Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a clear-

The present invention relates to a method of manufacturing a transparent calibrator, and more particularly, to a method of manufacturing a transparent calibrator capable of reducing pain, improving corrective power, and improving esthetics during a calibration period.

In general, non-uniform dentition, malocclusion, and facial protrusion are caused by inadequate growth of teeth and oral and maxillofacial surfaces due to developmental abnormalities of the teeth and jaws, bad habits or genetics affecting teeth, and the like. The dental and oral structures are factors that determine the human impression, and they cause the degradation of the food pulverizing function, and therefore interest in orthodontic treatment is increasing day by day.

Orthodontic treatment uses the property that the tooth moves when it receives some force. The most widely used method for orthodontic treatment is a fixed treatment method in which a bracket is attached to a tooth and the teeth are moved using the elasticity of a wire or an elastic band. Brackets are usually made of metal, but there are conspicuous disadvantages during treatment.

To overcome these disadvantages, a transparent calibration method has been proposed. Transparent correction is a procedure in which a transparent orthodontic appliance that changes step by step from the state of the tooth before correction to the state of the tooth desired to be corrected is prepared, and the tooth is corrected by changing the tooth.

Specifically, the procedure using the transparent correction apparatus was developed in 1997 and is a tooth correction apparatus developed by Align Technology, Inc. of the United States under the name of "Invisalign System", and US Pat. No. 5,975,893 And 6,217,325, which are incorporated herein by reference. The "Invisalign System" cuts the teeth one by one on a computer by using a special program of three-dimensional scan data on the teeth, creates 20 to 30 pairs of models in a step-by-step manner to finally move the teeth through virtual simulation, Transparent plastic frames that can move teeth by model are made and distributed to patients.

The feature of "Invisalign System" is to move the tooth to be calibrated little by little by inserting a prepared series of plastic orthodontic appliance into the teeth step by step, and the plastic frame is made of transparent material, Because it is not admitted, it can greatly contribute to the daily social life of the orthodontic patient, and the patient can remove the orthodontic device as needed.

However, even though the transparent calibrator has the advantages described above as compared with the fixed calibrator using the bracket described above, the pain applied to the patient is small.

That is, in this transparent corrective treatment, because the nature of the material for securing the esthetics induces the tooth arrangement using a hard sheet, the transparent correction device is hard due to the nature of the hard material, so that the pain applied to the patient is not so small.

In addition, despite the many advantages of a transparent calibrator, it is less accurate than a stationary calibrating device if the device does not fit well when the tooth is moved, making it difficult for the device to settle and desirable tooth movement.

On the other hand, in the teeth of the proofreaders, the surface of the tooth is discolored, the teeth are empty, the teeth are spaced apart, the teeth are broken, the shape is not so good or malformed, or the upper and lower anterior teeth If it is open, the teeth may be jagged by cross-bite. In this case, even if the calibrator is worn by a transparent calibrator, the present state of the teeth is exposed to the outside, which is not aesthetically pleasing.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems, and to provide a method of manufacturing a transparent calibrator capable of quickly exhibiting a tooth correcting effect while reducing the pain of a calibrator.

For a better understanding of the present invention, a preferred embodiment of the present invention will be described with reference to the accompanying drawings. The embodiments of the present invention may be modified into various forms, and the scope of the present invention should not be construed as being limited to the embodiments described in detail below. The present embodiments are provided to enable those skilled in the art to more fully understand the present invention. Therefore, the shapes and the like of the elements in the drawings can be exaggeratedly expressed to emphasize a clearer description. It should be noted that in the drawings, the same members are denoted by the same reference numerals. Detailed descriptions of well-known functions and constructions which may be unnecessarily obscured by the gist 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 in the figure, a method of manufacturing a transparent calibrator according to the present invention includes a step (S110) of acquiring tooth data by scanning a tooth of a calibrator three-dimensionally, a step (S120) of inputting calibration conditions for calibrating a tooth of a calibrator, (S130) of inputting auxiliary calibration conditions to be further corrected in addition to the basic calibration condition, inputting an aesthetic condition to be aesthetized to the tooth of the calibrator during the calibration period (S140), a basic calibration condition and a supplementary calibration condition And shaping a transparent calibrator corresponding to the calibration data including all of the aesthetic conditions (S150).

The tooth data of the proofreader can be obtained by directly scanning the tooth of the current state of the proofreader through a 3D scanner, by acquiring the tooth bone through the impression of the proofreader, or by using radiation equipment such as CT or panorama.

The tooth data thus obtained is input to the three-dimensional modeling software, and the teeth that need to be corrected among the teeth of the proofreader are gradually moved and rearranged to the desired tooth arrangement by reflecting the basic correction condition, the auxiliary correction condition and the aesthetic condition of the tooth A plurality of teeth correction data capable of giving a sense of aesthetics are generated during the correction period. Then, a tooth molding model is formed based on the generated tooth calibration data, the transparent sheet is vacuum-extruded to form a transparent calibrator, or the transparent calibrator can be directly molded through a three-dimensional printer. The aesthetic parts required by the aesthetic condition can be integrally coupled to the inside of the transparent calibrator, and in some cases, attached to the outside of the transparent calibrator.

On the other hand, there may be occasions where the secondary correction conditions and aesthetic conditions of the teeth are related to each other or the classification is ambiguous. In this case, it is possible to input the teeth data without distinction between the auxiliary correction condition and the aesthetic condition of the tooth, so that the aesthetic sense and the correction force can be given together.

Here, the basic calibration condition of the tooth referred to in the input step (S120) of the basic calibration condition refers to the calibration conditions required for the tooth requiring correction among the teeth of the proofreader. The basic calibration conditions can be rotation correction to rotate the teeth, correction of the teeth that have been pinched or compressed, correction of the tooth axis to straighten the formed tooth axis, and the like. In addition, the basic calibration conditions include various orthodontic and orthodontic correction types such as reverse, open, occlusion, amblyopia, and malocclusion.

Calibration data for a plurality of transparent calibrators is generated so that the basic calibra- tion conditions can be input and moved to a smaller extent gradually from the current tooth state to the desired state.

The transparent straightener 100 is inserted into the teeth and applies a correcting force in a direction in which the teeth should be corrected. 2 is an exemplary diagram showing an example of the transparent calibrator 100 of the present invention.

The transparent straightener 100 has a tooth receiving portion 111 formed in the transparent straightener main body 110 inserted into a tooth to correspond to a tooth shape of a tooth. At this time, the transparent straightener 100 according to the present invention does not need to move excessively at once and is formed so as to apply a slight force to the periodontal ligament of a tooth desired to move in a state in which it is formed to fit well with the teeth. Thereby directly inducing bone resorption and accelerating tooth movement.

Conventional invasive line and occlusion can cause pain to the patient because it induces a large range of motion, 0.5 to 1 mm at a time. If strong pressure persists, indirect absorption will occur and tooth movement will be slow in 7-14 days and accompanied by pain. In addition, since the correction width between the transparent tooth calibrator of the next step and the transparent tooth calibrator of the previous step is large, a longer time is required for the transparent tooth calibrator of the next step to be matched to the tooth. The next step is to fit the transparent tooth bracket quickly, it does not fit well and the calibration is not as good as desired. In this case, it may be necessary to reproduce the transparent correction device by reopening the impression bone in the middle of the calibration.

On the other hand, the transparent straightener 100 of the present invention applies a weak pressure continuously to induce direct absorption so that the tooth movement can be rapidly displayed within one to two days. In this case, the patient feels little pain. In this manner, a transparent calibrator 100 of the next stage is manufactured in a form that is well suited to the current tooth condition, so that the calibrations proceed smoothly without pain.

Since the transparent orthodontic appliance 100 of the present invention induces direct bone resorption, the average periodontal ligament space is 0.25 mm ± 0.1 mm, so that the size of the periodontal ligament is 0.1 mm, 0.2 mm, 0.25 mm, Transparent calibrators at each step are prepared and delivered to the patient as a range of motion.

Since the transparent calibrator 100 according to the present invention performs the calibration while finely moving the teeth, even when the new transparent calibrator 100 is inserted into the tooth immediately after the calibration, it is possible to precisely move the plurality of teeth at once, The calibration period can be shortened.

At this time, basically, tooth movement is induced little by three times for one week, for three weeks, and there is a rest period for one week. In some cases, the timing of device replacement may be less than a week or more. If the amount of tooth movement is small, you can go straight to another step without a break. If necessary in this rest period, a transparent calibrator 100 of a more rigid material can be interposed to ensure that the calibrated state is in between.

After the basic calibration condition is inputted to the tooth data, the correction data is corrected by inputting the sub-calibration condition (S130). Here, the basic calibration condition means calibration conditions that can be derived by putting the transparent corrective apparatus main body 110 described above on the teeth of the corrective person, and the auxiliary correction condition is a condition in which the correction force induced by the transparent corrective apparatus main body 110 is improved The calibration conditions are added additionally.

The supplemental calibration conditions also include calibration conditions entered in accordance with the corrector's tooth color, tooth extraction, tooth breakage, tooth size, and ratios of neighboring teeth.

FIG. 2 is an exemplary view showing an example of the transparent calibrator 100 manufactured by applying the supplementary calibration condition to the transparent calibrator manufacturing method of the present invention. As shown in the drawing, the transparent straightener 100 according to the present invention includes a transparent straightener body 110 which is placed on the teeth of a corrective person, a hook 230 coupled to the transparent straightener body 110, An open window 117 formed therein, and a deposit bag 114 for receiving the deposit 220.

The transparent corrective apparatus main body 110 has a plurality of tooth receiving portions 111 corresponding to the teeth of the proofreader. Although only the transparent correcting apparatus main body 110 corresponding to the mandible is shown in the figure, the transparent corrective apparatus main body 110 of the upper and lower maxillary can also be configured in the same manner as the mandible.

At this time, the transparent straightener main body 110 may be formed to match the length of the teeth, or may be formed to be shorter than the teeth by a predetermined length.

The transparent calibrator main body 110 is formed to meet the basic calibration conditions described above. A button 200 or an attachment 220 may be attached to the surface of the tooth Y to add correction of tooth movement, inclination movement, and rotational movement of the tooth. The elastic member or the wire may be extended to the button 200 and may be fixed to the connector to improve the correcting effect. At this time, an open window 117 for exposing the button 200 to the outside may be formed under the transparent straightener main body 110.

The attachment 220 engages the clear straightener body 110 and adds additional force in the direction in which the teeth are to be moved to improve the corrective force. The transparent bracket main body 110 is integrally formed with a deposit bag 114 for accommodating the deposit 220 therein to improve the correction force.

At this time, the shape and size of the attachment 220 may be variously formed according to the type of the correction, and the attachment bag 114 and the attachment 220 may be formed correspondingly. The size of the attachment bag 114 may be formed looser than the attachment 220 or may be formed to a perfect size depending on the correction timing.

The hook 230 may be attached to the side of the tooth receiving portion 111 of the transparent straightener main body 110. The hook 230 is connected to the connector and extends to the side of the gum, and is then coupled to the elastic member 210a or wire to assist in correcting the teeth.

When the auxiliary correction condition is input for generating the calibration data, whether to use the button 200, the attachment 220, the hook 230 or the like is selected in consideration of the type of correction of the teeth and the current state of the teeth, The open window 117, the attachment bag 114, and the like are designed.

Meanwhile, FIG. 3 is an exemplary view showing an example of a transparent calibrator 100 manufactured by considering a supplementary calibration condition and an aesthetic condition in a transparent calibrator manufacturing method of the present invention.

In the dentition of the proofreader shown in Fig. 3, the first tooth T1 has a discoloration A different from the tooth color, and there is a loss between the first tooth T1 and the second tooth T2. Thereby, a space in which the teeth are missing is present. The third tooth T3 is in a state in which a part of the tooth has been lost.

When the transparent calibrator 100 is worn on the dentition of such a corrector, the spots A of the first teeth T1, the state of the lost teeth, and the state where the third teeth T3 are not partly exposed are all exposed to the outside. If such incomplete tooth condition or tooth flaws are exposed outside during a significant period of correction, the proofreader may be psychologically shrinking.

The supplementary calibration and aesthetic conditions reflect the user's tooth condition so that the defect of the corrector's tooth or incomplete tooth condition is not exposed during the calibration period.

For this purpose, the colored tooth receiving portion 113 corresponding to the first tooth T1 having the stain A is formed in a color that is not transparent. The color of the colored tooth accommodating portion 113 is formed in a tooth color and a gum color similar to the color of the remaining teeth of the proofreader, so that the first tooth T1 inside is not exposed when viewed from the outside.

The colored tooth accommodating portion 113 may be formed in a region corresponding to a discolored tooth or a region where teeth are missing, a surface-cracked tooth, or a tooth where a part of the tooth is broken or lost as shown in the figure. In addition, the entire transparent calibrator 100 may be colored as a whole.

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

Here, the lower portion 121 of the false teeth 120 forms a rounded shape. 4 is a cross-sectional view showing a state in which a transparent straightener 100 provided with a tooth receiving portion 111a in which a false tooth 120 is formed is mounted on a tooth. As shown in the drawing, when the transparent straightener 100 is mounted on the teeth, a false tooth 120 is disposed between the first tooth T1 and the third tooth T3, and the lower end 121 of the false tooth 121 Thereby forming a natural gum line B into which the implant can be inserted.

The gum line B is formed on the gum by arranging the false teeth 120 between the first tooth T1 and the third tooth T3 so that a more esthetic implant The gingiva can be formed in advance.

In addition, since the pseudo tooth 120 is inserted into the tooth receiving portion 111a, it is not revealed that there is no tooth on the outside, thereby improving the esthetics.

A false tooth portion 130 having a size corresponding to the lost portion C of the third tooth T3 is also coupled to the tooth receiving portion 111 corresponding to the third tooth T3 in which a part of the tooth has been lost . As a result, when the transparent straightener 100 is worn on the tooth T, the third tooth T3 and the false tooth part 130 are engaged with each other, and the tooth is completely exposed.

In this case, a false tooth portion 130 may be formed, or the tooth receiving portion corresponding to the third tooth T3 may be colored as described above to prevent the inside from being exposed.

In the case where the teeth ratio is not appropriate in addition to the above-mentioned cases, when the teeth color does not match the surrounding teeth, the tooth color of the teeth 100, If not, it can be reflected in the supplementary calibration conditions by reflecting the will of the proofreader.

In addition, if the upper and lower teeth of the proofreader are open bytes, the false teeth that reduce the gap between the upper teeth and the lower teeth may be coupled to the inside of the transparent bracket, or a colored tooth receiving portion may be formed to prevent the open bytes from being exposed .

If there is a space between the teeth in the same manner, the space between the teeth of the transparent straightener 100 may be made into teeth and gingiva in consideration of the ratio of tooth shape so as to make teeth appear as teeth.

In addition, in the case of a cross-bite in which the upper teeth and the lower teeth are formed in the same manner in a similar manner, the cross-bite is improved for the aesthetics, so that the colored tooth receptacle is formed so that the cross bite is not exposed to the outside. For example, an upper teeth should cover the lower teeth, but if they are upside down they may form a false tooth shape as if the upper teeth are covering the lower teeth.

On the other hand, the transparent straightener main body 110 is provided with a detaching projection 115 that facilitates detachment and attachment of a user. The detaching projection 115 protrudes in the cheek side or lingual side (tongue direction) in the molar direction of the transparent straightener body 110 so that the user can easily separate the transparent straightener 100 from the teeth.

The detaching projection 115 is formed so as to protrude from the surface of the transparent straightener 100 as shown in an enlarged sectional view taken along the line A-A in FIG. At this time, a finger insertion groove 115a into which the user's finger is inserted may be formed on the lower or one side of the detachment protrusion 115. Accordingly, if the user desires to remove the transparent straightener 100 from the teeth, the user can insert the finger into the finger insertion groove 115a and lift it upward to easily separate the finger.

In order to separate the conventional transparent calibrator from the tooth by the detachment protrusion 115, the user can spend time searching for the interface between the transparent calibrator and the gum and solve the problem of the gum being damaged by piercing the boundary area with the nail.

The detachment protrusions 115 are formed on the upper, lower, left, and right sides of the dental arch 1 to 4, respectively, so that the user can easily detach and attach the transparent straightener 100.

On the other hand, the detaching projection 115 may be provided with a hook protruding to connect an elastic member (not shown) at the time of calibration.

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

The identification number 119 is provided on the lingual side of the superior and inferior anterior teeth (front teeth) or the posterior teeth that are not visible when viewed from the outside, so that the esthetic sense is improved more than the conventional art in which the identification numbers are provided on the occlusal surfaces (chewing faces) .

5 is an exemplary view showing an example of the use of the transparent calibrator 100 to which the sub-calibration conditions for calibrating the ambulation are applied in the method of manufacturing the transparent calibrator of the present invention.

As shown in the figure, when the implanted tooth T3 is present between the first tooth T1 and the second tooth T2, the implant T3 may be disposed between the first tooth T1 and the second tooth T2 There must be enough room. At this time, since the gap between the first tooth T1 and the second tooth T2 is absent due to the impact T3, it is esthetically preferable to fill the empty space during the calibration period.

For this purpose, as shown in FIG. 5 (a), the colored tooth receiving portion 113 corresponding to the tooth T is colored to prevent the inside from being seen. Alternatively, the color of the magnet itself can be made into teeth or other colors. And a means for inducing eruption of the implants (T3) more quickly is arranged therein.

A magnet pocket 143 in which the second magnet 140 is received is disposed in the colored tooth accommodating portion 113 and the first magnet 141 is disposed on the upper portion of the implanted tooth T3 after cutting the gum. The distance h between the first magnet 141 and the second magnet 140 can be adjusted by adjusting the height at which the magnet bag 143 is disposed in the colored tooth accommodating portion 113. The distance h between the first magnet 141 and the second magnet 140 can be adjusted according to the depth at which the impact T3 is embedded. The eruption of the impacted tooth T3 can be induced more quickly by the magnetic force applied between the first magnet 141 and the second magnet 140. [

On the other hand, a resin layer 145 can be formed between the impacted tooth T3 and the colored tooth receiving portion 113. The direction in which the apposite T3 is erupted by the resin layer 145 can be made artificially. The upper portion of the resin layer 145 is removed by a certain thickness as the apposite T3 is erupted. Since the gums on the upper portion of the appendix T3 are removed and the resin layer 145 is disposed on the lower surface of the first tooth T1, eruption of the apposition T3 is more easily induced, . Here, the resin layer 145 may be replaced with other synthetic materials.

The root of the first tooth T1, the second tooth T2 and the impacted tooth T3 is confirmed by CT or a panoramic photograph or the like and the root of the first tooth T1 and the second tooth T2 and the impacted tooth T3 The erosion direction can be adjusted using the resin layer 145 so that the roots are positioned parallel to each other.

This is because the correction conditions are input so that the tooth roots of neighboring teeth are arranged in parallel by using CT or panoramic photographs when not only the implants but also other orthodontic teeth are corrected.

Meanwhile, FIG. 5 (b) shows an example of a transparent calibrator to which another sub-calibration condition for eruption of the impacted tooth T3 is applied. 5 (b), the first hook 146 is provided on the upper portion of the apposition T3, and the first hook 146 is provided on the surface of the transparent rectifier main body 110. In this case, 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 impacted tooth T3.

The operator inputs the basic calibration conditions of the tooth data when the proofreader has the implants, and then inputs the supplemental correction conditions so that additional means of inducing the implanted blades, such as a magnet bag or hook, is formed.

Meanwhile, FIG. 6 is an exemplary diagram showing a process of adding a sub-calibration condition when the position of the gum of the calibrator is formed lower than the gums of ordinary adults.

As shown in FIG. 6 (a), a weak gum corrector or an old-age proofreader has a gum position lower than that of ordinary adults. As a result, a region of the black triangle (a) in which the neighboring first tooth T1 and the second tooth T2 are not covered with the gum but becomes empty is formed.

When the transparent calibrator 100 is manufactured without any correction using tooth data of the calibrator, an undercut 112a is formed under the transparent straightener main body 110 of the black triangle (a) portion so that the interval d1 is very narrow. do. When the transparent calibrator is worn on the teeth of the calibrator in the state that the undercuts 112a are formed, the undercuts 112a are disposed on the black triangle a so that the teeth may be pulled out when the transparent calibrator is separated from the teeth have.

As shown in FIG. 6 (b), in the case of a proofreader having a black triangle, when the tooth models M1 and M2 are formed on the basis of the tooth data, a false tooth g Not shown), and a transparent calibrator is formed.

When the transparent calibrator is formed as described above, the clearance d2 of the black triangle portion is formed to be wide as shown in the sectional view at the bottom, so that the transparent calibrator can be easily attached and detached.

In the case of these gingivae going down to the root, supplemental calibration conditions can be entered so that the height of the transparent calibrator is lower than that of normal adults, ie, the margin of the transparent calibrator falls off the gingival margin and forms more on the crown side.

7 is an exemplary view showing the case where the byte blocks 160 and 165 are formed in the transparent rectifier 100 of the present invention. If the dentist's dentition is severe on the occipital crown (when the upper teeth are severely covered by the lower teeth, or vice versa), it is not good for calibration. In this case, a bite block is formed on the anterior and posterior parts of the maxilla and mandible to improve the aesthetic sense by making an improved frontal incarnation, which also helps in orthodontics.

The anterior tooth block 160, which is coupled to the tooth receiving portion 111 covering the anterior teeth, is formed in a bar shape that is continuously connected to a plurality of anterior teeth. The cross-sectional shape of the anterior tooth block 160 may be variously formed as shown in FIG.

As shown in FIG. 8 (a), the anterior tooth block 160 may be provided in a triangular shape or a sharp triangular shape as shown in FIG. 8 (b). 8 (c), or may be provided with a groove at the bottom as shown in FIG. 8 (d).

In addition, the anterior tooth block 160 may be provided in various forms within a range in which teeth in opposite directions can be held in contact with each other.

The posterior bite block 165 coupled to the posterior portion 111 'may be formed so as to extend to the side of the oral cavity of the teeth (chewing face) as shown in FIG. 7, or to cover only the occlusal surface. This byte block 165 may be placed on the occlusal surface of the tooth to prevent breakage of the transparent calibrator by severely deformed proofreaders. It can also be used to improve occlusion of the anterior and posterior teeth.

FIG. 9 is an exemplary diagram illustrating a variation of various posterior byte blocks 165. As shown, the posterior bite blocks 165a, 165b, and 165c may be formed in a flat shape covering the upper part of the occlusal surface of the teeth, and may be formed to enclose the cheek side (165a) A certain length may be elongated (165b) and the lingual side may be formed (165c). Further, the posterior block blocks 165d and 165e may be formed to have a curved surface corresponding to the occlusal surface of the tooth without the top surface being flat. In this case as well, one side of the teeth may be formed (165d) and extended to one side (165e).

Here, the former block block 160 and the latter block block 165 may be filled with a filler material or may be formed in an empty form. In the empty form, the portion 161 where the byte block and transparent corrector meet may form a boundary between the tooth region and the bite block by covering the tooth surface, or the tooth receiving portion of the device may be connected to the inner space of the bite block have. In addition, the anterior tooth block 160 and the posterior block 165 may be integrally formed with the transparent straightener body 110, or they may be separately manufactured and combined.

Meanwhile, FIG. 10 is an exemplary view showing a modification of various transparent calibrators by inputting auxiliary correction conditions according to the tooth condition of the proofreader. In general, the transparent corrector 100 is formed so as to cover both the face 1, the occlusal surface o and the lug side n of the tooth T as shown in Fig. 10 (a).

However, if the arch is to be expanded, the transparent straightener 100b may be formed to extend over the upper part of the palate (palate) or cover the lingual side of the mandible. That is, as shown in FIG. 10 (b), the elongated surface 170 extending from the lower side of the lug side n of the tooth T toward the lingual side may be provided.

10C, the transparent calibrator 100c exposes the pure surface 1 of the tooth T to the outside, and only the occlusal surface o and the snow surface n of the tooth T Or the like. In this case, the extension surface 170 may be provided to enhance the corrective force.

11, an anterior portion of the transparent straightener 100 may be formed in a shape in which a face l is opened. That is, when viewed from the front, some teeth may be formed in such a form that the transparent braces are not wrapped but only the canines and molar portions are wrapped. Thereby, some teeth are formed in a more aesthetic form that is not accommodated in the transparent straightener body but exposed to the outside. At this time, the occlusal surface o can be removed together with the face l.

On the other hand, FIG. 12 shows a form in which only the aesthetic condition is added to the basic calibration condition at the time of manufacturing the transparent calibrator. In this case, various tattoos 180 may be attached to the transparent surface of the transparent straightener 100a, the image 181 may be painted, or a decoration member 183 such as cubic bezel may be attached to add a sense of beauty.

Here, the transparent calibrator 100a may be formed so that the hues of the tooth receiving portions are different from each other. The transparent corrector 100a may be used to reveal the personality of a calibrator or may be used for a one-time use for use in a theater or a movie in some cases.

As described above, according to the method of manufacturing a transparent calibrator according to the present invention and the transparent calibrator manufactured by the method, in addition to the basic calibration conditions for applying the correction force based on the tooth data of the calibrator, it is possible to improve the correction force, Calibration conditions and aesthetic conditions are further taken into account.
