Description

A wire manufacturing system for orthodontic and dental maintenance considering elastic resilience, and a wire manufacturing method for orthodontic and dental maintenance using the same {SYSTEM OF MANUFACTURING ORTHODONTIC AND DENTITION MAINTENANCE WIRE AND METHOD FOR MANUFACTURING THE ORTHODONTIC AND DENTITION MAINTENANCE WIRE USING THE SAME}

The present invention relates to a manufacturing system of orthodontic wire and a method of manufacturing a orthodontic wire using the same, and in more detail, it is possible to manufacture relatively quickly, and it is possible to improve suitability according to various patient conditions, and Considering the difference in orthodontic treatment and dental maintenance treatment as well as the step-by-step characteristics of orthodontic treatment, a system for manufacturing personalized orthodontic wires that can be produced in sophisticated standards by considering the elastic resilience of the wire, and a method of manufacturing orthodontic wires using the same It is about.

Orthodontic treatment refers to the treatment of irregular teeth. In general, the correction of teeth is performed by attaching a bracket to the tooth and ligating an orthodontic archwire to align the position, inclination, or direction of the tooth by the restoring force of the arc line.

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

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

In the prior art such as EP2736444 described above, when a position and angle to be bent are input, a custom wire is manufactured by bending a ready-made rectangular wire using a separate bending device.

This prior art has the advantage of providing precise torque and in-out control according to the patient's tooth condition, but in reality, due to the inherent limitations of the bending process itself and the problems caused by the manufacturing method of the ready-made square wire, sufficient precision is achieved. There is a problem that it is difficult to secure.

In addition, when such an off-the-shelf wire is bent, a problem arises in that it is not possible to maintain the bent state at an exact angle at an intended position due to the elasticity of the material itself.

Particularly, in the case of a wire made of Nitinol, which is commonly used for orthodontic teeth, there is a problem in that the wire is not accurately bent as intended unless it is heated to a high temperature because of the property to return to its original state.

Further, the orthodontic teeth cannot be completed through a single orthodontic treatment, and a suitable wire must be used according to each orthodontic step, and the development of the orthodontic wire considering this until now is insufficient.

On the other hand, in the case of wires used for orthodontic teeth up to now, differences in characteristics between orthodontic treatment and dental maintenance treatment are not considered at all in the manufacture of wires, and related research is also necessary.

EP2736444 "ORTHODONTIC ARCHWIRES WITH REDUCED INTERFERENCE AND RELATED METHODS"

Accordingly, the technical problem of the present invention is conceived in this respect, and the object of the present invention is to process the orthodontic wire in consideration of the difference between the individual tooth structure of the orthodontic patient and the step-by-step characteristics of orthodontic treatment as well as the orthodontic treatment and the dental maintenance treatment.

In one embodiment, the tooth data acquisition unit acquires the patient's tooth data after the patient's teeth are corrected through the orthodontic treatment wire as current tooth data of the patient, and the target correction data selector, By comparing tooth data and target correction data for each correction step, target correction data close to the final orthodontic tooth data may be selected.

In one embodiment, the wire manufacturing unit may manufacture the wire for dental maintenance treatment when the comparison value of the current tooth data of the patient and the final orthodontic tooth data is less than or equal to the threshold value.

In an embodiment, when manufacturing the wire for dental maintenance treatment, a correction unit for generating a compensation algorithm in consideration of the elastic restoring force of the wire for dental maintenance treatment may be further included.

In an embodiment, the correction unit may generate the compensation algorithm by using predetermined elastic restoring force data according to the type of the wire for dental maintenance treatment or the measured elastic restoring force data.

In the method of manufacturing a wire for orthodontics according to an embodiment for realizing another object of the present invention, current tooth data of a patient is obtained. The final orthodontic tooth data is simulated and generated. The current tooth data of the patient and the final orthodontic tooth data are compared with a preset threshold. Based on the comparison result with the threshold value, an orthodontic treatment wire for performing orthodontic treatment for the patient's teeth and a wire for dental maintenance treatment for performing dentition maintenance for the patient's teeth are selectively manufactured.

In an embodiment, it may further include generating target correction data for each correction step of the patient based on the current tooth data of the patient and the final correction tooth data.

In one embodiment, when the comparison value of the patient's current tooth data and the final orthodontic tooth data is greater than the threshold value, the orthodontic treatment wire is manufactured, and the patient's current tooth data and the final orthodontic tooth data When the comparison value of is less than or equal to the threshold value, the wire for dental maintenance treatment may be manufactured.

In one embodiment, the step of manufacturing the orthodontic treatment wire includes selecting the target calibration data of the patient from the generated calibration step target calibration data, and the orthodontic treatment wire based on the target calibration data. It may include the step of manufacturing, and when the orthodontic treatment is finished, acquiring data of the patient's orthodontic teeth.

In one embodiment, the step of comparing the orthodontic tooth data of the patient obtained after the end of the orthodontic treatment as current tooth data of the patient, comparing it with the final orthodontic tooth data, and comparing again with a preset threshold value may be further included. have.

In an embodiment, in the step of selecting the target correction data of the patient, the current tooth data of the patient and the target correction data for each correction step may be compared to select target correction data close to the final correction tooth data.

In an embodiment, in the step of generating the compensation algorithm, the compensation algorithm may be generated by using elastic restoring force data preset according to the type of the wire for dental maintenance treatment.

According to embodiments of the present invention, it is determined whether or not to perform orthodontic treatment or orthodontic treatment based on the current tooth data of the patient, and manufacturing a matching wire to improve the suitability of the patient's orthodontic treatment and treatment effect. Can be further improved.

In particular, by creating target calibration data for each calibration step, determining which step the current tooth data of the patient who has finished calibration corresponds to, setting the target calibration data at that step, and creating a wire for calibration corresponding to this, In the case of treatment, the final target tooth cannot be corrected with a single treatment, and the characteristics that must be completed through a plurality of intermediate steps may be reflected, and accordingly, the effect of the orthodontic treatment may be improved.

However, in the actual orthodontic treatment, correction may proceed further than the target correction state. Therefore, when each correction step is completed, it is determined whether to perform additional orthodontic treatment or dental maintenance treatment through comparison with a preset threshold value. Thus, since the wire is produced, the effect of orthodontic treatment can be improved through effective production of the wire.

In particular, with regard to the characteristics of the wire used in the actual orthodontic treatment, considering that the elastic restoring force of the wire used in the dental maintenance treatment is higher than that of the wire used in the orthodontic treatment, an effective orthodontic wire is produced through different wires. Can be produced.

In other words, unlike orthodontic wires, the purpose of the wire for dental maintenance treatment is to ultimately maintain the dentition, and the wire is deformed when maintaining the dentition by forming the wire in consideration of the elastic resilience of the wire. 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 used according to the type of wire for dental maintenance treatment, so that a more accurate compensation algorithm can be generated.

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 orthodontic teeth according to an embodiment of the present invention. FIG. 2 is an image showing an example of patient tooth information acquired by the tooth data acquisition unit of FIG. 1. 3 is an image showing an example in which the wire manufactured by the wire manufacturing unit of FIG. 1 is fixed to the patient's teeth. 4 is a schematic diagram for explaining a target calibration data generation unit and a target calibration data selection unit of FIG. 1.

Referring to FIG. 1, a tooth orthodontic wire manufacturing system 10 (hereinafter referred to as a wire manufacturing system) according to this embodiment includes a tooth data acquisition unit 100, a simulation unit 200, a target correction 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 tooth data acquisition unit 100 acquires the current tooth data 110 of the patient, where the current tooth data 110 of the patient may be the current tooth data of the patient before receiving orthodontic treatment, and correction to be described later If correction is performed through treatment, it may be data of the patient's teeth after each correction step is completed.

That is, the tooth data acquisition unit 100 acquires the patient's tooth data before orthodontic treatment as the current tooth data 110 before performing orthodontic treatment for the patient, and in the process of performing orthodontic treatment for the patient, respectively The tooth data of the patient after the step of orthodontic treatment of is completed is acquired as current tooth data.

In this case, the tooth data acquisition unit 100 may acquire the current tooth data 110 of the patient by photographing the patient's tooth state or performing 3D scanning using a 3D scanner as shown in FIG. 2. .

Meanwhile, information on the skeleton and soft tissue of the patient may be obtained through the photographing process, and may be performed by Cone-Beam CT (CBCT) suitable for the field of dentistry. In the case of the CBCT, since the radiation dose is small and it is less affected by the intraoral metal prosthesis, it is suitable for application, but it is not limited thereto in obtaining the patient's tooth data.

In addition, tooth row 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 3D image through the 3D scanning, information on the size and shape of crowns and roots, and height or bone quality of the alveolar bone may be obtained.

Further, in the case of using the above 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, and a plaster model using CT or three-dimensional A method of scanning using a scanner can be applied.

Furthermore, the current tooth data 110 may include all data related to the patient's teeth, such as a patient's tooth X-ray picture, a patient's front and side picture, a correction instruction written by the attending physician, and a patient's tooth pattern. .

In particular, if the patient is in the growing stage, not only information about teeth protruding outside the gums but also information about teeth inside the gums is important, and thus data about this may naturally be included.

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

For example, based on the current tooth data 110 of the patient before the start of the orthodontic treatment, after performing pre-processing of removing an unnecessary area and automatically setting a preset resolution and size, the current tooth data 110 Based on the tooth baseline, the tooth that needs to be corrected is extracted according to the degree of departure, and the tooth is corrected so that it is aligned with the tooth baseline through the process of extending, rotating, and returning the tooth to simulate the final orthodontic tooth data 210 do. In this case, the orthodontic treatment of the teeth may be performed by using information on the orthodontic teeth of previously treated patients and information on the average teeth by age and gender of domestic patients.

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

Meanwhile, the simulation unit 200 may simulate the entire orthodontic treatment process in addition to simulating the final orthodontic tooth data 210, for example, simulating the entire treatment process according to malocclusion classification, or It is possible to simulate a process in each of the initial, intermediate, or late stages of orthodontic treatment, or to simulate a corresponding step when an unexpected result occurs in the treatment process.

Referring to FIG. 4, the target correction data generation unit 300 includes current tooth data 110 of a patient before orthodontic treatment obtained by the tooth data acquisition unit 100 and generated through the simulation unit 200. Based on the final orthodontic tooth data 210, target correction data 310, 320, ..., 330 of the patient's correction step are generated.

In general, in the case of orthodontic treatment, it is not possible to correct the first patient's tooth state to the final correction state through one orthodontic wire. In order to correct the first patient's tooth state to the final correction state, at least one intermediate Calibration steps have to be carried out. Accordingly, when each intermediate calibration step is performed, at least one suitable calibration wire must be produced.

On the other hand, the number of these intermediate correction steps may be variously determined according to the condition of the patient's teeth and the final correction condition, and if the first patient's tooth condition is relatively good, the correction can be performed through relatively few correction steps. If not, a relatively large number of calibration steps are required.

Accordingly, in the present embodiment, based on information such as the result of the orthodontic treatment that has been previously corrected by the target correction data generation unit 300, the patient's tooth condition and the final correction condition are considered to complete the orthodontic treatment. Create calibration steps, and generate target calibration data for each calibration step.

The target calibration data 310, 320, ..., 330 generated by the calibration step as described above are 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 by the patient, the calibration wire required at the calibration step can be manufactured.

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

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

More specifically, the target correction data selection unit 400, when the patient first starts orthodontic treatment, that is, the current tooth data of the patient acquired by the tooth data acquisition unit 100 before orthodontic treatment is performed. In the case of the first patient's tooth data 110, the first target correction data 310, which is the first target correction data, is selected from among the target correction data 310, 320, ..., 330.

In contrast, the target correction data selection unit 400 is an intermediate step in which the patient performs orthodontic treatment, that is, the current tooth data of the patient acquired by the tooth data acquisition unit 100 is corrected for the patient for which the correction has been performed. In the case of the tooth data 120, target correction data is selected by comparing the patient's orthodontic tooth data 120 and the target correction data 310, 320, ..., 330 with each other.

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

For example, referring to FIG. 4, it is determined that the patient's orthodontic tooth data 120 is most similar to the first target orthodontic data 310, and the patient's orthodontic tooth data 120 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 target calibration data.

In contrast, it is determined that the patient's orthodontic tooth data 120 is most similar to the second target orthodontic data 320, and the patient's orthodontic tooth data 120 is more than 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 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 of ), may be selected as target calibration data.

Meanwhile, the comparison operation unit 500 compares the current tooth data of the patient acquired by the tooth data acquisition unit 100 with the final orthodontic tooth data 210 generated by the simulation unit 200, and Compare with the value 510.

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

As described above, orthodontic treatment for the patient's teeth is generally performed through a plurality of steps, and whether orthodontic treatment should be additionally performed at each step of orthodontic treatment, and how to select target correction data if performed. As described. That is, when the target correction data selection unit 400 selects the first to nth target correction data 310, 320, ..., 330 of the intermediate stage of orthodontic treatment as the target correction data, 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 correction on the patient's teeth.

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

To this end, the preset threshold value 510 is between the n-th target calibration data 330 and the final calibration tooth data 210 which is the last step among the target calibration data, as shown in FIG. 4. It is preferably set to a value.

Thus, when comparing the current tooth data 110 and 120 of the patient and the final orthodontic tooth data 210 based on the preset threshold value 510, the comparison result is the n-th target correction data ( It is necessary to determine that it is not necessary to select 330) as target correction data in the next stage of orthodontic treatment.

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

As described above, in the comparison operation unit 500, whether or not a wire for orthodontic treatment for correcting the patient's teeth should be manufactured based on the preset threshold value 510, that is, the orthodontic treatment for the patient's teeth should be performed. A comparative judgment is made as to whether or not to make a wire for dentition maintenance treatment that performs dentition maintenance on the patient's teeth, that is, whether to perform dentition maintenance treatment on the patient's teeth.

When the comparison operation unit 500 has a comparison value of the patient's current tooth data 110 and 120 and the final orthodontic tooth data 210 greater than the preset threshold value 510 , To make a wire for orthodontic treatment to perform correction of the patient's teeth.

In contrast, in the comparison operation unit 500, the wire manufacturing unit 600 determines the comparison value of the patient's current tooth data 110 and 120 and the final orthodontic tooth data 210 as the preset threshold 510 In the following cases, a wire for dental maintenance treatment for performing dental maintenance on the patient's teeth 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, and as time passes even in the state of being corrected on the teeth. , Deformation may proceed by the elastic restoring force.

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

In contrast, in the case of a wire for dental indwelling treatment, it plays a role of maintaining a constant dentition for a patient's teeth for which orthodontic treatment has been completed, and the manufactured wire must not be deformed or be kept at a minimum. You can keep the dentition constant.

On the other hand, unlike the wire used for orthodontic treatment, the wire used for the dental maintenance treatment may be a wire having a large elastic resilience in consideration of the characteristics of such dental maintenance treatment.

Accordingly, in the present embodiment, the correction unit 700 further includes, and in the correction unit 700, when manufacturing the wire for dental maintenance treatment, a compensation algorithm in consideration of the elastic restoring force of the wire for dental maintenance treatment is used. Generate. That is, the correction unit 700 generates the compensation algorithm by using pre-set elastic restoring force data according to characteristics such as material, thickness, length, etc. of the type of wire for dental maintenance treatment. 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 experiment for the wire.

For example, when the wire is manufactured, deformation value information of the wire for manufacturing the dental wire for maintaining teeth is input based on the final orthodontic tooth data 210, but the deformation is performed in the same manner 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 by considering the elastic restoring force of the wire is obtained, and based on this, the wire fabrication unit 600 maintains the teeth. You can make a wire for treatment.

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

Meanwhile, since the compensation algorithm is generated based on preset elastic restoration data or measured elastic restoration force data, when a wire must be manufactured using a yield point, it may be generated as 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 a feedback amount of deformation of a wire through a separate measuring unit.

That is, the compensation algorithm in this embodiment is a compensation algorithm when manufacturing a wire that takes into account the elastic restoring force of the wire in manufacturing the wire for dental maintenance treatment, but in reality, the elastic restoring force is considered in the manufacture of the wire and must be additionally applied. It may be a concept including specific details of a mechanism for manufacturing a wire.

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

5 is a flowchart illustrating a method of manufacturing a wire for orthodontic use using the system for manufacturing a wire for orthodontic use of FIG. 1. Figure 6 is a flow chart showing in detail the method of manufacturing a wire for orthodontics of Figure 5;

5 and 6, in the method of manufacturing a wire for orthodontics, first, current tooth data of a patient is acquired (step S10).

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

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

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

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

Target correction data is generated based on the current tooth data 110 of the patient obtained as described above and the generated final correction tooth data 210 (step S30).

In the present embodiment, the target calibration data is target calibration data 310, 320, ... by the calibration step for performing orthodontic treatment from the current dental data 110 of the patient to the final dental data 210 for orthodontic treatment. , 330), the number of correction steps may be variously set according to a patient's condition or a final correction condition.

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

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

At this time, the current tooth data 110 of the patient to be compared may be tooth data before correction, if the patient has not started orthodontic treatment, and if the procedure is corrected through orthodontic treatment, each correction It may be the patient's orthodontic tooth data 120 after the step is finished.

However, the current tooth data of the patient used in the step of generating the target correction data (step S30) is to plan the overall step of tooth correction in advance, and only the tooth data before correction in a state in which the patient has not started orthodontic treatment. It can be said that this is the case.

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

In this case, since the preset threshold 510 is the same as described above, a duplicate description is omitted, and the difference between the current tooth data 110 of the patient and the final orthodontic tooth data 210 is a preset threshold. If it is greater than the value 510, a wire for orthodontic treatment is produced (step S50), and if the difference value is less than a preset threshold value 510, a wire for dental maintenance treatment is produced (step S60).

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

That is, in the step of manufacturing the orthodontic treatment wire (step S50), first, 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 selection step of the target correction data (step S51), when the patient first starts orthodontic treatment, that is, the current tooth data of the patient is the first patient's tooth data 110 before orthodontic treatment is performed. ), the first target calibration data 310, which is the first target calibration data, among the target calibration data 310, 320, ..., 330 may be selected.

In contrast, in the step of selecting the target correction data (step S51), if the patient is an intermediate step in performing orthodontic treatment, that is, the patient's corrected tooth data 120 at the step in which the current tooth data of the patient is corrected. If this is the case, target correction data may be selected by comparing the patient's orthodontic tooth data 120 and the target correction data 310, 320, ..., 330 with each other.

At this time, when the target correction data is selected, the final orthodontic tooth data is compared by comparing the current tooth data (110, 120) of the patient with the target correction data (310, 320, ..., 330) for each correction step. Target calibration data close to (210) can be selected.

For example, referring to FIG. 4 again, it is determined that the patient's orthodontic tooth data 120 is most similar to the first target orthodontic data 310, and the patient's orthodontic tooth data 120 is the first If it is determined that the target calibration data 310 is more calibrated, in the target calibration data selection step (step S51), the second target calibration data 320 may be selected as target calibration data.

In contrast, it is determined that the patient's orthodontic tooth data 120 is most similar to the second target orthodontic data 320, and the patient's orthodontic tooth data 120 is more than the second target orthodontic data 310 If it is determined that the calibration is less, in the selection step of the target calibration data (step S51), the second target calibration data 320 is selected as target calibration data, or the second target calibration data based on the similarity Third target calibration data (not shown), which is the next step in step 320, may be selected as 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).

Thereafter, orthodontic treatment is performed based on the produced orthodontic treatment wire (step S53), and when the orthodontic treatment of the corresponding step is completed, the orthodontic treatment wire is removed and the patient's orthodontic tooth data is obtained (step S53). S54).

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

On the other hand, the step of manufacturing the orthodontic treatment wire as described above (step S50) is repeatedly performed, and in the end, the current tooth data 120 and the patient's current tooth data 120 in the comparison step (step S40) with the preset threshold value. When the difference between the final orthodontic tooth data 210 becomes less than or equal to the threshold value 510, it is finally terminated.

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

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

In the case of manufacturing the wire for the dental maintenance treatment, that is, performing the dental maintenance treatment, it can be said that the orthodontic treatment has already been completed, so that one of the target calibration data for each step of the calibration can be selected as the target calibration data. There is no, in the end, the final orthodontic tooth data 210 is selected as the target correction data.

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

That is, in the case of manufacturing the wire for the treatment of dental maintenance, the final orthodontic tooth data 210 selected as the target correction data is substantially similar to or identical to the tooth data of the patient, that is, the tooth data of the patient who has finished orthodontic treatment. I can.

After that, a compensation algorithm in consideration of the elastic restoring force of the wire for dental maintenance treatment is generated (step S62).

In the case of a wire for dental maintenance treatment, it plays a role of maintaining a constant dentition with respect to the patient's teeth for which orthodontic treatment has been completed, and the fabricated wire must not be deformed or maintained at a minimum. You can keep it constant.

Therefore, when manufacturing a wire for dental maintenance 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 pre-set elastic restoring force data according to characteristics such as material, thickness, length, etc. of the type of wire for dental maintenance treatment. In this case, it has been described that the elastic resilience data can be quantified and stored using separate reference data or data obtained through a separate elastic resilience test for the wire.

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

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

Thereafter, by performing the dental maintenance treatment based on the manufactured wire for dental maintenance treatment (step S64), and performing such dental maintenance treatment, all orthodontic treatment for the patient is terminated.

According to the embodiments of the present invention as described above, it is determined whether or not to perform orthodontic treatment or dental maintenance treatment based on the current tooth data of the patient, and by manufacturing a matching wire, the suitability of the orthodontic treatment of the patient is improved. And can improve the treatment effect.

In particular, by creating target calibration data for each calibration step, determining which step the current tooth data of the patient who has finished calibration corresponds to, setting the target calibration data at that step, and creating a wire for calibration corresponding to this, In the case of treatment, the final target tooth cannot be corrected with a single treatment, and the characteristics that must be completed through a plurality of intermediate steps may be reflected, thereby improving the effect of orthodontic treatment.

However, in the actual orthodontic treatment, correction may proceed further than the target correction state. Therefore, when each correction step is completed, it is determined whether to perform additional orthodontic treatment or dental maintenance treatment through comparison with a preset threshold value. Thus, since the wire is produced, the effect of orthodontic treatment can be improved through effective production of the wire.

In particular, with regard to the characteristics of the wire used in the actual orthodontic treatment, considering that the elastic restoring force of the wire used in the dental maintenance treatment is higher than that of the wire used in the orthodontic treatment, an effective orthodontic wire is produced through different wires. Can be produced.

In other words, unlike orthodontic wires, the purpose of the wire for dental maintenance treatment is to ultimately maintain the dentition, and the wire is deformed when maintaining the dentition by forming the wire in consideration of the elastic resilience of the wire. 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 used according to the type of wire for dental maintenance treatment, so that a more accurate compensation algorithm can be generated.

You will understand that you can.
