A wire manufacturing system for orthodontic and orthodontic maintenance in consideration of elastic restoring force, and a manufacturing method for orthodontic and orthodontic wire manufacturing method using the same

The present invention relates to a system for manufacturing an orthodontic wire and a method for manufacturing an orthodontic wire using the same, and more particularly, can be manufactured relatively quickly, and can improve suitability according to various patient conditions, and In consideration of the step-by-step characteristics of orthodontic treatment and differences between orthodontic treatment and orthodontic treatment, a manufacturing system for a personalized orthodontic wire that can be produced in a sophisticated standard considering the elastic restoring force of the wire, and a method for manufacturing an orthodontic wire using the same is about

Orthodontic treatment refers to treatment that straightens irregular teeth. In general, orthodontics is made in a way that the position, inclination, or direction of the teeth are aligned by the restoring force of the arch wire by attaching a bracket to the teeth and ligating an orthodontic archwire.

Recently, a customized orthodontic technology has been introduced that uses computer software to design a bracket position or wire shape after making a patient's ideal tooth condition as a setup model.

3M INNOVATIVE PROPERTIES COMPANY's EP2736444 "ORTHODONTIC ARCHWIRES WITH REDUCED INTERFERENCE AND RELATED METHODS" acquires the shape of an arc line that matches the patient's tooth position, and announces the technology for producing a customized wire for lingual orthodontics consisting of multiple segments. have.

In the prior art, such as EP2736444, when a bending position and an angle are input, a custom wire is manufactured by bending a ready-made rectangular wire using a separate bending equipment.

Although this prior art has the advantage of providing precise torque and control of in-out according to the patient's tooth condition, in reality, a sufficient degree of precision is obtained due to problems caused by the manufacturing method of the ready-made prismatic wire and the intrinsic limitation of the bending process itself. There is a problem that it is difficult to obtain.

In addition, when bending such a ready-made wire, there is actually a problem in that the bent state cannot be maintained at the intended position at an accurate angle due to the elasticity of the material itself.

In particular, in the case of a wire made of nitinol, which is commonly used for orthodontic treatment, there is a problem in that it cannot be bent exactly as intended unless heated to a high temperature because of the property to return to its original state.

Furthermore, orthodontic treatment cannot be completed through one orthodontic treatment, and an appropriate wire must be used according to each orthodontic step.

On the other hand, in the case of the wire used for orthodontic treatment up to now, the difference in the characteristics of orthodontic treatment and orthodontic treatment is not considered at all in the manufacture of the wire, and related research is also required.

However, in actual orthodontic treatment, orthodontic treatment may proceed further than the targeted orthodontic state, so when each orthodontic step is completed, it is determined whether to perform additional orthodontic treatment or orthodontic treatment by comparing with a preset threshold value Since the wire is manufactured by doing so, the effect of orthodontic treatment can be improved through the effective production of the wire.

In particular, in relation to the characteristics of the wire used for actual orthodontic treatment, considering that the elastic restoring force of the wire used for orthodontic treatment is higher than that of the wire used for orthodontic treatment, effective orthodontic wire is produced through different wire production. can be produced

Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings.

1 is a block diagram showing a wire manufacturing system for orthodontics according to an embodiment of the present invention. FIG. 2 is an image illustrating an example of patient's tooth information obtained by the tooth data acquisition unit of FIG. 1 . 3 is an image illustrating an example in which the wire manufactured by the wire manufacturing unit of FIG. 1 is fixed to the patient's teeth. FIG. 4 is a schematic diagram for explaining the target calibration data generating unit and the target calibration data selecting unit of FIG. 1 .

1, the orthodontic wire manufacturing system 10 (hereinafter referred to as wire manufacturing system) according to the present embodiment includes a tooth data acquisition unit 100, a simulation unit 200, a target orthodontic data generation unit 300, and a target It includes a calibration data selection unit 400 , a comparison operation unit 500 , a wire manufacturing unit 600 , and a correction unit 700 .

The dental data acquisition unit 100 acquires the patient's current dental data 110, where the patient's current dental data 110 may be the patient's current dental data before receiving orthodontic treatment. If correction is made through treatment, it may be the patient's dental data after each correction step is completed.

That is, in the dental data acquisition unit 100, before orthodontic treatment is performed on the patient, the patient's dental data before orthodontic treatment is acquired as the current dental data 110, and in the process of performing orthodontic treatment on the patient, each The patient's tooth data after the orthodontic treatment stage is completed is acquired as the current tooth data.

In this case, the dental data acquisition unit 100 may acquire the patient's current dental data 110 by performing imaging or 3D scanning using a 3D scanner on the patient's dental condition as shown in FIG. 2 . .

Meanwhile, information on the patient's skeleton and soft tissue may be acquired through the imaging process, and may be performed by Cone-Beam CT (CBCT) suitable for the field of dentistry. The CBCT is suitable for application because the radiation dose is small and it is less affected by metal prostheses in the oral cavity, but is not limited thereto in obtaining the patient's dental data.

In addition, dentition and tooth information may be additionally obtained through the 3D scanning such as laser scanning. Here, an intraoral laser scanner may be applied for laser scanning. In the three-dimensional image through the 3D scanning, information on the size and shape of the crown and root, the height of the alveolar bone, or bone quality may be acquired.

Furthermore, when using the scanning method, for example, a method of scanning using a three-dimensional intraoral scanner, a method of scanning a PVC impression using a CT (computed tomography) scanner, a CT or three-dimensional plaster model A method of scanning using a scanner may be applied.

Furthermore, the current dental data 110 may include all data related to the patient's teeth, such as X-ray pictures of the patient's teeth, front and side pictures of the patient, orthodontic instructions written by the attending physician, and the patient's teeth. .

In particular, if the patient is in the growing phase, since information about the teeth protruding outside the gums as well as information about the teeth inside the gums is important, data on this may be included as well.

The simulation unit 200 simulates and generates the final orthodontic data 210 . In this case, the final orthodontic data 210 is ideal orthodontic data when the orthodontic treatment is finally completed based on the patient's current dental data 110 before the start of orthodontic treatment in the dental data acquisition unit 100. , may be simulated and generated in consideration of various factors such as the patient's age and gender, as well as the acquired dental data of the patient.

For example, based on the patient's current dental data 110 before the start of the orthodontic treatment, unnecessary areas are removed and pre-processing is performed to automatically set the current tooth data 110 to a preset resolution and size. Based on the tooth baseline, the tooth that needs correction is extracted according to the degree of deviation based on the tooth baseline, and the teeth are corrected to align with the tooth baseline through the tooth extension, rotation, and restoration process to simulate the final orthodontic data 210 . do. In this case, the orthodontic treatment may be performed by using information on orthodontic teeth of previously treated patients and information on average teeth by age and sex of domestic patients.

In this case, the final orthodontic data 210 generated through the simulation unit 200 is as illustrated in FIG. 3 . In FIG. 3 , a wire 701 for orthodontic treatment to be described later is also illustrated at the same time, and the final orthodontic data 210 is ultimately maintained in an orthodontic state through the wire 701 for orthodontic treatment.

On the other hand, the simulation unit 200, in addition to simulating the final orthodontic data 210, may simulate the entire orthodontic treatment process, for example, simulate the entire treatment process according to the malocclusion classification, It is also possible to simulate the process at the initial, middle, or end of orthodontic treatment, or to simulate a corresponding step when an unexpected result occurs in the treatment process.

Referring to FIG. 4 , the target orthodontic data generating unit 300 includes the patient's current dental data 110 before orthodontic treatment acquired by the dental data acquiring unit 100 and the simulation unit 200 generated through the Based on the final orthodontic data 210, target correction data 310, 320, ..., 330 of the patient's orthodontic steps are generated.

In general, in the case of orthodontic treatment, it is not possible to correct the initial patient's dental state to the final orthodontic state through one orthodontic wire. A corrective step should be performed. Accordingly, in each case of performing each intermediate calibration step, at least one suitable calibration wire must also be manufactured.

On the other hand, the number of these intermediate orthodontic steps may be variously determined according to the state of the patient's teeth and the final orthodontic state, and if the initial patient's dental condition is relatively good, the correction can be performed through relatively few orthodontic steps. , otherwise a relatively large number of calibration steps are required.

Accordingly, in this embodiment, based on information such as the result of orthodontic treatment that has been previously corrected in the target orthodontic data generating unit 300, in consideration of the state of the patient's teeth and the final orthodontic state, to complete orthodontic treatment Calibration steps are generated, and target calibration data are generated at each calibration step.

The generated target correction data (310, 320, ..., 330) for each stage of correction is stored as reference data for manufacturing an orthodontic wire through the orthodontic wire manufacturing system according to the present embodiment, Based on the target calibration data corresponding to the calibration step required for the patient, the calibration wire required in the calibration step may be manufactured.

The target calibration data selection unit 400 selects the target calibration data of the patient from the plurality of target calibration data 310 , 320 , ..., 330 generated by the target calibration data generation unit 300 . .

When it is determined that the orthodontic treatment wire is manufactured by the comparison operation unit 500 to be described later, the target calibration data selection unit 400 determines that orthodontic treatment is necessary, the target calibration data 310, 320, ..., 330) to select the patient's target correction data.

More specifically, the target orthodontic data selection unit 400, when the patient first starts orthodontic treatment, that is, before orthodontic treatment is performed, the patient's current dental data obtained by the dental data obtaining unit 100 is In the case of the first patient's dental data 110 , the first target orthodontic data 310 that is the first target orthodontic data among the target orthodontic data 310 , 320 , ..., 330 is selected.

On the other hand, if the target orthodontic data selection unit 400 is an intermediate stage in which the patient performs orthodontic treatment, that is, the patient's current dental data obtained by the dental data acquisition unit 100 is the orthodontic treatment of the patient. In the case of the dental data 120 , the target orthodontic data is selected by comparing the patient's orthodontic data 120 with the target orthodontic data 310 , 320 , ..., 330 .

In this case, the target orthodontic data most similar to the patient's orthodontic data 120 is selected, and if the patient's orthodontic data corresponds to a stage in which correction is more than the selected target orthodontic data, the selected target orthodontic data It is possible to select the target calibration data of the next step as the final target calibration data. On the other hand, if the orthodontic tooth data of the patient corresponds to a stage in which correction is less than the selected target correction data, the selected target correction data is selected as the final target correction data, or the next stage of the selected target correction data is selected. The target calibration data may be selected as the final target calibration data.

For example, referring to FIG. 4 , it is determined that the orthodontic data 120 of the patient is most similar to the first target orthodontic data 310 , and the orthodontic data 120 of the patient is the first target. When it is determined that the calibration data 310 has been further calibrated, the target calibration data selection unit 400 may select the second target calibration data 320 as the target calibration data.

On the other hand, it is determined that the patient's orthodontic data 120 is most similar to the second target orthodontic data 320 , and the patient's orthodontic data 120 is more similar to the second target orthodontic data 310 . If it is determined that the calibration is less, the target calibration data selection unit 400 selects the second target calibration data 320 as the target calibration data, or the second target calibration data 320 based on the similarity. ), the third target calibration data (not shown), which is the next step, may be selected as the target calibration data.

On the other hand, the comparison operation unit 500 compares the patient's current tooth data obtained by the tooth data obtaining unit 100 with the final orthodontic data 210 generated by the simulation unit 200, and a preset threshold Compare with value 510 .

In this case, the preset threshold value 510 is the determination of whether to produce a wire for orthodontic treatment that performs orthodontic treatment on the patient's teeth, or a wire for orthodontic treatment that performs dental maintenance on the patient's teeth. As a reference value, it may be a preset value.

As described above, orthodontic treatment for a patient's teeth is generally performed through a plurality of steps, and whether orthodontic treatment should be additionally performed at each orthodontic treatment step, if performed, how to select target orthodontic data As described. That is, when the first to n-th target calibration data 310, 320, ..., 330 of the intermediate stage of orthodontic treatment are selected as target calibration data by the target calibration data selection unit 400, the comparison The result of the comparison operation in the operation unit 500 should also be derived as producing a wire for orthodontic treatment that performs orthodontic treatment on the patient's teeth in the same way.

Accordingly, the preset threshold value 510 is the target calibration data in the target calibration data selection unit 400, and the first to nth target calibration data 310, 320, ..., 330) is not selected, and the final orthodontic data 210 must be set to be selected.

To this end, as shown in FIG. 4 , the preset threshold value 510 is between the nth target correction data 330 , which is the last stage among the target correction data, and the final orthodontic tooth data 210 , as shown in FIG. 4 . It is preferably set to a value.

Thus, when comparing the patient's current dental data 110 and 120 with the final orthodontic data 210 based on the preset threshold 510, the comparison result is the n-th target orthodontic data ( 330) is necessary to determine that it does not need to be selected as the target correction data in the stage of the next stage of orthodontic treatment.

For example, if the value of comparing the patient's current dental data with the final orthodontic data, for example, the difference between the two data is greater than the preset threshold value, it may be determined that orthodontic treatment is additionally required. In addition, if the difference value between the two data is smaller than the preset threshold value, it may be determined that dental maintenance treatment is necessary.

As described above, whether or not the orthodontic treatment wire for performing orthodontic treatment on the patient's teeth should be manufactured based on the preset threshold value 510 in the comparison operation unit 500, that is, the orthodontic treatment should be performed on the patient's teeth. Whether or not, or whether to manufacture a wire for dental maintenance treatment for performing dental maintenance for the patient's teeth, that is, to perform a comparative judgment on whether to perform the dental maintenance treatment for the patient's teeth.

When the wire manufacturing unit 600 compares the patient's current tooth data 110 , 120 and the final orthodontic tooth data 210 in the comparison operation unit 500 , the comparison value is greater than the preset threshold value 510 . , manufactures a wire for orthodontic treatment to perform orthodontic treatment on the patient's teeth.

On the other hand, in the wire manufacturing unit 600 , the comparison value between the patient's current tooth data 110 , 120 and the final orthodontic tooth data 210 in the comparison operation unit 500 is the preset threshold value 510 . In the following cases, a wire for maintaining orthodontic treatment for maintaining the teeth of the patient is manufactured.

On the other hand, since the wire contains metal and has elastic restoring force, even if the wire is deformed by the calculated value, the actual wire may be deformed less than the calculated value, , may be deformed by the elastic restoring force.

However, in the case of the wire for orthodontic treatment, as described above, since a plurality of orthodontic treatment steps are required, even if the wire manufactured in the corresponding orthodontic treatment step is deformed, the wire can be re-manufactured in consideration of this in the next step. Exact consideration may be omitted.

On the other hand, in the case of a wire for treatment of indwelling teeth, the orthodontic treatment is performed on the patient's teeth for which the orthodontic treatment has been completed, to perform a role of maintaining the dentition of the corresponding tooth. can keep the dentition constant.

On the other hand, unlike the wire used for orthodontic treatment, the wire used for orthodontic treatment may be a wire having a large elastic restoring force in consideration of the characteristics of the orthodontic treatment.

Therefore, in this embodiment, the correction unit 700 is further included, and in the correction unit 700, when manufacturing the wire for tooth maintenance treatment, a compensation algorithm considering the elastic restoring force of the wire for tooth maintenance treatment is performed. create That is, the compensator 700 generates the compensation algorithm by using preset elastic restoring force data according to the type of the orthodontic treatment wire, ie, material, thickness, length, and the like. In this case, the elastic restoring force data may be quantified and stored using separate reference data or data obtained through a separate elastic restoring force test for the corresponding wire.

For example, when manufacturing the wire, deformation value information of the wire for manufacturing the wire for maintaining teeth is input based on the final orthodontic tooth data 210, but the deformation is performed in the same way as the input deformation value information. In this case, the actual deformation amount due to the elastic restoring force of the wire may be smaller than the target deformation amount. Thus, by applying the compensation algorithm generated by the correction unit 700, the actual deformation amount information for realizing the target deformation amount in consideration of the elastic restoring force of the wire is obtained, and based on this, the wire manufacturing unit 600 maintains the teeth A therapeutic wire can be crafted.

In this case, the compensation algorithm, as described above, is generated by accurately measuring the elastic restoring force for each characteristic of the wire for dental maintenance treatment in addition to being generated using preset elastic restoring force data according to the characteristics of the tooth maintenance treatment wire. can be

On the other hand, when the compensation algorithm is generated based on preset elastic recovery data or measured elastic recovery force data, when a wire is to be manufactured using a yield point, it may be generated with a concept including a manufacturing mechanism for such a wire. .

Furthermore, the compensation algorithm may be generated as a concept including such a manufacturing mechanism when manufacturing a wire by receiving feedback on the amount of deformation of the wire through a separate measurement unit.

That is, the compensation algorithm in this embodiment is a compensation algorithm when manufacturing a wire in consideration of the elastic restoring force of the wire in manufacturing the wire for dental maintenance treatment, but it should be additionally applied in consideration of the elastic restoring force in actually manufacturing the wire. It may be a concept including specific details of the manufacturing mechanism of the wire.

Hereinafter, with reference to FIGS. 5 and 6, a method for manufacturing orthodontic wire using the orthodontic wire manufacturing system described with reference to FIGS. 1 to 4 will be described.

5 is a flowchart illustrating a method of manufacturing orthodontic wire using the orthodontic wire manufacturing system of FIG. 1 . 6 is a flowchart illustrating in detail the method of manufacturing the orthodontic wire of FIG. 5 .

5 and 6, in the orthodontic wire manufacturing method, first, the patient's current tooth data is acquired (step S10).

In this case, the acquired data is the patient's current dental data 110 , and may be the patient's current dental data before receiving orthodontic treatment.

However, in the step of comparing with the threshold value to be described later, in the case of correction through orthodontic treatment, the patient's orthodontic tooth data 120 after each orthodontic step is completed is converted to the patient's current tooth data 110 . considered and a comparison with a threshold may be performed.

Thereafter, the final orthodontic data 210 is simulated and generated (step S20).

The method of obtaining the current dental data and the method of generating the final orthodontic data are the same as described above.

Target orthodontic data is generated based on the patient's current dental data 110 and the final orthodontic data 210 obtained as described above (step S30).

In this embodiment, the target orthodontic data is the target orthodontic data 310, 320, ... , 330), the number of the calibration steps may be variously set according to the patient's condition or the final calibration status.

In addition, the target calibration data (310, 320, ..., 330) for each calibration step formed through this is for producing a wire for orthodontic treatment that matches each target calibration data in the manufacturing step of a wire for orthodontic treatment to be described later. stored as reference data.

Thereafter, the patient's current dental data 110 and the final orthodontic data 210 are compared and compared with a preset threshold value 510 (step S40).

At this time, the patient's current dental data 110, which is the target of comparison, may be the dental data before orthodontic treatment if the patient has not started orthodontic treatment. It may be the orthodontic data 120 of the patient after the step is completed.

However, the patient's current dental data used in the step of generating the target orthodontic data (step S30) is to plan the overall stage of orthodontic treatment in advance, and only the dental data before orthodontic treatment in which the patient has not started orthodontic treatment It can be said that this applies.

Thus, the patient's current dental data 110 and the final orthodontic data 210 are compared, and the difference is compared with a preset threshold value 510 .

In this case, since the preset threshold value 510 is the same as described above, a redundant description is omitted, and the difference value between the patient's current dental data 110 and the final orthodontic data 210 is a preset threshold. If it is greater than the value 510, a wire for orthodontic treatment is manufactured (step S50), and if the difference value is less than or equal to a preset threshold value 510, a wire for orthodontic treatment is manufactured (step S60).

Hereinafter, the manufacturing of the wire for orthodontic treatment (step S50) will be described as follows.

That is, in the step of manufacturing the wire for orthodontic treatment (step S50), first, the target calibration data of the patient is selected from the generated target calibration data 310, 320, ..., 330 for each calibration step ( step S51).

More specifically, in the step of selecting the target orthodontic data (step S51), when the patient starts orthodontic treatment for the first time, that is, the patient's current dental data is the first patient's dental data 110 before orthodontic treatment is performed. ), the first target calibration data 310 that is the first target calibration data among the target calibration data 310 , 320 , ..., 330 may be selected.

On the other hand, in the step of selecting the target orthodontic data (step S51), if the patient is an intermediate step in performing orthodontic treatment, that is, the patient's orthodontic data 120 at the stage in which the patient's current dental data is orthodontic. In the case of , the target orthodontic data may be selected by comparing the patient's orthodontic data 120 with the target orthodontic data 310 , 320 , ..., 330 .

At this time, when the target orthodontic data is selected, the patient's current tooth data 110 , 120 is compared with the target orthodontic data 310 , 320 , ..., 330 for each orthodontic stage to compare the final orthodontic data Target calibration data close to 210 may be selected.

For example, referring back to FIG. 4 , it is determined that the orthodontic data 120 of the patient is most similar to the first target orthodontic data 310 , and the orthodontic data 120 of the patient is the first orthodontic data 120 . When it is determined that the target calibration data 310 has been further calibrated, in the selection step of the target calibration data (step S51 ), the second target calibration data 320 may be selected as the target calibration data.

On the other hand, it is determined that the patient's orthodontic data 120 is most similar to the second target orthodontic data 320 , and the patient's orthodontic data 120 is more similar to the second target orthodontic data 310 . If it is determined that the calibration is less, in the step of selecting the target calibration data (step S51), the second target calibration data 320 is selected as the target calibration data, or the second target calibration data based on the similarity The third target calibration data (not shown), which is the next step in step 320 , may be selected as the target calibration data.

As described above, when the target calibration data is selected, the wire for orthodontic treatment is manufactured based on the target calibration data (step S52).

After that, orthodontic treatment is performed based on the manufactured wire for orthodontic treatment (step S53), and when the orthodontic treatment of the corresponding step is completed, the orthodontic treatment wire is removed and orthodontic data of the patient is obtained (step S53) S54).

Here, the method of obtaining the patient's orthodontic data is substantially the same as the method of obtaining the patient's current dental data in the previous initial step (step S10), and the patient's orthodontic data 120 obtained in this way is the patient's orthodontic data. It is regarded as the current tooth data and compared with the final orthodontic data 210 in the step of comparing with the preset threshold value (step S40).

On the other hand, manufacturing the wire for orthodontic treatment as described above (step S50) is repeatedly performed, and eventually, the patient's current tooth data 120 and the When the difference between the final orthodontic data 210 is less than or equal to the threshold value 510, the end result.

Thus, when the manufacturing of the wire for orthodontic treatment (step S50) is finished, the manufacturing of the orthodontic treatment wire (step S60) is performed, and the specific step of manufacturing the orthodontic treatment wire (step S60) is performed. S60) is as follows.

That is, in the step of manufacturing the orthodontic wire for the orthodontic treatment (step S60), first, the final orthodontic tooth data is selected as the patient's target orthodontic data (step S61).

In the case of manufacturing the wire for the orthodontic treatment, that is, in the case of performing the orthodontic treatment, it can be said that the orthodontic treatment has already been completed, so that one of the target orthodontic data for each stage of orthodontics can be selected as the target orthodontic data. In the end, the final orthodontic tooth data 210 is selected as the target orthodontic data.

In this case, in order to perform dental maintenance treatment, since the difference between the patient's dental data and the final dental data is less than or equal to a threshold value, it may vary depending on the setting of the threshold, but substantially the patient's dental data is the final dental data. It can be said that it is almost similar or identical to the difference data.

That is, when manufacturing the wire for maintaining orthodontic treatment, the final orthodontic data 210 selected as target orthodontic data is substantially similar to or identical to the patient's dental data, that is, the patient's dental data for which orthodontic treatment has been completed. can

Thereafter, a compensation algorithm is generated in consideration of the elastic restoring force of the orthodontic treatment wire (step S62).

In the case of a wire for maintaining orthodontic treatment, the orthodontic treatment is performed to maintain the dentition of the corresponding tooth uniformly with respect to the patient's teeth. can be kept constant.

Therefore, when manufacturing a wire for orthodontic treatment, it is necessary to generate a compensation algorithm in consideration of the elastic restoring force of the wire. That is, the compensation algorithm is generated by using preset elastic restoring force data according to the type of the wire for the orthodontic treatment, ie, material, thickness, length, and the like. In this case, as described above, the elastic restoring force data can be quantified and stored by using separate reference data or data obtained through a separate elastic restoring force test for the wire.

Thereafter, a wire for maintaining orthodontic treatment is manufactured based on the generated compensation algorithm and the final orthodontic data selected as the target orthodontic data of the patient (step S63).

In this case, the deformation amount of the manufactured wire is to add the deformation amount compensated through the compensation algorithm to the deformation amount on the final orthodontic tooth data, and may be variously set according to the elastic restoring force of the wire.

Thereafter, dental maintenance treatment is performed based on the manufactured wire for maintaining orthodontic treatment (step S64), and by performing this orthodontic treatment, all orthodontic treatment for the patient is ended.

According to the embodiments of the present invention as described above, the suitability of the patient's orthodontic treatment is improved by determining whether orthodontic treatment should be performed or orthodontic treatment should be performed based on the patient's current dental data and manufacturing a wire matching the same. and can further improve the therapeutic effect.

In particular, by generating target orthodontic data for each orthodontic stage, determining which stage the patient's current tooth data for which correction has been completed corresponds to, setting target orthodontic data in the corresponding stage, and generating orthodontic wires corresponding thereto, In the case of treatment, it is not possible to correct the final target tooth with one treatment, and it is possible to reflect the characteristics that treatment must be completed through a plurality of intermediate steps, thereby improving the effectiveness of orthodontic treatment.

However, in actual orthodontic treatment, orthodontic treatment may proceed further than the targeted orthodontic state, so when each orthodontic step is completed, it is determined whether to perform additional orthodontic treatment or orthodontic treatment by comparing with a preset threshold value Thus, the effect of orthodontic treatment can be improved through the effective production of the wire.

In particular, in relation to the characteristics of the wire used for actual orthodontic treatment, considering that the elastic restoring force of the wire used for orthodontic treatment is higher than that of the wire used for orthodontic treatment, effective orthodontic wire is produced through different wire production. can be produced

That is, unlike orthodontic wire, in the case of orthodontic treatment wire, the purpose is ultimately to maintain teeth. It is possible to improve the effect of dental maintenance treatment by preventing deterioration in advance.

In this case, in consideration of the elastic restoring force, various data can be utilized according to the type of wire for orthodontic treatment, so that it is possible to generate a more accurate compensation algorithm.
