Detailed description of the invention

The following detailed description refer to constitute the accompanying drawing of this specification part.Mentioned by specification and drawings Exemplary embodiment only merely for being illustrative purpose, be not intended to limit the scope of the invention. It will be understood by those skilled in the art that and can also use other embodiments many, and can be to described Embodiment makes various change, without departing from purport and the protection domain of the present invention.It should be appreciated that These various aspects of the invention illustrating and illustrating can arrange according to the most different configurations, replace, combine, Separating and design, these different configurations are included in the present invention.

Present invention provide for determining the method and system of target dentition layout, by the method applying the present invention And system, it is possible to according to the biological integrities such as original dental gear mutation, alveolar bone and the face structure of patient because of Element, determines the target dentition layout wishing to obtain and can obtain after rescuing quickly and accurately, so that The biological integrity theory of correcting is incorporated in NITI Ω arch wire and the row's tooth design of orthodontic computer and be possibly realized, and And can just allow patient can be can achieve the effect that after being fully understood by orthodontic, so carrying before rescuing beginning High biological safety, reasonability and the effectiveness of orthodontic design.

For orthodontic, determine the target dentition layout after rescuing, especially each tooth in denture Target location be very important.For some row's tooth method, it is thus necessary to determine that the tooth after rescuing Target location determines the tooth position corresponding to each row's tooth stage, each row's tooth stage that then design is corresponding the most again The dental appliance being suitable for, like this, determines each tooth of a rational denture meeting medical science rule Target location is considerable.But, it is the most all to be determined tooth target by clinician according to personal experience Position, then indicated manual mobile each tooth to determine each tooth in denture by row tooth operator according to doctor The target location of tooth, because clinician's level differs, thus uneven to the handle control degree of row's tooth result, Determined by such an extent as to, tooth target location can not realize optimization.

Therefore, the present invention proposes a kind of method and system based on " crucial tooth " denture that really sets the goal layout, Further, allow quick, convenient, automatic according to a kind of detailed description of the invention of the present invention, said method and system Change or determine target dentition layout semi-automatedly, being especially suitable for determining target dentition cloth by computer system Office.Hereinafter, exemplarily will illustrate for the present invention with reference to Fig. 1.

Fig. 1 shows the side for determining target dentition layout according to a specific embodiment of the present invention The flow chart of method.In the method shown in Fig. 1, receive the most in the step s 100 and represent original dental Column Layout Raw data set, wherein, described raw data set include original denture (maxillomandibular at least one tooth, Be preferably maxillomandibular all teeth) form and position data, so described raw data set include representing to The data set in the home position of a few crucial tooth.To be explained respectively below.

Such as, the data of the original denture of the data of original denture for example, patient.Wherein, described patient's is former Before beginning denture layout (the most original denture, current denture or current denture layout) represents the rescuing of patient Denture on the original form of each tooth that includes and position.

The described data representing original dental Column Layout, such as, represent the mathematical model of original dental Column Layout, Ke Yitong Cross multiple method to produce.For example, it is possible to obtain denture ordered state by impression taking, thus generate physics tooth Mould.Also optical scanning, X-ray imaging, ultra sonic imaging, tri-dimensional photographing, three-dimensional camera shooting, Medical CT can be passed through The methods such as scanning or nuclear magnetic resonance, NMR directly obtain the image of tooth or tooth and perienchyma thereof.Further, Can be by the scanning to physics tooth mould or the computer disposal to oral cavity tissue image, by collected Denture layout or tooth and perienchyma's State Transferring thereof become denture topology data collection, thus can get tooth X in three dimensions, Y, Z coordinate, it can visualize display on the graphical interfaces of computer system And manipulated (such as translate or rotate).Here, the mathematical model representing original dental Column Layout can be former The maxillary dentition of beginning denture layout and/or the mandibular dentition of original dental Column Layout.

Typically, it is possible to use commonly known technology first obtains the plaster model of patient's denture by die, Then by scanner, the plaster model of patient's denture is scanned, thus produces denture topology data collection.Its Middle scanner such as can include non-contact laser scanner and contact-type laser scanner etc..And by scanning Data set produced by instrument may present any one of various number format, so that it is guaranteed that and software compatible Property.

It should be noted that, the present invention is not limiting as the method for obtaining original dental Column Layout.Such as, also may be used To be obtained the data of original dental Column Layout by image system in oral cavity.In oral cavity, image system is to allow dentistry In practitioner sees patient oral cavity and show the diagnosis of the surface configuration characteristic of tooth on a display monitor Equipment.In some three-dimensional (3D) oral cavity, image instrument can include the intra-oral camera of band light source.Shadow in three-dimensional oral cavity As instrument can be inserted the oral cavity of patient by dental practitioner.After in oral cavity, image instrument is inserted into oral cavity, dentistry Practitioner can catch the image of the visible part of tooth and gingiva.And the figure that intra-oral camera captures As may be displayed on display monitor, and calculating equipment can be sent to, thus obtain original denture cloth The data of office.

And, described denture layout is possible not only to include the state of corona, it is also possible to include the state of root of the tooth.Example As, can be by two-dimentional or three-dimensional x-ray system, CT scanner and nuclear magnetic resonance equipment etc. obtain tooth Root and the data of perienchyma.

Because the mathematical model representing original dental Column Layout can be the maxillary dentition of original dental Column Layout and/or former The mandibular dentition of beginning denture layout, if the mathematical model representing original dental Column Layout is the upper of original dental Column Layout Jaw denture and mandibular dentition, then the paraffin patient bites and can be used to obtain the upper jaw under central occlusion state Relative position with mandibular dentition.Such as, for laser scanning, can be by lower jaw tooth current for patient First place paraffin on the plaster model of row to bite, then according to paraffin bites, then on mandibular dentition, place the upper jaw Denture, so that upper mandibular dentition bites according to paraffin determines relative position, at this moment carries out laser scanning, The upper lower jaw dental arch model that relative position intraoral with patient is same is represented it is thus possible to obtain.It is of course also possible to Individually scanning paraffin bites, and the data bitten by scanning paraffin are tied mutually with by the data of scanning plaster model Close thus obtain representing the upper jaw and the mathematical model of mandibular dentition of patient original dental Column Layout.

Further, in this step, it is also possible to the mathematical model being based further on obtained denture obtains each The mathematical model of tooth.That is, automatically split by computer, manually split or automatically and manually combine Partitioning scheme can will above by scanning obtain maxillary dentition and/or mandibular dentition mathematical model segmentation Become the mathematical model of every tooth, and determine the coordinate of every tooth.

Certainly, in the step s 100, as it has been described above, according to a kind of detailed description of the invention, can first obtain whole The mathematical model of individual maxillary dentition and/or mandibular dentition is sub-partitioned into the mathematical model of every tooth.And according to separately A kind of detailed description of the invention, it is also possible to first the plaster model of the denture obtained by die is split, with To the plaster model of single tooth, and record every tooth position in denture or the mutual alignment between tooth Relation, is then scanned every tooth, to obtain the mathematical model of every tooth, then according to record Every tooth position in denture or the mutual alignment relation between tooth, thus obtain whole in a computer Individual denture, i.e. represents the mathematical model of patient original dental Column Layout.Above-mentioned detailed description of the invention is exemplary And it is nonrestrictive, as long as the method that therefore can obtain the mathematical model representing patient original dental Column Layout belongs to Protection scope of the present invention.

Further, in step s 110, acquisition represents the parameter set of head construction.It should be noted that step 100 and the execution order of step 110 can exchange, and these two steps also can be carried out simultaneously Or merging is carried out.The present invention not execution order or mode to above-mentioned two steps carries out any restriction.

The parameter set representing head construction can include a shadow data set.Further, it is preferred that it can also wrap Include dentistry statistical parameter collection, CT based on tooth and head construction figure and the parameter etc. that obtains.

First a shadow data set below will be described.It is said that in general, the measurement of tooth jaw and skull model mainly connects Touch measurement and non-contact measurement two kinds.Contact type measurement is mainly by various measuring instruments dentognathic model Carry out direct contact measurement, be divided into again manual contact to measure and pin touches mechanical measurement.Wherein hand dipping is a kind of Traditional measuring method, is the most still widely used, and main tool is: ruler, divider, slide gauge and Universal protractor, it is a kind of two-dimensional measurement method, has cost few, it is adaptable to clinical individual models is measured Advantage, but shortcoming is owing to use instrument is hard, thus anhydrite must be recorded, simultaneously need to substantial amounts of space Stored models, thus waste time and energy, precision is the highest.

And non-contact measurement is to reconstruct dentognathic model 3-D view through optical instrument and computer software, its Fine structure is clear and legible, not only can arbitrarily rotate or translate for observing and each portion on measurement model surface Position, the three-dimensional coordinate that also can complete arbitrfary point extracts, space any two points distance, arbitrarily angled, arc length and song The measurement analysis of the items such as face area, the index making hand dipping to relate to is possibly realized, and convenient, directly perceived. U.S. Broadbent in 1931 and Germany Hofranth have founded x-ray head locating measurement method, and x-ray is just Lateral projection analysis becomes research tooth jaw and the important method of skull model.Along with the development of computer technology, head Shadow is measured and is developed into the current exploration analyzing full-automatic image measurement from initial manual described point measurement, improves Precision and efficiency.And, the most domestic, abroad have computer cephalometric analysis method and corresponding the most successively Software produces, the digital cephalometric software such as such as WinCeph, OnyxCeph.

It is to be noted, however, that the method that the present invention is not limited to obtain head shadow data by x-ray. Development along with the such as imaging technique such as CT, nuclear magnetic resonance, NMR, it is possible to obtain more accurate head shadow data.Such as By being combined with digital computer by cone beam tomoscan (CBCT), tooth and surrounding skeleton knot can be obtained The image of structure, soft tissue, muscle, blood vessel etc..During CBCT scans, CBCT scanner is around patient's head Portion rotates and can obtain the CBCT image that hundreds of width is different, and these CBCT images can be referred to as CBCT Image.CBCT image can be sent to calculating equipment thus can produce 3 D anatomical data.Then can use 3 D anatomical data are operated and visualization processing by special software, in order to carry out the head shadow of CBCT image Measure and analyze.

Hereinafter, as a example by the process to be obtained head shadow data by X-ray, illustrate.Such as Fig. 2 A-2B Shown in, first, by X-ray camera technique, under the strict location of cephalometer, obtain such as Fig. 2 A Shown study of lateral skull radiography head image, and be entered in computer, thus obtain the initial data of head construction Collection.

Then, such as, after the study of lateral skull radiography head image obtaining numeral, available digital cephalometric software, Such as WinCeph software (as shown in Figure 2 B obtain hatched bars to the end according to x-ray head image) obtains such as figure Head shadow figure in 2C.Although it should be noted that in the application and being situated between as a example by the mode of Digitization Software Continue the present invention, but the present invention is not precluded from manual contact formula and measures or the mode of hand drawing head shadow figure.

Medically, each scholar proposes different cephalometry methods and corresponding cephalometric landmark, mark Will plane and index angle.Such as, the index point of conventional cephalometry includes: cranium index point (such as wraps Include sella turcica (S.sella) and auriculare (P.porion) etc.), upper jaw index point (such as include margo alveolaris point (SPr.superior prosthion) and ui (UI.upper incisor) etc.), lower jaw index point (such as wraps Include condylion (Co.condylion) and lower incisor (Li.lower incisor) etc.), soft tissue hand mark point (example As included eyespot (E.eye), nasion of soft tissue (NS nasion of soft tissue) and vermilion borders (vermilion Borders) etc.).

Further, conventional mark plane includes datum plane and measures plane, and wherein datum plane is to survey at head shadow As metastable plane in amount.The most the most frequently used datum plane is sn (SN), eye ear Plane (FH) and aesthetic plane (EP).Measure plane and then include palatal plane (ANS-PNS), full basis cranii Plane (Ba-N), closes plane (OP) and lower jaw plane (MP) etc..Thus, datum plane and each surveying marker point And other measurement interplanars constitute 8 measure the items such as angle, line-spacing, ratio.

Such as, as shown in Figure 2 D, 1 sn is represented；2 represent eye-ear plane；3 represent bite plane； 4 represent lower jaw plane；5 represent aesthetic plane.

Further, it is possible to determine a shadow angle.Conventional cephalometry angle includes: SNA angle is (by sella turcica The angle that center, nasion and upper teeth groove seat point are constituted), NP-FH (also referred to as angle, face, i.e. facial plane NP The posterior angle intersected with eye-ear plane FH), the SN-MP angle of cut of lower jaw plane (sn with), MP-FH (also referred to as mandibular plane angle, it is by the angle of cut of lower jaw plane (MP) Yu eye-ear plane (FH)), 1 " TXX-"-SN angle (the lower interior angle that upper central incisor major axis intersects with SN plane), 1 " TX-"-MP angle (lower central incisor major axis intersect with lower jaw plane on interior angle) and the FMA (friendship of eye-ear plane and lower jaw plane Angle) etc..

And the conventional line-spacing of cephalometry includes: ANS-Me (lower the highest)；S-Go (the highest)；N-Me (the highest), and conventional ratio include S-Go/N-Me (rear-the highest than), ANS-Me/N-Me (under -the highest ratio) etc..

It should be noted that above-mentioned each measure the item has its specific meaning, the feature of corresponding construction is described Or growth change trend.But, evaluate an index in isolation and often can cause the conclusion of mistake.Because head is The complex of tooth jaw, cranium face Each part composition.Whether normal it is does not depends entirely on a certain index: and Depend on the cooperation between each several part, it is therefore desirable to consider.And malocclusion is each just because of tooth jaw, cranium face Uncomfortable caused between portion.

The most proposed by the invention by measuring every shadow parameter, and mainly utilize head shadow parameter, and tie Close the method that other parameters design the denture position after rescuing such that it is able to by the angle of root of the tooth and alveolar bone/ Position relationship, oral cavity hard and soft tissue health and articulation health such biological integrity structure problem and face Aesthetic problem considers, and meets medical science and aesthstic dentition goal position when participating in the cintest to design.

Further, in the step s 120, described parameter set is utilized, based on representing the former of at least one crucial tooth The data set of beginning position, determines the crucial tooth of representative at least of the target location representing at least one crucial tooth The data set of target location.Further, further, in step s 130, according to described representative at least pass The data set of the target location of key tooth, determines the representative target dentition cloth of the target location representing described original denture The target data set of office.

Here, first, the present invention proposes the concept of " crucial tooth ", and " crucial tooth " refers in denture Including a certain or several teeth, it plays an important role for the position determining whole denture.And for former Beginning denture rescue after the determination of target location, including vertical, laterally and front and back on three dimensional space coordinate Target location determines.The most hereinafter by for how determining that the target location in each direction is specifically introduced.

1, determine that row's tooth is vertically to location

First, according to a kind of detailed description of the invention of the present invention, described target location include vertically to target position Put, and in order to determine whole denture vertical to target location, select using maxillary first molar as crucial tooth. So, in the first detailed description of the invention, in the step s 120, need to utilize the parameter set obtained, Determine and represent vertical at least one key of representative to target location intentionally got after maxillary first molar is rescued The data set of the target location of tooth.

As described above, the parameter that cephalometry is obtained has a lot, in a kind of detailed description of the invention of the present invention In, select with head shadow angle FMA and SN-MP, and head shadow ratio S-Go/N-Me is major parameter Determine that maxillary first molar intentionally gets after rescuing vertical to target location.

Fig. 3 shows the tooth bitmap of the whole denture of normal person, wherein all marked specifically for each tooth Numbering.It should be understood, however, that some patient or teen-age denture do not comprise as shown in Figure 3 All teeth, Fig. 3 is only intended to illustrate the position of each tooth, is not limited to the present invention.

Wherein, maxillary first molar includes that tooth bit number is 16 or 26 grind one's teeth in sleep (i.e. left side or right maxillary the One grinds one's teeth in sleep).Here, it is preferred that the upright position of left side and right maxillary first molar is adjusted to basic Unanimously, then vertical to position according to left side or right maxillary first molar, determine the vertical of whole denture To position.But it is also possible to maxillary first molar determines the vertical to position of whole denture on the left of only utilizing, Or utilizing right maxillary first molar to determine the vertical to position of whole denture, this is not limited by the present invention System.

First, FMA is the angle of cut of eye-ear plane and lower jaw plane, as shown in Figure 4 A.Normal with ethnic group FMA angle substantially very close to, such as, can determine that the FMA's of normal Chinese according to Tweed analytic process Measuring average is 31.3 degree (standard deviation is 5.0 degree).

And the angle of cut that SN-MP is sn and lower jaw plane, as shown in Figure 4 B.Equally, normally same The SN-MP angle of ethnic group substantially very close to, such as normal Chinese is in the measurement average of the SN-MP for the tooth phase It is 35.8 degree (standard deviation is 3.6 degree), and the measurement average of the SN-MP of permanent dention is 32.5 degree of (standards Difference is 5.2 degree).

If FMA and SN-MP angle is higher than average range, just for the angle of elevation；And FMA and SN-MP Angle is less than if average range, just for low angle；On the other hand, FMA and SN-MP angle falls within average model If enclosing, just for equal angle.

And head shadow ratio S-Go/N-Me (rear-the highest ratio), as shown in Figure 4 C, S-Go/N-Me (rear- The highest than) normal rate is about 62%, it is an important indicator, and ratio is excessive shows that face is in level Sagittal direction grows, otherwise shows that face grows in vertical direction.

Therefore, based on measured above-mentioned head shadow parameter, and combine above-mentioned dentistry statistical data and may determine that the upper jaw First molar vertical to position.Such as, if by FMA and the SN-MP angle of patient, comprehensively sentenced If disconnected its belongs to the angle of elevation or equal angle case, then maxillary first molar can not design elongation；And if low angle is sick If example, then maxillary first molar can not design press-in.Meanwhile, by adjusting the vertical position of maxillary first molar Put, maintain the scope of S-Go/N-Me about normal rate.

It should be noted that above-mentioned design is the case extended without pathologic for maxillary first molar, if on Jaw first molar has the case that pathologic extends, with maxillary first premolar (teeth of i.e. 14 or 24 tooth positions) Or the vertical height of the upper jaw the second premolars (teeth of i.e. 15 or 25 tooth positions) replaces, i.e. in this situation Under, determine that the vertical crucial tooth to height can be maxillary first premolar or the upper jaw the second premolars.
