Here, the reception management unit 210 may authenticate the access from each dentist through a process of logging in and authenticating an ID and a password for each dentist.

The correction processing unit 220 preprocesses the 3D scanner 221 for 3D scanning the tooth pattern of the patient among the received tooth data and the current tooth data of the 3D scanned patient, and reflects the instructions of the attending physician to reflect the current tooth data. It may be configured to include a dental orthodontic module 222 to generate the orthodontic tooth data by processing.

Here, when the tooth data includes current tooth data of the 3D scanned patient, the configuration of the 3D scanner may be excluded from the correction processor.

Here, the transparent material should be made of a non-toxic bio-friendly material as inserted into the tooth, Tupan which is a transparent bio-friendly material can be used.

Hereinafter, a method of manufacturing a transparent straightener according to a preferred embodiment of the present invention will be described.

2 is a flowchart schematically showing a method of manufacturing a transparent calibrator according to a preferred embodiment of the present invention.

Referring to Figure 2, the transparent braces manufacturing method according to the present invention receives and receives the dental data of the patient from the dental terminal (S110).

Here, the attending physician of the dentist may access the ID / password when the member registration is registered from the orthodontic management server. If the member registration is not registered, the dentist may set the personal information and the ID / password to register the membership and access the same.

Here, the personal information may include information for identifying a dentist such as a dentist's name, a dentist's name, and a dental address.

The patient's tooth data should basically include the patient's tooth bone, and as shown in FIG. 3, data including the patient's X-ray photograph and front and side photograph information for comparison with the doctor's correction instruction and before and after correction. It may be received in the reception management unit in the form of a format.

When the dental data of the patient is received from the dental terminal, the tooth bone of the patient is scanned through the 3D scanner. (S120)

Subsequently, the orthodontic module acquires the current dental data D0 of the patient as shown in FIG. 4 through preprocessing (S130).

Here, the preprocessing means a process of removing an unnecessary area of the 3D scanned data and automatically matching a condition for setting a resolution and a size.

Subsequently, the dental orthodontic module generates the orthodontic tooth data by correcting the current tooth data.

More specifically, first, distinguish the maxilla and the mandible of the current dental data.

Basically, since the teeth are composed of the maxilla and the mandible, it is necessary to distinguish the maxillary and the mandible for the movement of individual teeth, and distinguish the maxillary and the mandible as shown in FIG. do.

And position the current dental data in which the maxillary and mandibular are distinguished.

Since the scanned current tooth data is scanned at an inclined angle, the positioning is performed as shown in FIG. 6 for accurate alignment of the teeth.

The orthodontic module then distinguishes between the tooth and the gum region.

Since the current tooth data of the 3D scanning patient can clearly distinguish the tooth and the gum region, the tooth and the gum region can be distinguished as shown in FIG. 7 through image boundary detection or selection designation.

And when the teeth and gum areas are distinguished, they separate between the teeth that need correction.

In case of teeth that need correction, the position of the teeth must be displaced through the process of enlarging, rotating, and returning the teeth. Therefore, a space for moving the teeth that needs to be moved for correction is required. Since it is difficult to distinguish between the teeth in the present form, the teeth needing correction are distinguished as shown in FIG.

When the teeth are distinguished as described above, reference information for each individual tooth is designated.

Here, the reference information is based on the average height of the distal and the tooth, which is located far from Mesial, which is located close to the tongue of both ends of the tooth, based on the virtual arch line of the entire tooth as shown in FIG. 9. And a FAP which is a point located at the center of the tooth with respect to the formed virtual arch line.

In addition, as shown in FIG. 10, axes for all teeth are set to include designated axis information. As described above, the reference information is set, and the reference information is set for each tooth and mapped to the tooth name.

As described above, when reference information of a tooth is set, displacement, rotation, and return may be individually controlled.

When the reference information is designated as described above, the teeth needing correction are moved through expansion, rotation, and return operations to generate orthodontic tooth data.

The orthodontic tooth data is generated by correcting the tooth to be aligned with the virtual arch line by expanding, rotating and returning the tooth that needs to be corrected based on the virtual arch line generated when setting reference information.

The orthodontic tooth data is data generated by moving a tooth to a predetermined position through a process of expanding, rotating, and restoring a tooth that needs to be corrected. Tooth data can be formed.

Here, the steps of expanding, rotating, and returning the tooth may be subdivided according to the condition of the tooth and the number, location, etc. of the tooth to be corrected, and in the case of minor tooth correction, the final corrective tooth data may be formed. The steps necessary for this may vary from patient to patient.

The expansion of the teeth means protruding the teeth to secure a space to rotate the teeth, the rotation of the teeth means to move the teeth up and down, left and right four-axis to the position that needs to be corrected, the return of the teeth is expanded It means to move the tooth to the original position after correcting the rotation.

Here, the expansion of the tooth is a necessary process when the space for moving the tooth is not necessary. If the tooth movement space cannot be secured only by the expansion of the tooth, a stripping process of grinding the tooth to reduce the width of the tooth is further performed. May be included.

Hereinafter, a method of generating orthodontic tooth data will be described through more specific examples.

11 is a flowchart specifically showing a method for generating orthodontic teeth data according to an exemplary embodiment of the present invention.

Referring to FIG. 11, first, a tooth reference line is inserted into a tooth as shown in FIG. 12A.

Here, the tooth reference line may be composed of an arch line in the case of an ideal tooth arrangement.

Next, as shown in FIG. 12B, a tooth to be moved is selected. (s220)

Here, the tooth that needs to be moved may be extracted from a degree deviated from the tooth reference line and a degree distorted from the tooth axis.

Then, the width of the tooth to be moved is compared with the width of the tooth reference line as shown in FIG. 12C.

More specifically, the teeth are separated and the width of each tooth is measured using Mesial and Distal among the reference information.

As described above, when the width of each tooth is measured and the distance between the teeth is extracted, it is determined whether the space to which the tooth to move is secured by comparing the size of the tooth with the expandable tooth width according to the tooth reference line.

In this case, when the size of the tooth to be moved is larger than the reference tooth size according to the tooth reference line, the tooth to be moved and the teeth on both sides are expanded together to secure a space. (S240) The movement distance at the time of tooth expansion is limited to 1 mm per time.

Table 1 below is a comparison of the actual tooth width and the available tooth width according to the tooth baseline.

TABLE 1

As can be seen from Table 1 and FIG. 12D, in the case of tooth 3, since the tooth size is required because the actual tooth size (4.76) is larger than the tooth size (4.6) according to the tooth baseline, the tooth as shown in FIG. Expand.

Here, in some cases, when a space for moving only by tooth expansion is not secured, a stripping process may be included to reduce the width of the tooth in order to secure space.

When the tooth is expanded as described above, the width of the tooth to be moved is smaller than the width of the tooth that can be secured according to the tooth reference line, so that the space to be moved is determined again. If not, the step S240 is repeated.

In addition, when the space is secured because the width of the tooth to be moved is smaller than the width of the tooth according to the tooth reference line, the tooth expansion step may be omitted, and as shown in FIG. (s250)

If the tooth to be moved does not match the direction of the tooth reference line, the tooth is rotated based on the FAP as shown in FIG. 12G. Here, the rotation of the teeth to be moved is limited so that the movement amount per one step is 1 mm or less.

When the tooth is rotated as described above, it is again checked whether the tooth to be moved and the tooth reference line are coincident, and if it does not match as shown in FIG.

When the tooth to be moved through the tooth rotation as described above coincides with the direction of the tooth baseline, it is checked whether the tooth to be moved coincides with the tooth baseline (s270).

Here, when the tooth is rotated and the tooth to be moved does not coincide with the tooth reference line, the tooth is returned (s280). When the tooth is returned, the amount of movement per step is limited to 1 mm or less.

Thereafter, if the teeth to be moved are checked to match with the tooth baseline, and if they do not match, the process is repeated in step S280, and when the teeth are moved, the calibration is completed as shown in FIG. 12I.

Figure 13 schematically illustrates orthodontic tooth data divided into a number of stages in accordance with the present invention.

Referring to FIG. 13, the present embodiment shows that the current tooth data is generated as the final corrected tooth data through a total of seven steps. FIG. 13A shows the current tooth data before the correction.

13B-13D show orthodontic tooth data of an expanding step to rotate the tooth in the correcting first to third steps.

The reason why the tooth expansion step is divided into three stages is that the tooth is limited in the distance that can be moved in one step.

FIG. 13E shows orthodontic tooth data of a step of rotating the tooth extended to the fourth step of orthodontics. FIG.

13F to 13H illustrate corrective tooth data of the step of returning the tooth rotated in the corrected fifth to seventh steps to the original position, and the corrected tooth data of the seventh step is the final corrected tooth data.

FIG. 13I shows a comparison of current tooth data before correction and final correction tooth data after correction. FIG.

When the orthodontic tooth data is generated as described above, the simulation unit generates data for comparing the contour change of the patient before and after the correction. (S150)

More specifically, as shown in FIG. 14A, the side picture of the patient is matched with the X-ray picture, and the profile information is generated by connecting the reference points of the facial skeleton in the state where the side picture and the X-ray picture of the patient are matched. Map current tooth data as shown in 14b.

As described above, if the current dental data is changed from the corrected dental data to the corrected dental data from the side photo, the X-ray photograph, and the current dental data, the contour of the patient is changed by the corrected dental data as shown in FIG. 14C. Calibration data is generated to confirm.

When the simulation unit generates comparison data before and after correction, as shown in FIG. 15, the correction data including the comparison data before and after correction and the correction tooth data are transmitted to the dental terminal that has requested the correction to undergo the confirmation process of the attending physician and the patient. (S160)

Here, if there is a correction correction of the orthodontic tooth data, the attending physician may request correction of the correction through the dental terminal (S170), in which case it is fed back to the step S140.

When the diagnosis of the orthodontic tooth data is confirmed, a tooth mold for each of the orthodontic tooth data divided into the plurality of steps is manufactured.

When orthodontic tooth data is generated in seven steps in the above embodiment, a tooth mold is manufactured through a 3D printing machine based on seven orthodontic tooth data.

Here, the tooth molds are manufactured for a single patient, and since the tooth molds for a plurality of patients may be manufactured at the same time, there is a problem that the tooth molds of the patient may be mixed after 3D printing.

Therefore, identification information capable of identifying the tooth mold to be manufactured on the back of the orthodontic tooth data can be inserted in the intaglio form before 3D printing.

More specifically, as shown in FIG. 16A, the bottom of the gum is filled with a flat bottom shape with respect to the orthodontic tooth data, and the tooth mold identification information is engraved in the bottom surface as shown in FIG. 16B.

In this case, the tooth mold identification information may include information for identifying the tooth mold, such as a patient name and step information of the corrected tooth data.

When the identification information is inserted in the intaglio form as described above, the identification information is engraved in the intaglio form on the bottom of the tooth mold printed through the 3D printing machine.

When the tooth mold for the plurality of steps is completed, the transparent material is vacuum-compressed with the vacuum press on the mold to prepare a transparent straightener for the plurality of steps.

Here, since the transparent braces may be difficult to adapt to the teeth when the strength is high, a plurality of transparent braces having different strengths may be manufactured when the transparent braces are prepared at each step.

More specifically, TuPan, which is a transparent material, varies in strength depending on thickness, and the thinner the thickness, the weaker the strength, so that a plurality of transparent straighteners are sequentially produced from the thinnest thickness.

For example, if the transparent braces are manufactured by dividing the strength into three types, soft, medium, and hard, depending on the thickness, the transparent braces that the patient wears on the teeth at each step are worn in the order of Soft-> Medium-> Hard. Minimize discomfort, induce a quick adaptation to the teeth, shorten the wearing period of one transparent braces to improve hygiene and improve the effect of correction.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention.
