Embodiments of the present invention will be described in detail with reference to the drawings. In the following description, the same elements are designated by the same reference numerals, and duplicate description will be omitted. Each embodiment and embodiment can be applied in combination as appropriate.

As shown in FIG. 1, the orthodontic treatment support system 1 is communicably connected to a person in charge terminal device 10 provided for each person in charge of orthodontic treatment and a plurality of person in charge terminal devices 10 via a network NW. The orthodontic treatment support device 20 is provided. Here, the person in charge is a dentist, a dental technician, etc. who creates a mouthpiece (aligner) for orthodontic treatment. In the present embodiment, an orthodontic treatment in which a plurality of mouthpieces are provided to a patient to correct teeth is exemplified, but the present invention can also be applied to other orthodontic treatments such as wire orthodontics.

<Person in charge terminal device>
The person in charge terminal device 10 includes an operation unit 11, a display unit 12, and a control unit 13. The operation unit 11 is composed of a keyboard, a mouse, a touch panel, and the like, and outputs an operation result by the user to the control unit 13. The display unit 12 is composed of a monitor or the like, and displays an image (orthodontic treatment information such as similarity described later) based on the control by the control unit 13. The control unit 13 is composed of, for example, a CPU (Central Processing Unit), a ROM (Read-Only Memory), a RAM (Random Access Memory), an input / output circuit, and the like. The control unit 13 operates by a dedicated program as content on general-purpose software (browser), and transmits the operation result (orthodontic treatment information) by the operation unit 11 to the orthodontic treatment support device 20 or orthodontic treatment. The degree of similarity, the degree of achievement, etc. calculated by the treatment support device 20 are received and displayed on the display unit 12.

<Orthodontic treatment support device>
The orthodontic treatment support device 20 is a server composed of, for example, a CPU (Central Processing Unit), a ROM (Read-Only Memory), a RAM (Random Access Memory), an input / output circuit, and the like. The orthodontic treatment support device 20 collects the orthodontic treatment information 31 transmitted by the person in charge terminal device 10, calculates the similarity and the like, and transmits the calculation result and the like to the corresponding person in charge terminal device 10.

The orthodontic treatment support device 20 includes an information collecting unit 21, a storage unit 22, and a similarity calculation unit 23 as functional units. The information collecting unit 21 collects the orthodontic treatment information 31 transmitted by the person in charge terminal device 10, and stores the collected orthodontic treatment information 31 in the storage unit 22. The similarity calculation unit 23 calculates the similarity of the tooth pattern information included in the orthodontic treatment information 31, stores the calculation result in the storage unit 22 as a kind of the orthodontic treatment information 31, and corresponds to the calculation result and the like. The person in charge of the transmission is transmitted to the terminal device 10.

The storage unit 22 stores the orthodontic treatment information 31 of the existing patient (treated patient). The orthodontic treatment information 31 contains the patient's personal ID (name, number, etc.), gender, date of birth, height and weight, and the ID (name) of the person in charge (dentist, dental technician, etc.) as information for each existing patient. , Number, etc.), including. Further, the orthodontic treatment information 31 includes treatment cost, treatment period, presence / absence and location of tooth extraction, treatment plan (orthodontic treatment plan), etc. as information for each existing patient. In the orthodontic treatment plan, for example, in orthodontics using a mouthpiece as in the present embodiment, what kind of tooth type (ideal tooth type information described later) is the ultimate purpose of treatment, and what shape is used for how long. The plan is to use the mouthpieces (aligners, orthodontic appliances) of the above, which will be the basis of orthodontics. The treatment cost, treatment period, presence / absence of tooth extraction, and location are also information included in the orthodontic treatment plan.

Further, the orthodontic treatment information 31 includes tooth type information (pretreatment tooth type information) at the start of orthodontic treatment and ideal at the start of orthodontic treatment as tooth type information (three-dimensional tooth type model information) for each existing patient. Includes tooth pattern information (ideal tooth pattern information) and tooth pattern information at the end of orthodontic treatment (post-treatment tooth pattern information).

The pretreatment tooth type information is information representing a three-dimensional tooth type (dentition) obtained by three-dimensionally scanning the tooth type at the start of treatment of a patient. The ideal tooth type information is information representing a three-dimensional tooth type (dentition) determined by the person in charge as a target of orthodontic treatment at the start of treatment of the patient. The post-treatment tooth pattern information is information representing a three-dimensional tooth pattern (dentition) obtained by three-dimensionally scanning the tooth pattern at the end of treatment of the patient. The pretreatment tooth type information and the ideal tooth type information are also the information included in the orthodontic treatment plan.

In addition, the orthodontic treatment information 31 includes the degree of achievement for each new patient or existing patient. At the end of treatment for each patient, the degree of achievement is calculated by the similarity calculation unit 23 based on the degree of similarity between the ideal tooth type information and the post-treatment tooth type information. In other words, if the degree of similarity is high, it means that the degree of achievement is high as an orthodontic treatment.

Further, the orthodontic treatment information 31 includes a degree of similarity (information regarding the degree of similarity) obtained when the orthodontic treatment support system 1 is used. IDs of existing patients with high similarity obtained in the similarity calculation process described later (IDs of one or more existing patients adopted when providing orthodontic treatment, or IDs of one or more existing patients who were not adopted but have high similarity. The ID of an existing patient, etc.) may be included.

The similarity calculation unit 23 calculates the similarity between the pretreatment tooth patterns of all existing patients stored in the storage unit 22 and the pretreatment tooth patterns of new patients transmitted from the person in charge terminal 10. The similarity calculation unit 23 stores the calculated similarity as a kind of orthodontic treatment information 31 of the new patient in the storage unit 22 in association with the ID of the new patient. Further, the similarity calculation unit 23 causes the display unit 12 of the person in charge terminal device 10 to display the calculation result as the “similarity”. The similarity can be calculated, for example, as a percentage. As the similarity calculation method, the similarity calculation unit 23 can use, for example, similar drawing search AI software (3D similar shape search system utilizing artificial intelligence) or the like. Further, the similarity calculation unit 23 provides the calculated similarity and the orthodontic treatment information 31 (orthodontic treatment plan, ideal tooth type information, etc.) of the existing patient corresponding to the similarity (from the storage unit 21). It can be read out and displayed on the display unit 12 of the person in charge terminal device 10).

The similarity calculation unit 23 may calculate the similarity by extracting only the orthodontic treatment information 31 treated by the designated person from the information of the existing patient, for example. Further, the similarity calculation unit 23 may calculate the similarity by extracting only the orthodontic treatment information 31 with tooth extraction from the information of the existing patient, for example. By calculating the similarity by narrowing down the conditions in this way, it is possible to present information on existing patients that can be used as a more accurate reference to new patients.

Further, the similarity calculation unit 23 reads out the ideal tooth type information and the post-treatment tooth type information of the existing patient, and calculates the similarity based on the read out ideal tooth type information and the post-treatment tooth type information. That is, the "achievement degree" for the orthodontic treatment that has been treated is calculated based on the orthodontic treatment information 31 of the existing patient. The similarity calculation unit 23 stores the calculated similarity (achievement level) in the storage unit 22 as a kind of orthodontic treatment information 31 of the existing patient in association with the ID of the existing patient. Further, the similarity calculation unit 23 causes the display unit 12 of the person in charge terminal device 10 to display the calculation result. The degree of similarity (achievement) can be calculated as a percentage, for example. In other words, the "achievement level" can quantitatively grasp the degree of achievement of the treatment of the existing patient who has already been completed as the orthodontic treatment.

Further, since the orthodontic treatment support device 20 associates the achievement level with the person in charge in the orthodontic treatment information 31, it is also possible to calculate the average value of the achievement level for each person in charge. As a result, the skill of each person in charge can be quantified and visualized, which can be referred to when selecting a dental treatment plan or the like or when selecting a person in charge.

Further, the similarity calculation unit 23 calculates the similarity from the ideal tooth type information of the new patient and the post-treatment tooth type information after the orthodontic treatment of the new patient is completed. That is, the "achievement level" of the orthodontic treatment of the new patient is calculated. The similarity calculation unit 23 stores the calculated similarity (achievement level) in the storage unit 22 as a kind of orthodontic treatment information 31 of the new patient in association with the ID of the new patient. Further, the similarity calculation unit 23 causes the display unit 12 of the person in charge terminal device to display the calculation result. The degree of similarity (achievement) can be calculated as a percentage, for example. In other words, the "achievement level" can quantitatively grasp how much the treatment of the completed new patient has achieved as an orthodontic treatment.

In addition, when calculating the similarity, the similarity calculation unit 23 determines the similarity based on at least one of the gender, age, height, weight, and presence / absence of tooth extraction between the patients, in addition to the similarity between the tooth types. To correct. By calculating the degree of similarity by taking into account factors such as gender as well as dental type information, it is possible to more accurately provide orthodontic treatment plans, etc. based on the information of existing patients who are closer to the new patient (by display). Can be presented). For example, if only the tooth type information is evaluated, multiple patients with the same degree of similarity may be presented. In such a case, differentiation can be achieved based on the corrected similarity, and a more accurate orthodontic treatment plan or the like can be provided.

Further, the similarity calculation unit 23 reads out the similarity stored in the storage unit 22 for each person in charge, and calculates the comprehensive evaluation of the degree of similarity of the plurality of existing patients in charge of the person in charge. The similarity calculation unit 23 stores the calculated comprehensive evaluation as a kind of orthodontic treatment information 31 of the existing patient in the storage unit 22 in association with the patient's ID and / or the person in charge's ID. The similarity calculation unit 23 can calculate the average value (arithmetic mean) of the similarity of a plurality of existing patients as a calculation method of the comprehensive evaluation. The comprehensive evaluation of the similarity can be used as an evaluation of the treatment technique of the person in charge of the existing patient.

The person in charge selected the orthodontic treatment information 31 of one existing patient from the orthodontic treatment information 31 of a plurality of existing patients having a high degree of similarity in consideration of the comprehensive evaluation of the person in charge of the existing patient. Based on the ideal tooth type information and the treatment method included in the orthodontic treatment information 31, the ideal tooth type information and the treatment method of the new patient can be determined. For example, the person in charge can refer to the orthodontic treatment information 31 of a better treatment method by selecting the orthodontic treatment information 31 of the existing patient having a high comprehensive evaluation of the person in charge.

Further, the similarity calculation unit 23 transmits the orthodontic treatment information 31 of the existing patient having the highest similarity to the person in charge terminal device 10 for each of the plurality of persons in charge. The control unit 13 of the person in charge terminal device 10 receives the transmitted orthodontic treatment information 31 of the existing patient, and causes the display unit 12 to display the received orthodontic treatment information 31 of the existing patient.

The person in charge decides whether to take charge of the new patient by himself or to ask another person based on the similarity between the ideal tooth type information of the existing patient and the post-treatment tooth type information included in the orthodontic treatment information 31. can do. For example, the person in charge is a new patient to the person who has the highest degree of similarity between the ideal tooth type information and the post-treatment tooth type information of the existing patient included in the orthodontic treatment information 31 among a plurality of persons including himself / herself. Can be decided to be in charge of.

[Example 1]
Next, Example 1 of the present invention will be described. As shown in FIG. 2, in the orthodontic treatment support method according to the first embodiment, the existing patient's tooth pattern collecting step S1, the new patient's tooth pattern collecting step S2, the similarity calculation step S3, and the treatment plan providing step. S4 and. In Example 1, it is assumed that the orthodontic treatment information 31 does not include the "achievement level" of the existing patient.

The tooth pattern collecting step S1 of the existing patient is a step of collecting information on the pretreatment tooth pattern of the existing patient. In orthodontic treatment where multiple mouthpieces are provided to the patient to correct the teeth, the patient's mouth is usually photographed using a 3D optical scanner before the treatment, and the shape of the teeth and the condition of the dentition are used as data. Since it has been acquired, the information can be used as pretreatment tooth type information. The orthodontic treatment information 31 of the existing patient including the person ID and the pretreatment tooth type information is stored in the storage unit 22 of the orthodontic treatment support device 20. In the tooth pattern collecting step S1 of the existing patient, the orthodontic treatment information 31 including the orthodontic treatment plan of the existing patient is also collected and stored in the storage unit 22. That is, it can be said that the tooth pattern collecting step S1 is an orthodontic treatment information collecting step for collecting the orthodontic treatment information 31 including the pretreatment tooth pattern information and the orthodontic treatment plan of the existing patient. Such an orthodontic treatment information collecting step is appropriately executed at the time of treatment of an existing patient.

The tooth pattern collecting step S2 of the new patient is a step of collecting information on the pretreatment tooth pattern of the new patient. In the tooth pattern collection step S2 of the new patient, as in the tooth pattern collection step S1 of the existing patient, the mouth of the new patient is photographed using a 3D optical scanner, and the shape of the tooth and the state of the dentition are acquired as data. do. The person in charge transmits the orthodontic treatment information 31 of the new patient including the person ID and the pretreatment tooth type information from the person in charge terminal device 10 to the orthodontic treatment support device 20. The information collecting unit 21 stores the obtained orthodontic treatment information 31 (pretreatment tooth type information) of the new patient in the storage unit 22.

The similarity calculation step S3 is a step of calculating the similarity based on the pretreatment tooth type information of the existing patient and the pretreatment tooth type information of the new patient. The similarity calculation unit 23 may store, for example, all the calculated similarities and the IDs of existing patients with the similarities in the storage unit 22 as orthodontic treatment information 31 for new patients, and the similarity is high. The IDs and similarities of the existing patients up to the top three may be stored in the storage unit 22 as the orthodontic treatment information 31 of the new patient. Further, the similarity calculation unit 23 (orthodontic treatment support device 20) displays, for example, the orthodontic treatment information 31 of the top three existing patients with high similarity on the person in charge terminal 10. The similarity calculation unit 23 may display only the information having the highest similarity on the person in charge terminal 10, or may display up to the top ten.

In the treatment plan providing step S4, the person in charge extracts the new patient by the similarity calculation step S3, and the display unit 12 of the person in charge terminal device 10 displays the orthodontic treatment information of one or more existing patients. It is a step of providing orthodontic treatment information 31 including an orthodontic treatment plan by displaying 31. For example, the person in charge selects the orthodontic treatment information 31 of the existing patient having the highest similarity, and based on the ideal tooth type information and the orthodontic treatment plan contained in the selected orthodontic treatment information 31, the new patient Ideal tooth type information and orthodontic treatment plan can be determined.

If the degree of similarity between the tooth patterns at the start of treatment is high as in Example 1, the orthodontic treatment plan of the existing patient can be used as a reference for the orthodontic treatment plan of the new patient. In other words, if the degree of similarity between tooth patterns at the start of treatment is high, the movement of teeth during orthodontics tends to be the same, so we provide high-quality orthodontic treatment plans, etc. using this tendency. can do. As a result, it is possible to support the orthodontic treatment of a new patient by providing information on an existing patient as a reference, regardless of the skill of the person in charge.

If all the calculated similarities are low, treatment is likely to be difficult, and for example, treatment with an orthodontist can be recommended to new patients.

On the other hand, when there are a plurality of existing patients having the same similarity, more accurate information (information matching the new patient) can be provided from among the high similarity by incorporating the similarity correction described above.

[Example 2]
Next, Example 2 of the present invention will be described. The second embodiment differs from the first embodiment in that the "achievement level" is used. As shown in FIG. 3, the orthodontic treatment support method according to the second embodiment is similar to the existing patient's tooth pattern collecting step S11, the existing patient's achievement calculation step S12, and the new patient's tooth pattern collecting step S13. A degree calculation step S14, a treatment plan provision step S15, and a new patient achievement degree calculation step S16 are performed.

The tooth pattern collecting step S11 of the existing patient is the same as the tooth pattern collecting step S1 of the existing patient in Example 1. The achievement degree calculation step S12 of the existing patient is a step of calculating the achievement degree based on the orthodontic treatment information 31 of the existing patient. The similarity calculation unit 23 reads out the ideal tooth type information and the post-treatment tooth type information in the orthodontic treatment information 31 for each existing patient, and calculates the similarity between the two. The degree of similarity is the "achievement level" for quantitatively grasping the degree of achievement as an orthodontic treatment. The similarity calculation unit 23 stores the calculated achievement level as orthodontic treatment information 31 in the storage unit 22 in association with the existing patient. When the second embodiment is executed at the time when the existing patient is a new patient, the calculation of the achievement degree is already performed by the achievement degree calculation step S16 of the new patient described later.

The tooth pattern collecting step S13 and the similarity calculation step S14 of the new patient are the same as the tooth pattern collecting step S2 and the similarity calculation step S3 of the new patient in Example 1. In the treatment plan providing step S15, the person in charge refers to the orthodontic treatment information 31 of the existing patient extracted in the similarity calculation step S14 and the achievement level of the existing patient for the new patient, and the treatment plan and the like. Is the process of providing.

The achievement degree calculation step S16 of the new patient reads out the ideal tooth type information of the new patient and the post-treatment tooth type information after the treatment of the new patient is completed, and calculates the similarity between the two. After the treatment of the new patient is completed, the person in charge acquires the post-treatment tooth type information using a 3D optical scanner. The information collecting unit 21 stores the post-treatment tooth type information of the new patient in the storage unit 22. The similarity calculation unit 23 reads out the ideal tooth pattern information of the new patient and the post-treatment tooth pattern information, calculates the similarity between the two, and causes the person in charge terminal 10 to display the calculation result.

Even with the second embodiment described above, substantially the same effect as that of the first embodiment can be obtained. Here, according to the second embodiment, since the "achievement level" is included in the orthodontic treatment information 31 of the existing patient, the existing patient having a high "achievement level" from the plurality of extracted information. You can refer to the orthodontic treatment plan of. This makes it possible, for example, to select information on existing patients with a high degree of achievement when there are multiple existing patients with the same similarity and these are different orthodontic treatment plans, and the quality is high for new patients. Information can be easily provided.

Further, in the achievement degree calculation step S16 of the new patient, after the treatment of the new patient is completed, the achievement degree of the new patient is calculated, so that the data including the achievement degree can be stored in the storage unit 22. .. As a result, high-quality data can be stored in the storage unit 22.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments and can be appropriately modified without departing from the gist of the present invention. For example, the control unit 13 of the person in charge terminal device 10 may function as the orthodontic treatment support device 20.
