In this way, various support devices are being developed in the field of orthodontic treatment.

JP2020-036755A

In orthodontic treatment, many devices have been developed to assist dentists in their treatment. For example, intraoral scanners and dental CT devices have recently become widespread. However, most of these devices do nothing more than acquire data inside the patient's oral cavity or draw a highly visible picture of the inside of the oral cavity, and it remains unclear what kind of treatment to perform using this information. However, the current situation is that it still depends on the ability of the dentist.

The present invention has been made to solve these problems, and provides an orthodontic support program that supports many dentists in formulating treatment plans so that they can perform appropriate orthodontic treatment. It is.

The present invention will be described below through embodiments of the invention, but the claimed invention is not limited to the following embodiments. Furthermore, not all of the configurations described in the embodiments are essential as means for solving the problem.

FIG. 1 is a diagram showing a system environment in which an orthodontic support program according to this embodiment is used. The orthodontic support program according to the present embodiment is installed and executed as an orthodontic support application in the support device 100, which is a PC, for example. The support device 100 functions as an orthodontic support device when a processor (CPU: Central Processing Unit) constituting the computer executes an installed orthodontic support application.

The support device 100 is connected to a data server 200 via, for example, a LAN (Local Area Network). The data server 200 stores numerical information and image data acquired by each of the data acquisition devices 300, which are various devices that acquire information regarding the condition of a patient's oral cavity. Examples of the data acquisition device 300 include a dental X-ray device, an intraoral scanner, and a dental CT device.

The support device 100 acquires target data from the data server 200 in accordance with a request from the orthodontic support application. Further, even when a data processing application other than the orthodontic support application is executed, target data is acquired from the data server 200 according to a request of the data processing application. For example, a data processing application may analyze data stored in the data server 200, and an orthodontic support application may use the analysis results. Further, the data itself stored in the data server 200 may be analysis data obtained by analyzing numerical information or image data obtained from the data acquisition device 300.

The orthodontic support application executed by the support device 100 visually presents the processing results to the user who is a dentist via the display monitor 110 connected to the support device 100, and displays information necessary for calculation processing. or request information. The input device 120 connected to the support device 100 is used by the user to input execution instructions and information necessary for calculation processing to the orthodontic support application.

In this embodiment, an example will be described in which an orthodontic support application installed on a PC by a user is executed, but the support device 100 is not limited to a PC, and may be a tablet terminal or the like. For example, if the cloud server executes an orthodontic support application and displays the processing results on a tablet terminal, the cloud server functions as an orthodontic support device. Note that the following explanation uses an example of a display screen when processing results processed by the support device 100, which is a PC, is displayed on the display monitor 110, but the display mode may vary depending on the information terminal used. It may be changed as appropriate.

FIG. 2 is a hardware configuration diagram of the support device 100 and main peripheral devices. The support device 100 is mainly connected to the data server 200, the display monitor 110, and the input device 120 as described above. The display monitor 110 is configured by, for example, a liquid crystal panel, and functions as a display unit that visually displays the video signal output from the support device 100. The input device 120 is a device for inputting instructions and information given to the support device 100 by the user. The input device 120 is, for example, a keyboard or a mouse, and may also be a touch panel superimposed on the display monitor 110, a voice instruction device, or the like.

The support device 100 mainly includes a processing section 130, a storage section 140, and a communication unit 150. The processing unit 130 is a processor (CPU) that controls the support device 100 and executes programs. The processor may be configured to cooperate with an arithmetic processing chip such as an ASIC (Application Specific Integrated Circuit) or a GPU (Graphics Processing Unit). In particular, the processing unit 130 executes various processes related to orthodontic support according to an orthodontic support program stored in the storage unit 140 or sent from an external device.

The storage unit 140 is a nonvolatile storage medium, and is configured by, for example, an HDD (Hard Disk Drive). In addition to programs for controlling and processing the support device 100, the storage unit 140 can store various parameter values, functions, lookup tables, learned models, etc. used for control and calculation. The storage unit 140 also stores a database of patient information including patient attribute information and treatment information. Note that the patient information database may be stored in a storage medium included in a network device such as the data server 200.

The communication unit 150 is responsible for exchanging data with the data server 200, and is configured by, for example, a LAN unit. The communication unit 150 exchanges information with the data server 200 under the control of the processing section 130.

The processing unit 130 also plays a role as a functional calculation unit that executes various calculations according to the processing instructed by the orthodontic support program. The processing unit 130 can function as an acquisition unit 131, a reception unit 132, a calculation unit 133, and an output unit 134. The acquisition unit 131 cooperates with the communication unit 150 to request necessary data from the data server 200 and acquires data sent from the data server 200 in response to the request instruction.

The reception unit 132 receives instructions and numerical values input by the user via the input device 120. Although specifically described later, the reception unit 132 mainly includes an observation value reception unit that accepts input of observation values observed for a target patient according to instructions and numerical values received from a user, and an observation value reception unit that receives input of observation values observed for a target patient, and an orthodontic treatment It functions as a target-related value reception unit that receives target-related values such as target movement amount.

The calculation unit 133 calculates the amount of difference to be corrected between the reference molars of the upper and lower jaws on the left and right sides, respectively, based on the observed values and target-related values, and calculates the difference to be corrected between the reference molars of the upper and lower jaws on the left and right sides, respectively. Quantities and the expected movement amount of each reference molar are calculated. A specific calculation method will be described later. The output unit 134 outputs information to be displayed on the display monitor 110 to the display monitor. Furthermore, when an external device requests output of calculation results, etc., the output is output to the external device via the communication unit 150. The output unit 134 arranges and displays, for example, the observed value, the amount of difference, the expected amount of movement, etc. in the window of the orthodontic support application displayed on the display monitor 110.

FIG. 3 is a diagram showing the entire application window 500 of the orthodontic support application. The application window 500 is a GUI (Graphical User Interface) screen displayed on the display monitor 110 while the orthodontic support application is being executed. In particular, FIG. 3 shows an example of an application window 500 that reads patient information specified by the user, accepts input from the user, and presents the calculation results.

The illustrated application window 500 mainly includes patient information 510, a calculation button 521, a save button 522, an observed value area 530, a goal-related value area 540, and a calculation result area 550. Patient information 510 indicates the ID and attribute information of a patient designated by the user. The calculation button 521 is
This is an instruction button for instructing the calculation unit 133 to start calculation. The save button 522 is an instruction button for instructing to save the calculation results and written diagnostic comments in association with patient information.

The observed value area 530 mainly displays numerical values of numerical information and images of image data obtained by the obtaining unit 131, and is used by the receiving unit 132 as an observed value receiving unit to receive input of specific observed values from the user. This is an area that displays an input box. The goal-related value area 540 is an area where the reception unit 132, as a goal-related value reception unit, mainly displays an input box for receiving input of a goal-related value to be simulated by the user when determining a treatment policy. The calculation result area 550 is an area that mainly displays the calculation results calculated by the calculation unit 133. The specific display contents of the observation value area 530, target-related value area 540, and calculation result area 550 and related processing calculations will be explained in order.

FIG. 4 is a diagram showing an observed value area 530 in the application window 500. In the observed value area 530, numerical values of numerical information and images of image data regarding the designated patient acquired by the acquisition unit 131 are displayed. Specifically, maxillary dentition images, occlusal side-view images, etc. that have been imaged with a dental CT device or an intraoral scanner and have been subjected to CG processing are displayed together with related numerical values. Relevant numbers are shown enclosed in boxes.

If the observed values are already stored in the data server 200, the numerical values acquired by the acquisition unit 131 are displayed as they are. In this embodiment, an input box format that accepts corrections is adopted so that even such observed values can be corrected by a user who is a dentist to the results of detailed analysis using a dedicated app. is displayed.

On the other hand, among the observed values, those that are not stored in the data server 200 and require the input of the analysis results by the user who is a dentist, or those that are stored in the data server 200 are subject to the calculation process described below. For items that are particularly necessary, highlighted input boxes are placed to increase visibility and prompt the user to input or confirm the input. In this embodiment, the identifier is emphasized by superimposing the identifier surrounded by a frame inside the input box. The identifier is expressed by alphabets and numbers. For example, regarding the amount of CO-CR deviation, the identifier "a1" is superimposed on the input box for the right observed value, and the identifier "a2" is superimposed on the input box for the left observed value. There is. Note that the display for improving visibility may appear only when the mouse cursor is brought close, for example, or the frame of the input box may be decorated instead of the identifier, or a specific icon may be placed nearby.

In this embodiment, the observed value represented by the highlighted input box is the amount of deviation between the central occlusal position and the reference molar at the central position on each of the left and right sides of the lower jaw, which is expressed as "CO-CR deviation amount" in the figure. a1, a2), and the lingual cusp of the second premolar of the upper jaw and the second premolar and first molar of the mandible on the left and right, respectively, whose input boxes are superimposed on the left and right occlusal side view images. The amount of deviation between the parts that contact each other (b1, b2), the depth of the speed curve on the left and right sides of the mandible (c1, c2), the amount of movement (d) according to the growth of the patient's mandible, and the auxiliary line. An input box is provided beside the superimposed maxillary dentition image, which is the amount of deviation (e) in the mesio-distal direction between the left and right reference molars of the maxilla with respect to the facial midline.

In this embodiment, the first molar is used as the reference molar for the CO-CR deviation amount (a1, a2). In other words, the user can determine the amount of deviation (a1) of the right first molar between the central occlusion position (CO) and the central position (CR), and the deviation amount of the left first molar. Input the amount of deviation (a2) with the mesial position as a minus value. In this embodiment, among the observed values acquired by the acquisition unit 131 from the data server 200, the height distance from the FH plane to the mesial buccal cusp of the left and right first molars and the central incisor, the upper and lower anterior teeth, The amount of deviation in the midline of the area is displayed as a reference value superimposed on the CT image.

The amount of deviation between the lingual cusp of the second premolar in the upper jaw and the area where the second premolar and first molar in the mandible contact each other (b1, b2) can realistically be based on these teeth. Although desirable, other teeth may be used as a reference depending on the patient's condition. In that case, in the calculation formula to be described later, the amount of difference between the distal and mesial positions with respect to other teeth as a reference is taken into consideration. The depths (c1, c2) of the Spee curves on the left and right sides of the mandible are the depths at which the envelope of the cusp forms a concave curved line when the dentition of the mandible is viewed from the side. In the present embodiment, among the observed values acquired by the acquisition unit 131 from the data server 200, the amounts of crowding on the left and right sides of the upper and lower jaws are displayed as reference values between the left and right occlusal side-view images.

The amount of movement (d) of the patient's lower jaw in response to growth should be considered especially when the patient is a minor in the growth period, and the user who is a dentist should set an appropriate value according to the patient's characteristics. input. Specifically, if the patient's mandible is expected to grow downward and forward, the mandibular molars will also move forward, so the user predicts and inputs the amount of movement of the mandibular first molars. .

In this embodiment, the reference molars for the mesiodistal deviation amount (e) between the left and right reference molars of the upper jaw with respect to the facial median are the first molars on both the left and right sides. That is, the user inputs the amount of deviation of the first molar on the right side with respect to the first molar on the left side, with the mesial position being set as a minus. In this embodiment, an maxillary dentition image, which is a CT image, is displayed near the input box and an auxiliary line is superimposed thereon to help the user understand which deviation amount is to be input.

In addition, at the bottom of the observed value area 530, among the observed values acquired by the acquisition unit 131 from the data server 200, observed values related to tooth width are displayed as reference values. Specifically, the tooth width of each tooth constituting the maxillary right side (UR) tooth row and its total, the tooth width of each tooth constituting the maxillary left side (UL) tooth row and its total, and the mandibular right side (DR) The tooth width of each tooth constituting the dentition and the total thereof, and the tooth width of each tooth constituting the dentition of the left side of the lower jaw (DL) and the total thereof are displayed. In this embodiment, all numerical values are expressed in units of mm, but other units may be selected.

FIG. 5 is a diagram showing a goal-related value area 540 in the application window 500. In the goal-related value area 540, an input box is displayed in which the user can input goal-related values by trial and error when determining a treatment policy. As part of such an input box, an input box is included that accepts an input of a target movement amount for the reference molars of the upper and lower jaws on each of the left and right sides of the patient. The position of the maxillary anterior tooth as a treatment target is calculated from the current ANB angle (in the upper right figure of the calculation result area 550, which will be described later, the treatment target of the position of the anterior tooth on the cephalometric analysis by Dr. Steiner (USA) is referred to). In order to bring the target value of the maxillary anterior teeth closer to the current position of the maxillary anterior teeth, check the amount of anterior retraction of the anterior teeth, decide whether to extract the premolars or not, and set the distal-mesial movement of the molars.

In this embodiment, each first molar is used as the reference molar. That is, the user can set, for example, TAD (Temporary Anchorage If the tooth is to be moved distally using a device (Device), enter a positive value as the expected amount of movement; for example, if the tooth is to be moved mesially due to a tooth extraction, enter a negative value as the expected amount of movement. However, since the assumed movement amounts of the maxillary right first molar and left side first molar are usually the same value, in this embodiment, they are combined into one input box as the maxillary molar movement amount (f1), For the lower jaw, input boxes are provided for the amount of movement of the lower right molar tooth (f2) and the amount of movement of the lower left molar tooth (f3), respectively.

Furthermore, in this embodiment, input boxes are provided for specifying the tooth extraction site for each of the right and left sides of the upper jaw and the right and left sides of the lower jaw. If the user wants to improve crowding or move the tooth mesially by extracting a tooth, the user refers to the observed value regarding the tooth width displayed in the observed value area 530 and enters the number of which tooth to extract at the corresponding extraction site. Enter in the input box. For example, in the illustrated example, the fourth tooth on the right side of the upper jaw and the fourth tooth on the left side of the upper jaw are input as tooth extraction sites. In this embodiment, when the user enters a number in the input box for the tooth extraction site, the amount of movement of the upper molar tooth (f1), the amount of movement of the lower right molar tooth (f2), and the amount of movement of the lower left molar tooth (f3) are input. The value in the box is updated to the amount of movement when the tooth is extracted.

FIG. 6 is a diagram showing a calculation result area 550 in the application window 500. If the acquisition unit 131 acquires observed values from the data server 200 and the reception unit 132 accepts input of specific observed values and goal-related values from the user, and then the press of the calculation button 521 is detected, the calculation unit 133 performs calculation processing. Execute. The calculation result area 550 mainly displays the calculation results. The calculation result area 550 includes a first output frame 551 that displays the amount of difference to be corrected between the reference molars of the upper and lower jaws on the left and right sides, which are the results of the calculation processing, and a prediction of the reference molars of the upper and lower jaws on the left and right sides, respectively. It includes a second output frame 552 that displays the amount of movement. In addition, the calculation result area 550 contains the cephalometric analysis obtained values as observed values, and the expected correction values of these values when the target movement amount is achieved (the position of the front teeth calculated from ANB) as the result of calculation processing. ) are also displayed.

In this embodiment, each first molar is used as the reference molar for calculating the amount of difference to be corrected. That is, the maxillary right first molar calculated by the calculation unit 133 based on the observation value acquired by the acquisition unit 131, the specific observation value received by the reception unit 132, and the target-related value received by the reception unit 132. The first output is the amount of difference to be corrected between the first molar on the right side of the lower jaw (R difference amount), and the amount of difference to be corrected between the first molar on the left side of the upper jaw and the first molar on the left side of the mandible (L difference amount). It is displayed in a frame 551.

In this embodiment, the target-related values, maxillary molar movement amount (f1), mandibular right molar movement amount (f2), and mandibular left molar movement amount (f3), are not input or all "0" is input. When the calculation button 521 is pressed in this state, the amount of difference to be corrected between the left and right sides in the current patient's condition is calculated, and the results are displayed. At this time, the numbers in each input box are
(R difference amount) = (b1) - | (c1) | /5 + (a1)
(L difference amount) = (b2) - | (c2) | /5 + (a2)
It is calculated as Here, the value of multiplying the depth of Speech curvature (c1, c2) by 1/5 to move distally is based on empirical values, and this value is configured to be modified as appropriate depending on the inclination of the patient's teeth. It's okay.

On the other hand, if the calculation button 521 is pressed while the target-related values, maxillary molar movement amount (f1), mandibular right molar movement amount (f2), and mandibular left molar movement amount (f3), are input, each of the input The remaining difference amount when the target movement amount is achieved is calculated, and the result is displayed. At this time, the numbers in each input box are
(R difference amount) = (b1) - | (c1) | /5 + (a1) + (f1) - (f2)
(L difference amount) = (b2) - | (c2) | /5 + (a2) + (f1) - (f3)
It is calculated as Therefore, first, the amount of difference to be corrected between the left and right sides in the current patient's condition is calculated and the results are displayed. When a value other than "0" is input to at least one of the amounts (f3) and the calculation button 521 is pressed, the calculation unit 133 executes the calculation again, and the calculation result is displayed based on the input target movement amount. Updated with the remaining difference amount in case it is achieved.

Note that in this embodiment, only numerical values that significantly contribute to the results of the R difference amount and L difference amount are used as the basis for calculation, but when performing more precise calculations, other observed values and target-related values may be used as the basis for calculation. May be used. Further, the calculation formula may be changed as appropriate depending on the adoption of such numerical values.

In this embodiment, the first molars are used as the reference molars for calculating the expected movement amounts of the upper and lower jaws on the left and right sides, respectively. That is, the expected movement amount (UR movement amount) of the upper right first molar is calculated by the calculation unit 133 based on the observation value acquired by the acquisition unit 131 and the specific observation value and target-related value received by the reception unit 132. ), the expected amount of movement of the mandibular right first molar (DR movement amount), the expected movement amount of the maxillary left first molar (UL movement amount), and the expected movement amount of the mandibular left first molar (DL movement amount). Each is displayed in the second output frame 552.

In this embodiment, when the target-related values maxillary molar movement amount (f1), mandibular right molar movement amount (f2), and mandibular left molar movement amount (f3) are input and the calculation button 521 is pressed, each The expected amount of movement is calculated and the result is displayed. At this time, the numbers in each input box are
(UR movement amount) = (f1)
(UL movement amount) = (f1) + (e)
(DR movement amount) = (f2) + | (c1) | /5
(DL movement amount) = (f3) + | (c2) | /5
It is calculated as

The cephalometric analysis obtained values as observed values indicate the inclination angle of the maxillary anterior teeth, the inclination angle of the mandibular incisors, the angle between the maxillary incisors and the mandibular incisors, the amount of protrusion of the maxillary incisors, and the amount of protrusion of the mandibular incisors. The angle is expressed in degrees, and the amount of protrusion is expressed in mm. After entering all the data, a numerical value will also be entered in the treatment prediction value. If the value is large, the protrusion of the lips can be improved by distal movement of the upper molars or extraction of the premolars. Here, if there are changes such as growth or deviations in CO-CR, the ANB (anterior and posterior evaluation of the upper and lower jaw) values will change. Target values for the front teeth of the upper and lower jaws are generated from the numerical values, and the input values are preferably adjusted so as to approach these values. Furthermore, in the evaluation of the target value, it may be added that it is set inside the E-Line (aesthetic line) connecting the nose and the chin.

In this embodiment, when the target-related values maxillary molar movement amount (f1), mandibular right molar movement amount (f2), and mandibular left molar movement amount (f3) are input and the calculation button 521 is pressed, these values are The predicted correction values of the angle and protrusion amount are also calculated, and each predicted correction value (the position of the anterior teeth calculated from the ANB) is displayed in an area adjacent to the display area of the cephalometric analysis acquired values. Note that in this embodiment, the observed value and the predicted corrected value are displayed in separate display areas, but when the calculation button 521 is pressed and the calculated result is obtained, the observed value is updated to the predicted corrected value. It doesn't matter what form it takes.

In this way, by displaying the observed value area 530, the target-related value area 540, and the calculation result area 550 on the same screen, the user, who is a dentist, can focus on which observed value and determine what type of target value. It is possible to repeatedly check the calculation results of the correction difference amount and expected movement amount while determining by trial and error the range to be determined. Therefore, even an inexperienced dentist can devise a more appropriate treatment policy for orthodontic treatment.

Next, a description will be given of a processing procedure executed by the processing unit 130 according to instructions from the orthodontic support program. FIG. 7 is a flow diagram showing the processing procedure of the processing executed by the processing unit 130. The illustrated flow starts from the point in time when the user specifies a target patient.

The acquisition unit 131 acquires various data regarding the designated target patient from the data server 200 in step S101. The various data acquired here include numerical information including observed values of the target patient, image data related to the observed values, and the like. The output unit 134 arranges these observed values and images of image data in accordance with the display mode of the application window 500 and displays them on the display monitor 110.

Proceeding to step S102, the accepting unit 132 accepts a specific observed value input by the user. Furthermore, in step S103, the receiving unit 132 receives the goal-related value input by the user. Step S102 and step S103 may be performed in reverse order or may be performed in parallel.

When the calculation button 521 is pressed, the process advances to step S104, and the calculation button 521 calculates the correction difference amount, expected movement amount, etc. In step S105, the output unit 134 arranges the calculation results calculated by the calculation unit 133 in accordance with the display mode of the application window 500 and displays them on the display monitor 110.

In step S106, the processing unit 130 checks whether the user has pressed the save button 520. If the save button 520 has been pressed, it is determined that a save instruction has been given, and the process advances to step S107. If the save button 520 has not been pressed, the process returns to step S102 and processes related to recalculation are executed.

Proceeding to step S107, the processing unit 130 compiles the calculation results into data according to a predetermined format, and transmits the data as one of the various data of the target patient to the data server 200 for storage. Note that the user can check the results of the arithmetic processing performed in the past by reading them from the data server 200 and displaying them on the display monitor 110. When the storage process is completed, the processing unit 130 ends the series of processes.

The present embodiment has been described above, but the user, who is a dentist, determines by trial and error which observation value to focus on and what type of target value and within what range. As long as it is an embodiment in which the calculation results of the correction difference amount and the expected movement amount can be repeatedly confirmed, various specifications other than the above specifications can be adopted. For example, in this embodiment, the observed value area 530, the goal-related value area 540, and the calculation result area 550 are arranged side by side in the application window 500, but each may be displayed in a pop-up window. Furthermore, when the user confirms observed values or determines target-related values, another application may be automatically launched so that related information can be confirmed in a small window.
