Description

Transparent Calibrator Manufacturing Method

The present invention relates to a method for manufacturing a transparent calibrator, and more particularly, to a method for manufacturing a transparent calibrator that can reduce pain and improve orthodontic power and improve aesthetics during a calibration period.

In general, non-uniform dentition, malocclusion and facial protrusion are caused by the teeth and oral and maxillofacial regions not growing properly in place due to abnormal development of teeth or jawbone, bad habits or heredity affecting the teeth. Orthodontics and the structure of the oral cavity acts as a determinant of the impression of the person, and cause a decrease in the grinding function of food, so interest in orthodontics is increasing day by day.

Orthodontic treatment uses the property of a tooth to move under some force. The most widely used for orthodontic treatment is a fixed treatment method that attaches a bracket to a tooth and moves the tooth using elasticity such as orthodontic wires and rubber bands. Brackets are usually made of metal, with the disadvantage of being noticeable during treatment.

In order to solve this disadvantage, a transparent calibration method has been proposed. Transparent orthodontics is a procedure to make a transparent orthodontic appliance that changes step by step from the state of the tooth before the correction to the state of the tooth to be corrected, and to correct the orthodontics by changing it to the tooth.

Specifically, the procedure by the transparent orthodontic device was developed in 1997, is a dental orthodontic device developed by the US "Align Technology, Inc." under the name "Invisalign System", US Patent No. 5,975,893 And 6,217,325 and the like. The "Invisalign System" cuts teeth one by one on a computer using a special program for three-dimensional scan data of the teeth, and creates 20-30 pairs of models in stages to the position where the teeth should finally move through virtual simulation. It is to make a transparent plastic frame that can move teeth by model and distribute it to patients.

The "Invisalign System" is characterized by inserting a series of prepared plastic orthodontics into the teeth step by step, which gradually moves the teeth to be corrected to the final target point. Since it is not recognized, it can be a great help in the daily social life of orthodontic patients, and it can be said that the patient can attach or detach the orthodontic device as needed.

However, although the transparent calibrator has the advantages as described above compared to the fixed orthodontic device by the bracket described above, the situation is not much pain to the patient.

In other words, such transparent orthodontic treatment is to induce the tooth arrangement by using a hard sheet (硬質) due to the nature of the material to ensure the aesthetics, because of the rigid material properties of the transparent orthodontic device is hard, there is not much pain to the patient.

In addition, despite the many advantages of the braces, what is worse than the stationary orthodontic device is that if the device does not fit well during tooth movement, the device is not well seated and the desired tooth movement is difficult.

On the other hand, the teeth of the braces are discolored, extracted or vacant, teeth with space between the teeth, teeth are broken, unshaven, malformed, or open bites with anterior bite If it is open, the teeth may be jagged with the cross bite. In this case, even though the braces are worn by the braces, the current state of the teeth is all exposed to the outside, which causes aesthetic problems.

An object of the present invention is to solve the above-described problem, to provide a method of manufacturing a transparent braces that can quickly exhibit the effect of orthodontics while reducing the pain of the corrector.

Another object of the present invention is to improve the effect of the correction in consideration of the shape and size of the teeth in addition to the basic correction conditions of the corrector in the manufacture of the transparent braces, transparent that can help long-term teeth correction It is to provide a method of manufacturing a calibrator.

In order to fully understand the present invention, preferred embodiments of the present invention will be described with reference to the accompanying drawings. Embodiment of the present invention may be modified in various forms, the scope of the invention should not be construed as limited to the embodiments described in detail below. This embodiment is provided to more completely explain the present invention to those skilled in the art. Therefore, the shape of the elements in the drawings and the like may be exaggerated to emphasize a more clear description. It should be noted that the same members in each drawing are sometimes shown with the same reference numerals. Detailed descriptions of well-known functions and configurations that are determined to unnecessarily obscure the subject matter of the present invention are omitted.

1 is a flow chart schematically showing a method of manufacturing a transparent calibrator according to the present invention. As shown, the method for manufacturing a transparent brace according to the present invention comprises the steps of obtaining tooth data by three-dimensional scanning the teeth of the corrector (S110), inputting the correction conditions to be corrected teeth of the corrector (S120), Inputting supplementary correction conditions to be further corrected in addition to the basic correction condition (S130), inputting an aesthetic condition to impart an aesthetic feeling to the teeth of the corrector during the correction period (S140), and basic correction conditions and auxiliary correction conditions And forming a transparent calibrator corresponding to the calibration data in which all of the aesthetic conditions are reflected (S150).

Orthodontic teeth data can be obtained by directly scanning through the 3D scanner for the teeth of the current state of the braces, or obtained by scanning the tooth bones through the acquisition of the impression of the braces, or can use radiation equipment such as CT or panorama.

The tooth data obtained in this way is input to the 3D modeling software, and the teeth of the corrector's teeth are gradually moved and rearranged to the desired tooth arrangement by gradually reflecting the basic correction condition, the auxiliary correction condition, and the esthetic condition of the teeth. During orthodontic periods, a plurality of orthodontic data may be generated to impart aesthetics. In addition, a dental molding model may be formed based on the generated dental correction data, and the transparent sheet may be vacuum-extruded to form a transparent straightener, or a transparent straightener may be directly molded through a 3D printer. The aesthetic parts required by the aesthetic condition may be integrally coupled to the inside of the transparent calibrator, and may be attached to the outside of the transparent calibrator in some cases.

On the other hand, in some cases, the auxiliary orthodontic condition and the aesthetic condition of the tooth may be related to each other, or may be ambiguous. In this case, the aesthetics and the correction power may be given together by inputting the tooth data without distinguishing between the auxiliary correction condition and the aesthetic condition of the tooth.

Here, the basic straightening condition of the tooth in the input step S120 of the basic straightening condition refers to the straightening conditions required for the teeth that need to be corrected among the teeth of the straightener. The basic correction conditions may be rotational correction for rotating the teeth, correction of the fixed or pressed tooth, tooth correction for straightening the inclinedly formed tooth axis, and the like. In addition, the basic calibration conditions include various dental and skeletal mismatches, such as inverse occlusion, open occlusion, overbite, ambush, loss, and malocclusion.

While entering the basic calibration conditions, the calibration data for a plurality of transparent calibrators are generated to be gradually moved to a desired range from the current dental state to the desired state.

The transparent braces 100 are inserted into the teeth and apply the corrective force in the direction in which the teeth are to be corrected. 2 is an exemplary view showing an example of the transparent calibrator 100 of the present invention.

The transparent braces 100 are formed on the transparent orthodontic body 110 inserted into the teeth so as to correspond to the teeth form of the teeth. At this time, the transparent calibrator 100 according to the present invention does not need to excessive movement at once, and is formed to apply pressure with a weak force to the periodontal ligament of the tooth to be moved in a well-formed state. This induces direct bone resorption to speed up tooth movement.

Conventionally used injeolline and ecliner can cause pain to the patient because it induces a large range of movement by 0.5 ~ 1mm at a time. If strong pressure persists, indirect absorption causes the tooth movement to appear slowly in 7 to 14 days and accompany pain. In addition, since the correction width between the transparent tooth brace of the next stage and the transparent tooth brace of the previous stage is large, a longer time is required to fit the transparent tooth brace of the next stage to the teeth. Putting the next clear tooth straightener in place quickly will not fit well and the calibration will not work as desired. In this case, there may be a case where the impression is redrawn in the middle of the calibration and the transparent calibration apparatus is rebuilt.

On the other hand, the transparent braces 100 of the present invention by applying a weak pressure continuously to direct absorption so that the tooth movement appears quickly in 1 to 2 days. In this case, the patient feels little pain. In this way, the transparent braces 100 of the next stage are manufactured in a form that suits the current dental condition so that the correction proceeds smoothly without pain.

Since the transparent calibrator 100 of the present invention induces direct bone absorption generates a faster correction effect, the average periodontal ligament space is 0.25mm ± 0.1mm, so less 0.1mm, 0.2mm, 0.25mm, 0.3mm, etc. Transparency calibrators of each stage are prepared and provided to the patient in a moving range.

The transparent braces 100 of the present invention can finely move several teeth at a time to fit well, even if the new transparent braces 100 are inserted into the teeth immediately after correction because the teeth are moved while finely moving. The calibration period can be shortened.

At this time, the tooth movement is induced little by little for three weeks, three times a week, and has a rest period for one week. In some cases, the replacement period may be less than a week or even more. If your tooth movements are small, you can go directly to another step without rest. If necessary during this pause, the transparent calibration device 100 of a more rigid material can be fitted to ensure that the calibration state is in between.

After the basic correction condition is input to the dental data, the correction data is corrected by inputting the auxiliary correction condition (S130). Here, the basic calibration conditions refer to the calibration conditions that can be induced by covering the teeth of the transparent calibration body 110 as described above, the auxiliary calibration conditions further improve the calibration force induced by the transparent calibration base 110 Means additional calibration conditions to be added.

In addition, the auxiliary orthodontic conditions include correction conditions that are input in accordance with the color of the teeth of the corrector, extraction, tooth broken state, the size of the teeth, the ratio of neighboring teeth.

2 is an exemplary view showing an example of a transparent calibrator 100 manufactured by applying an auxiliary calibration condition to the method of manufacturing a transparent calibrator of the present invention. As shown, the transparent straightener 100 according to the present invention includes a transparent straightening body 110 that is covered on the teeth of the straightener, a hook 230 coupled to the transparent straightening body 110, and a transparent straightening body 110. The formed open window 117 and the attachment bag 114 for receiving the attachment 220 may be included.

Transparent orthodontic body 110 is formed with a plurality of teeth receiving portion 111 corresponding to the orthodontic teeth of the braces. Although only the transparent calibration body 110 corresponding to the mandible is illustrated in the figure, the transparent calibration body 110 of the maxilla may be configured in the same manner as the mandible.

At this time, the transparent orthodontic body 110 may be formed in accordance with the length of the tooth, or may be formed shorter than the length of the tooth.

The transparent calibration base 110 is formed to meet the basic calibration conditions described above. The button 200 or the attachment 220 may be attached to the surface of the tooth Y to add correction of tooth movement, tilt movement, and rotation movement of the tooth. The button 200 may have an elastic member or a wire extending to the gum to be fixed to the connector to further improve the calibration effect. In this case, an open window 117 for exposing the button 200 to the outside may be formed below the transparent calibration base 110.

Attachment 220 is engaged with the transparent orthodontic body 110 to improve the corrective force by adding an additional force in the direction in which the teeth are to be moved. The transparent calibration base 110 is integrally formed with an attachment pocket 114 for accommodating the attachment 220 therein to improve the corrective force.

At this time, the shape and size of the attachment 220 may be variously formed according to the calibration type, the attachment bag 114 and the attachment 220 may be formed correspondingly. The size of the attachment bag 114 may be formed to be looser than the attachment 220 or may have a size that fits well according to the time of calibration.

On the other hand, the hook 230 may be attached to the dental accommodating portion 111 forward side or lingual side of the transparent calibration base 110. The hook 230 is coupled to the connector is extended to the gum side and then coupled to the elastic member 210a or wire to assist in the correction of teeth.

When inputting the auxiliary calibration condition for the generation of calibration data, the use of the button 200, the attachment 220, the hook 230, etc. is selected in consideration of the type of calibration of the tooth and the current state of the tooth, and accordingly The shape of the open window 117, the attachment bag 114, etc. is designed.

On the other hand, Figure 3 is an exemplary view showing an example of the transparent calibrator 100 manufactured in consideration of the auxiliary calibration conditions and aesthetic conditions in the transparent calibrator manufacturing method of the present invention.

In the dentition of the corrector shown in FIG. 3, discoloration A different from the tooth color is present in the first tooth T1, and there is a loss tooth between the first tooth T1 and the second tooth T2. As a result, a space where a tooth is missing exists. In addition, the third tooth (T3) is a state in which a part of the tooth is lost.

When the transparent braces 100 are worn on the teeth of the straightener, all of the spots A of the first tooth T1, the state of the lost tooth, and the state of no part of the third tooth T3 are exposed to the outside. The corrector may be psychologically attenuated if such an incomplete tooth condition or blemish of the tooth is exposed to the outside during a significant period of correction.

The auxiliary correction condition and aesthetic condition reflects the user's dental condition so that the flaw or incomplete tooth condition of the corrector's teeth is not exposed to the outside during the correction period.

To this end, the colored tooth accommodating part 113 corresponding to the first tooth T1 having the stain A is formed to be non-transparent colored. The color of the colored tooth receiving portion 113 is formed of a tooth color and a gum color similar to the remaining tooth color of the corrector so that the first tooth T1 therein is not exposed when viewed from the outside.

The colored tooth accommodating part 113 may be formed in a discolored tooth, or a region in which a tooth is missing, a tooth whose surface is cracked, or a region corresponding to a broken or lost tooth as shown. In some cases, the entire transparent calibrator 100 may be colored.

The tooth receiving portion 111a corresponding to the region having the lost tooth is coupled to the fake tooth 120 so that the missing tooth is not exposed to the outside. The fake tooth 120 is formed in a shape corresponding to the tooth type of the corresponding area. The fake tooth 120 may be formed of a resin, or may be formed of various materials such as synthetic materials and fixedly coupled to the tooth accommodating part 111a. In addition, when molding using a 3D printer, the fake tooth 120 may also be manufactured integrally with the transparent straightener 100.

Here, the lower portion 121 of the fake tooth 120 forms a rounded shape. 4 is a cross-sectional view illustrating a state in which a transparent brace 100 having a dental accommodating portion 111a having a fake tooth 120 is mounted on a tooth. As shown in the figure, when the transparent braces 100 are mounted on the teeth, the fake teeth 120 are disposed between the first teeth T1 and the third teeth T3, and the lower end 121 of the fake teeth 121 is disposed. It is inserted into the gum to form a natural gum line (B) in which the implant can be placed.

As the fake tooth 120 is disposed between the first tooth T1 and the third tooth T3, a gum line B is formed on the gum, and when the corrector places the implant later, a more esthetic implant is formed. It is possible to form the gum in advance.

In addition, since the fake tooth 120 is inserted into the tooth accommodating portion 111a, there is no effect of improving the aesthetics because the external tooth is not exposed.

In the same manner, a fake tooth part 130 having a size corresponding to the lost part C of the third tooth T3 is coupled to the dental accommodating part 111 corresponding to the third tooth T3 in which a part of the tooth is lost. . As a result, when the transparent braces 100 are worn on the teeth T, the third teeth T3 and the fake teeth 130 are engaged with each other, and thus, the teeth of the perfect shape are exposed to the outside.

In this case, the fake tooth portion 130 may be made or, as described above, the tooth accommodation portion corresponding to the third tooth T3 may be colored to prevent the inside from being exposed.

The fake tooth 120 and the fake tooth portion 113 and the colored tooth receiving portion 113, in addition to the above case, if the ratio of the teeth does not match, the tooth color does not match with the surrounding teeth, the overall color of the teeth If not pretty, it can be reflected in the supplementary calibration conditions by reflecting the intention of the corrector.

In addition, if the upper teeth and lower teeth of the corrector are open bites, the fake teeth that reduce the gap between the upper teeth and the lower teeth are combined inside the transparent brace, or the colored teeth are formed so that the open bites are not exposed to the outside. Can be.

In addition, if there is a space between the teeth in the same way, the space between the teeth of the transparent calibrator 100 may be made to the tooth and gingival color in consideration of the ratio of the tooth shape to make the space appear to be the tooth.

In addition, in the case of the cross bite is formed jagged upper and lower teeth in the same way, it is possible to prevent the cross bite from appearing to the outside by forming a colored tooth accommodating part with an improved shape of the cross bite for aesthetics. For example, if your upper teeth should cover your lower teeth, and you are biting upside down, you can make a fake tooth shape as if your upper teeth cover your lower teeth.

On the other hand, the transparent calibration base 110 is provided with a removal protrusion 115 to facilitate the attachment and detachment of the user. The stripping protrusion 115 is formed to protrude on the buccal side (cheek direction) or lingual side (tongue direction) in the molar direction of the transparent straightening body 110 to facilitate the user to separate the transparent straightener 100 from the teeth.

The stripping protrusion 115 is formed to protrude on the surface of the transparent calibrator 100 as shown in the enlarged cross-sectional view along the line A-A of FIG. At this time, the lower or one side of the removal protrusion 115 may be formed with a finger insertion groove (115a) is inserted into the user's finger. Therefore, when the user wants to separate the transparent braces 100 from the teeth, the user can easily separate by inserting a finger into the finger insertion groove 115a and lifting upwards.

In order to separate the transparent calibrator from the tooth by the stripping protrusion 115, a user may spend time searching for the interface between the transparent calibrator and the gum, and may fix a problem in which the gum is damaged by stabbing the boundary region with a fingernail.

Removal protrusion 115 may be formed from one to four at the top, bottom, left, right of the dental arch can facilitate the attachment and detachment of the transparent calibrator 100 of the user.

On the other hand, the removal protrusion 115 may be provided to protrude a hook that can connect an elastic member (not shown) during calibration.

On the other hand, an identification number 119 indicating a wearing order and a number of the plurality of transparent straighteners 100 is arranged on the lingual side (tongue direction) of the upper and lower jaw anterior teeth (front teeth) of the transparent straightening body 110. The identification number 119 may be a sequence or code for wearing the transparent calibrator 100, a number or a code for identifying a calibrator, and a name.

Identification number 119 is installed on the lingual side of the upper and lower jaw (front tooth) or posterior part that is hard to see when viewed from the outside to improve the aesthetics compared to that provided with the identification number on the occlusal surface (chewing surface) of the conventional upper and lower molars You can.

On the other hand, Figure 5 is an exemplary view showing an example of the use of the transparent calibrator 100 is applied to the auxiliary calibration conditions for the correction of the sunken teeth in the method of manufacturing a transparent calibrator of the present invention.

As shown, when there is an ambush tooth T3 between the first tooth T1 and the second tooth T2, the ambush tooth T3 may be disposed between the first tooth T1 and the second tooth T2. You must free up space. At this time, since the first tooth T1 and the second tooth T2 are empty by the ambush tooth T3, it is aesthetically preferable to fill the empty space during the calibration period.

To this end, as shown in (a) of FIG. 5, the colored tooth accommodating part 113 corresponding to the tooth T is formed in color so that the inside thereof is not visible. Or you can make the magnet itself a tooth color or some other color. And there is arranged a means for inducing faster eruption of the sunken teeth (T3) inside.

A magnet pocket 143 for accommodating the second magnet 140 is disposed in the colored tooth accommodating part 113, and after dissecting the gum, the first magnet 141 is disposed on the ambush tooth T3. In this case, the distance h between the first magnet 141 and the second magnet 140 may be adjusted by adjusting the height of the magnet pocket 143 disposed on the colored tooth accommodating part 113. The distance h between the first magnet 141 and the second magnet 140 may be adjusted according to the depth of the ambush tooth T3. By the magnetic force applied between the first magnet 141 and the second magnet 140, the eruption of the ambush teeth (T3) can be induced more quickly.

Meanwhile, the resin layer 145 may be formed between the ambush tooth T3 and the colored tooth accommodating part 113. The resin layer 145 may artificially make the direction in which the ambush teeth T3 erupt. As the sunken teeth T3 erupt, the upper portion of the resin layer 145 is removed by a predetermined thickness. Since gums above the ambush teeth T3 are removed and the resin layer 145 is disposed, eruption of the ambush teeth T3 is induced more easily, and the space between the first teeth T1 and the second teeth T2 is also increased. Can be adjusted. Here, the resin layer 145 may be replaced with another synthetic material.

Check the roots of the first tooth (T1), the second tooth (T2), and the ambush tooth (T3) by using a CT or panoramic photograph, and check the root of the first tooth (T1), the second tooth (T2), and the ambush tooth (T3). The eruption direction may be adjusted using the resin layer 145 so that the roots are positioned in parallel with each other.

In addition to ambush teeth, other orthodontic teeth are used to enter the correction conditions so that the roots of neighboring teeth are arranged in parallel using CT or panoramic photographs.

On the other hand, Figure 5 (b) is an example of a transparent calibrator is applied another auxiliary calibration condition for the extraction of the sunken teeth (T3). Before the ambush of the ambush teeth T3 is induced by using the magnetic force of the magnet, in FIG. 5B, the first hook 146 is provided on the top of the ambush teeth T3, and the first hook 146 is provided on the surface of the transparent calibration base 110. Two hooks 147 are provided. The first hook 146 and the second hook 147 are connected by the elastic member 149 to induce eruption of the ambush tooth T3.

When the operator has ambushes, the operator enters the basic calibration conditions of the tooth data, and then enters the auxiliary calibration conditions so that the ambush eruption induction means such as a magnet pocket or hook is additionally formed.

On the other hand, Figure 6 is an exemplary view showing a process of adding an auxiliary correction condition when the position of the gum of the corrector is formed lower than the gums of adults.

As shown in (a) of FIG. 6, the gums having a weaker brace or older braces are formed with lower gums than general adults. As a result, a black triangle a region is formed between the neighboring first teeth T1 and the second teeth T2 and are not covered with gums but become empty.

When the transparent straightener 100 is manufactured without additional correction using the teeth data of the straightener, an undercut 112a is formed at a lower portion of the transparent straightening body 110 of the black triangle a to form a very small gap d1. do. When the transparent braces are worn on the teeth of the corrector with the undercuts 112a formed in this way, the undercuts 112a may be disposed on the black triangles (a), and when the transparent braces are subsequently separated from the teeth, a problem may occur. have.

Thus, as shown in (b) of FIG. 6, in the case of a corrector having a black triangle, when forming the tooth models M1 and M2 based on the tooth data, fake gums (b) or fake teeth ( Not shown) to form a transparent calibrator.

When the transparent calibrator is formed in this way, the gap d2 of the black triangle portion is formed to be wider as shown in the sectional view shown below, so that the transparent calibrator can be easily attached and detached.

In this case, the height of the braces is lower than that of the general adult, that is, the auxiliary correction condition can be entered so that the edges of the braces can be formed on the crown side more apart from the gingival edges.

On the other hand, Figure 7 is an exemplary view showing a case in which the byte blocks 160, 165 are formed in the transparent calibrator 100 of the present invention. If the braces of the braces are severe in the incisor of the incisors (the upper teeth cover the lower teeth or vice versa), it is not good to see when correcting. In this case, by forming a bite block in the anterior or posterior of the upper and lower jaw, the improved incisors of the incisor are made to improve the aesthetics and help with orthodontics.

The anterior bite block 160 coupled to the tooth accommodating part 111 covering the anterior teeth is formed in a bar shape continuously coupled to the plurality of anterior teeth. The cross-sectional shape of the front part byte block 160 may be variously formed as shown in FIG. 8.

As shown in (a) of FIG. 8, the pre-byte byte block 160 may be provided in a triangular form, and may be provided in a sharp triangular form as shown in (b) of FIG. 8. In addition, as shown in (c) of Figure 8 may be provided in the form of a square, as shown in (d) of Figure 8 may be provided in the form with a groove below.

In addition, the anterior bite block 160 may be provided in various forms in the range that the teeth in the opposite direction can be contacted and supported.

The posterior bite block 165 coupled to the posterior part 111 ′ may be formed to extend to the occlusal surface (chewing surface) and the buccal side of the tooth as shown in an enlarged view of FIG. 7, or may cover only the occlusal surface. The bite block 165 may be disposed on the occlusal surface of the teeth in order to prevent the transparent calibrator from being broken by the severe teeth. It can also be used to improve the occlusion of the anterior and posterior parts.

9 is an exemplary view showing a modification of the various posterior byte block 165. As shown, the posterior

bite bite blocks

165a, 165b, and 165c may be formed in a flat shape covering the upper part of the occlusal surface of the tooth, and are formed to surround the buccal (cheek side) at the occlusal surface of the tooth (165a), or lingually. A predetermined length may be extended (165b) or may be formed to surround the lingual side (165c). In addition, the posterior bite blocks 165d and 165e may be formed to have a curved surface corresponding to the occlusal surface of the tooth, rather than having a flat upper surface. In this case, one surface of the tooth may be formed to surround (165d) or may be formed to extend to one side (165e).

Here, the pre-byte byte block 160 and the pre-byte byte block 165 may be filled with a filler, or may be formed in an empty form. In the empty form, the portion 161 where the bite block and the transparent brace meet may cover the tooth surface to establish a boundary between the tooth portion and the bite block, or the tooth receiving portion of the device and the internal space of the bite block may be connected without covering the tooth surface. have. In addition, the anterior part byte block 160 and the posterior part byte block 165 may be integrally formed on the transparent calibration base 110, or may be separately manufactured and combined.

On the other hand, Figure 10 is an exemplary view showing a modification of the various transparent braces by the input of the auxiliary correction conditions according to the dental condition of the corrector. In general, the transparent braces 100 are formed to cover all of the pure surface l, the occlusal surface o and the lingual surface n of the tooth T, as shown in FIG.

However, when expansion of the arch is necessary, the transparent braces 100b may be formed to extend in the form of covering the palate (palate) in the upper jaw, or may be formed in the form of covering the lingual in the lower jaw. That is, as shown in (b) of Figure 10 may be provided with an extended surface 170 extending from the lower portion of the lingual surface (n) of the tooth (T) toward the lingual side.

Meanwhile, as shown in FIG. 10C, the transparent brace 100c exposes the pure surface l of the tooth T to the outside and only the occlusal surface o and the lingual surface n of the tooth T. It may be formed in a covering form. In this case, the extension surface 170 may be provided to reinforce the corrective force.

In addition, as shown in FIG. 11, the anterior portion (front teeth) of the transparent calibrator 100 may be formed in a shape in which a pure surface ℓ is drilled. That is, when viewed from the front, some teeth may be formed in a form in which only the canine and molar parts are wrapped without the transparent braces. As a result, some of the teeth are not accommodated in the transparent calibration base and are formed in a more aesthetic form exposed to the outside. At this time, the occlusal surface o can be removed together with the pure surface l.

On the other hand, Figure 12 is a form manufactured by adding only the aesthetic condition to the basic calibration conditions in the manufacture of the transparent calibrator. In this case, various tattoos 180 may be attached to the pure surface of the transparent calibrator 100a, an image 181 may be painted, or a decorative member 183 such as cubic may be attached to add aesthetics.

In this case, the transparent braces 100a may be formed to be different from each other in the color of the tooth accommodation portion. The transparent calibrator 100a may be used to reveal the personality of the corrector, or in some cases, may be used as a one-time use for use in a play or a movie.

As described above, the method for manufacturing a transparent calibrator according to the present invention and the transparent calibrator manufactured by the present invention assist in improving or improving aesthetics in addition to basic calibration conditions for applying orthodontic force based on the teeth data of the braces.
