difference, but it is not limited to any one therein.

As described in appliance manufacture method above, the elastic size of dental appliance and thickness relevant.Thickness The biggest, the elasticity of dental appliance is the least；Thickness is the least, and the elasticity of dental appliance is the biggest.Have at some The embodiment of body, the thickness of described first dental appliance is less than the second dental appliance, and becomes certain ratio Example relation.Such as, in a concrete combined orthodontic system, there is the first tooth that thickness is different Appliance and the second dental appliance, the used chaff thickness of described first dental appliance is the second orthodontic The 70% to 95% of the thickness of device used chaff, it is preferred that the thickness of the first dental appliance used chaff is The 82% to 88% of the thickness of the second tooth used chaff appliance.A kind of specific embodiment party according to the present invention Formula, such as, in step S1041, rescue the first dental appliance used chaff before stage diacritical point Thickness is 0.5 to 0.65mm, and rescues the thickness of the second dental appliance used chaff after stage diacritical point Degree is 0.70 to 0.80mm.
