Description

Technical Field

[0001] This invention relates to image analysis and processing technology, and more specifically to digital dental diagnosis and treatment planning technology based on image analysis. Background Technology

[0002] Dental treatments using digital dental software (e.g., orthodontics, prosthodontics, dentures, etc.) are performed through patient data acquisition, treatment planning, device (e.g., prosthesis) fabrication, treatment, treatment outcome confirmation, or similar procedures. For orthodontics, in particular, teeth need to be ideally set up by establishing an orthodontic diagnosis and treatment plan based on the patient's data before orthodontic treatment.

[0003] When using dental software to process teeth, manipulators can be displayed for each tooth in the patient's image data shown on the screen, and the user can rotate or move each tooth by manipulating the manipulators displayed on the screen. When tooth movement or rotation is required, the tooth movement based on the user's manipulation is visualized and displayed on the screen when the user selects and manipulates a single tooth.

[0004] At the same time, when functions such as tooth extraction, interproximal enamel reduction (IPR), and tooth fixation (which are the main orthodontic techniques) are required, the corresponding functions need to be performed by entering a separate page. These functions are performed separately from the tooth movement and rotation steps. Summary of the Invention

[0005] Technical issues

[0006] The present invention aims to provide a digital dental setting method and apparatus that minimizes additional operations performed by the user and increases ease of use when the user operates dental software.

[0007] Technical solutions

[0008] One aspect of the present invention provides a digital dental setting method performed by a digital dental setting device, the method comprising: displaying dental image data; receiving selection input for a predetermined tooth via manipulation by a user on the displayed dental image data; displaying a plurality of manipulators for at least one of fine-tuning functions and treatment techniques on an annular guide interface surrounding the selected tooth; and performing dental setting using the plurality of manipulators, wherein the fine-tuning functions include at least one of tooth movement and tooth rotation, and the treatment techniques include at least one of tooth extraction, tooth fixation, and interproximal enamel removal.

[0009] During the operation of the display manipulator, the tooth movement interface and tooth rotation interface can be divided into a collision compensation interface and a collision ignore interface and displayed. The collision compensation interface is used to compensate for the collision between the selected tooth and the adjacent teeth, and the collision ignore interface is used to ignore the compensation for the collision between the selected tooth and the adjacent teeth.

[0010] During the operation of the display manipulator, the collision compensation interface and the collision ignore interface can be displayed at positions symmetrical to each other relative to the center of the guide interface.

[0011] During the operation of the manipulator, at least one of the following images can be displayed: a frontal image of the teeth, an occlusal surface image of the teeth, and a lateral image of the teeth, and the manipulator can be displayed in each image.

[0012] During the operation of displaying the manipulator, at least two of the following images can be displayed together: a frontal image of the teeth, an occlusal surface image of the teeth, and a lateral image of the teeth. The manipulator can be displayed in each image. During the operation of performing tooth setting using the manipulator, when the manipulator in the predetermined image is manipulated by the user, the result of the manipulation can be reflected in at least one other image in real time and displayed.

[0013] Performing tooth setting using a manipulator may include: fine-tuning a selected tooth using the manipulator via user manipulation; determining whether the selected tooth collides with adjacent teeth during fine-tuning; and reflecting the expected collision and compensating for the amount of movement of adjacent teeth. Performing tooth setting using a manipulator may also include: visualizing and displaying the direction of collision and the amount of overlap when a collision occurs between the selected tooth and adjacent teeth.

[0014] When performing tooth setting operations using a manipulator, if the selected tooth collides with an adjacent tooth during fine-tuning of the selected tooth, a compensating movement can be performed on the adjacent tooth along an arc in the same direction as the selected tooth, according to the amount of overlap, within the range of the collision between the selected tooth and the adjacent tooth.

[0015] During operation of the display manipulator, the position of the rotation center point candidate can be displayed, and rotational movement will be performed around the rotation center point candidate to rotate the selected tooth using the manipulator. In the operation of performing tooth setting using the manipulator, a predetermined rotation center point can be selected from the displayed rotation center point candidate by the user's operation, and the selected tooth can be rotated around the selected rotation center point.

[0016] During operation of the display manipulator, the position of the rotation center point candidate for performing rotational movement around it to rotate the selected tooth using the manipulator can be displayed, and a preset basic center point can be suggested among the center point candidates. During operation of tooth setting using the manipulator, the preset basic rotation center point can be changed to another predetermined rotation center point among the displayed rotation center point candidates by the user's manipulation, and the selected tooth can be rotated around the changed rotation center point.

[0017] During the operation of the display manipulator, a tooth extraction interface can be displayed, and when the user selects the tooth extraction interface for the selected tooth through manipulation, the selected tooth can be deleted, and the portion where the selected tooth has been deleted can be displayed as an empty space.

[0018] During operation of the display manipulator, a tooth fixation interface can be displayed, and when performing tooth settings using the manipulator, the selected tooth can be fixed when the user selects the tooth fixation interface for the selected tooth through manipulation.

[0019] The manipulator can display the proximal enamel removal interface, and when performing tooth settings using the manipulator, when the amount of proximal enamel removal is input via the proximal enamel removal interface for the selected tooth through the user's manipulation, at least one of the mesial and mesiodistal surfaces of the selected tooth can have the input amount of proximal enamel removal removed and displayed.

[0020] The adjacent surface deglazing interface may include at least one of the following: a text box interface for receiving deletion values ​​from the user, and an increase / decrease interface for increasing and / or decreasing the amount of adjacent surface deglazing by user selection.

[0021] Performing tooth settings using a manipulator may also include at least one of the following: displaying the selected tooth and the tooth width changed after interproximal enamel removal and the interproximal enamel removal; and analyzing the tooth width changed after interproximal enamel removal and providing the results of the analysis.

[0022] Another aspect of the present invention provides a digital tooth setting method performed by a digital tooth setting device, the method comprising: displaying dental image data; receiving a selection input for a tooth via user manipulation of the displayed dental image data; displaying a tooth fine-tuning interface, including at least one of a tooth movement interface and a tooth rotation interface, on a ring-shaped guide interface surrounding the selected tooth; performing tooth fine-tuning using the tooth fine-tuning interface via user manipulation; determining whether the selected tooth collides with an adjacent tooth during tooth fine-tuning; and reflecting the expected collision at the time of collision and compensating for the amount of movement of adjacent teeth.

[0023] Another aspect of the present invention provides a digital dental setting device, comprising: an output unit configured to display a screen including dental image data; an input unit configured to receive user manipulation signals; and a control unit configured to, when receiving selection input for a predetermined tooth via user manipulation of the dental image data displayed on the screen through the input unit, display a plurality of manipulators for at least one of fine-tuning functions and treatment techniques on an annular guide interface surrounding the selected tooth through the output unit, and perform dental setting using the plurality of manipulators, wherein the fine-tuning function includes at least one of tooth movement and tooth rotation, and the treatment techniques include at least one of tooth extraction, tooth fixation, and interproximal enamel removal.

[0024] Beneficial effects

[0025] According to the digital tooth setting method and apparatus using a manipulator according to the embodiment, the manipulator can be arranged on a ring-shaped guide interface, and therefore, when the user manipulates the manipulator, additional manipulations by the user can be minimized and the ease of use can be increased.

[0026] When moving a single tooth using a manipulator, the anticipated collision with adjacent teeth can be visualized and displayed. Adjacent teeth reflecting the anticipated collision can move along with the tooth, thus minimizing additional manipulation by the user and increasing ease of use. For example, there is no need to additionally move adjacent teeth due to collisions with them when a single tooth is moved or rotated. Tooth setting procedures can be easily performed based on the actual tooth movement.

[0027] When rotating a selected tooth using a manipulator, the result of the tooth rotation varies depending on the rotation center point. As the position of the rotation center point changes, a position reflecting the actual tooth axis can be specified. This allows users to check information about the rotation center point of the selected tooth and change its position, increasing ease of use.

[0028] As another example, by including and providing an interface for performing treatment techniques (e.g., tooth extraction, interproximal enamel removal, or tooth fixation), fine-tuning functions, including tooth movement and rotation, as well as treatment technique functions, can be applied in a single screen within the same step. Therefore, since fine-tuning and treatment techniques can be applied simultaneously, additional steps required by the user are reduced, and ease of use is increased.

[0029] When using manipulators to set teeth, not only can simple fine adjustments be made, but extractions, tooth fixation, and interproximal enamel removal, which are orthodontic treatment techniques, can also be applied, thus increasing the accuracy of treatment planning and user convenience. Because tooth movement and treatment techniques are used simultaneously, treatment results similar to those of actual treatment can be expected.

[0030] When using a manipulator to set teeth, fine-tuning and treatment techniques can be applied in the same step, reducing the workload of the software. Attached Figure Description

[0042] The advantages and features of the present invention, as well as the methods for achieving these advantages and features, will become clear from the accompanying drawings and the detailed description of the embodiments described below. However, the present invention is not limited to the embodiments disclosed below, but can be implemented in various different forms. These embodiments are provided to fully illustrate the embodiments and the scope of the invention to those skilled in the art. The scope of the invention is defined only by the appended claims. Throughout the specification, similar reference numerals refer to similar elements.

[0043] Furthermore, when describing embodiments of the present invention, detailed descriptions of known technologies related to the present invention will be omitted if it is determined that such detailed descriptions unnecessarily obscure the subject matter of the present invention. Some terms described below are defined by consideration of their function in the present invention, and their meanings may vary depending on, for example, the intent or habit of the user or operator. Therefore, the meanings of the terms should be interpreted within the scope of this specification.

[0044] In this context, it will be recognized that each block of the block diagram and the combination of steps in the flowchart can be executed by computer program instructions (execution engine). Since computer program instructions can be loaded into the processor of a general-purpose computer, a special-purpose computer, or other programmable data processing device, the instructions executed by the processor of the computer or other programmable data processing device generate means for performing the functions described in the blocks of the block diagram or the steps of the flowchart.

[0045] Since computer program instructions can be stored in a computer-usable or computer-readable memory that can instruct a computer or other programmable data processing device to perform a function in a particular manner, the instructions stored in the computer-usable or computer-readable memory can produce an article of art that includes instruction means for performing the functions described in the blocks of a block diagram or the steps of a flowchart.

[0046] Since computer program instructions can also be installed in a computer or other programmable data processing apparatus, the instructions for performing a series of operational steps on a computer or other programmable data processing apparatus to generate a computer-implemented process to be executed on a computer or other programmable data processing apparatus can provide steps for performing the functions described in the blocks of a block diagram or the steps of a flowchart.

[0047] Additionally, each box or step may represent a portion of a module, segment, or code, which includes one or more executable instructions for performing a specified logical function. It should also be noted that in some alternative implementations, the functions mentioned in a box or step may not occur in sequence. For example, two boxes or steps shown consecutively may actually execute substantially simultaneously, or boxes may sometimes execute in reverse order based on their corresponding functions.

[0048] Various embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, embodiments of the present invention can be modified in several different ways, and the scope of the present invention is not limited to the embodiments described below. Embodiments of the present invention are provided to fully illustrate the invention to those skilled in the art.

[0049] Figure 1 This is a diagram illustrating the configuration of a digital tooth setting device according to an embodiment of the present invention.

[0050] Reference Figure 1 The digital dental setup device 1 performs dental setup design to assist in orthodontic, restorative, and prosthetic fitting procedures in actual dental practice. Dental setup design includes a series of processes: acquiring the patient's dental image data; performing simulations under software control using the dental image data for diagnosis and analysis to establish a treatment plan; and generating virtual dental setup data, in which teeth are set according to the established treatment plan. Dental setup can be applied to orthodontics, restorative procedures, prosthetics, etc. The patient's dental image data may include at least one of the following: computed tomography (CT) data, oral data, and facial data, or data acquired by matching two or more of CT data, oral data, and facial data.

[0051] The digital dental setting device 1 according to this embodiment may include an electronic device capable of executing a dental setting design program and a server communicating with the electronic device via a network. Examples of electronic devices include computers, laptop computers, tablet computers (PCs), smartphones, mobile phones, personal media players (PMPs), personal digital assistants (PDAs), etc.

[0052] Reference Figure 1 The digital tooth setting device 1 according to this embodiment includes a data acquisition unit 10, a storage unit 12, a control unit 14, an input unit 16, and an output unit 18.

[0053] The data acquisition unit 10 acquires dental image data from the patient. The dental image data required for treatment may include at least one of the following: CT data, oral cavity data, and facial data, or data acquired by matching two or more of CT data, oral cavity data, and facial data. In addition, the dental image data may also include cephalometric radiographs, panoramic data, cephalometric X-ray data, posteroanterior (PA) X-ray data, etc.

[0054] The scan data is data containing information about the actual teeth, including the damaged teeth. The scan data can be tooth model scan data obtained by scanning a plaster cast model that mimics the patient's mouth using a 3D scanner. As another example, the scan data can be oral scan data obtained by scanning the inside of the patient's mouth using a 3D intraoral scanner. The acquired scan data can be stored in storage unit 12.

[0055] CT data can be obtained by generating tomographic images of the patient's head using CT scans, segmenting the boundaries of the teeth in each tomographic image, and then combining the segmented images into a single image. The scan data and CT data include: images of the maxilla taken from below the maxilla with the patient's mouth open; images of the mandibular teeth taken from above the mandibular teeth with the patient's mouth open; images of localized areas taken with the patient's mouth closed; oral X-rays, etc. The acquired CT data can be stored in storage unit 12. The CT data can be in 3D format. Soft tissue information as external information about the face, skeletal structure information as internal information, and oral cavity information can be acquired using CT data and used in dental treatments.

[0056] For example, various types of data, such as information required for the operation of the digital tooth setting device 1 and information generated based on the operation, are stored in the storage unit 12. The storage unit 12 can provide the control unit 14 with the data required for data analysis performed by the control unit 14.

[0057] The output unit 18 displays a screen based on the operation of the control unit. For example, the output unit 18 may display dental image data and the manipulators on the dental image data. The process of creating an orthodontic treatment plan using dental software includes manipulating the manipulators displayed on the dental image to complete the following operations: moving a single tooth to the desired position, rotating a tooth, extracting a tooth, fixing a tooth, deleting a tooth, etc.

[0058] The input unit 16 receives user operation signals. For example, the input unit 16 receives user operation signals for performing tooth movement, tooth rotation, tooth extraction, tooth fixation, interproximal enamel removal, etc., based on tooth setting data displayed on the screen by the output unit 18.

[0059] When a user receives a selection input for a predetermined tooth via manipulation of dental image data displayed on the screen through input unit 16, control unit 14 provides a manipulator via output unit 18 around the selected tooth display, offering at least one of fine-tuning and treatment technique functions, and performs tooth setting using the manipulator. In this case, the user's manipulation for receiving the tooth selection input may include actions such as clicking with an input tool like a mouse or touching with a body part like a finger, or actions such as allowing the cursor of the input tool or the finger to remain on the corresponding tooth for a predetermined time period or longer. Simultaneously, the fine-tuning function may include at least one of tooth movement and tooth rotation. The treatment technique functions may include at least one of tooth extraction, tooth fixation, and interproximal enamel removal.

[0060] The control unit 14 can provide an interface on the guide screen for performing treatment techniques (e.g., tooth extraction, interproximal enamel removal, or tooth fixation). When the treatment technique function is operated separately from the functions of the guide screen, a separate page must be accessed and the corresponding function executed when needed. This results in the inconvenience of navigating through multiple screens and user discomfort due to reduced continuity during operation. To address this problem, the control unit 14 can provide an interface on the guide screen for performing treatment techniques (e.g., tooth extraction, interproximal enamel removal, or tooth fixation), thereby resolving the inconvenience of accessing separate screens.

[0061] The control unit 14 can visualize and display the expected collision with adjacent teeth when the selected tooth is finely adjusted using the manipulator, and also executes the movement of adjacent teeth that reflects the expected collision. If dental image data is displayed while ignoring collisions with adjacent teeth during manipulator operation, a collision may occur between the moving tooth and adjacent teeth when a single tooth moves and rotates to the position desired by the user. Additional movement of the single tooth to compensate for collisions with adjacent teeth is necessary, and despite the use of software, problems such as reduced working speed and increased workload due to tooth movement may occur.

[0062] To address the aforementioned issues, the control unit 14 can visualize and display the anticipated collision with adjacent teeth when the selected tooth is finely adjusted using a manipulator, and also executes the movement of adjacent teeth reflecting the anticipated collision. Therefore, additional manipulation by the user is reduced, and ease of use is increased. For example, there is no need for the additional movement of adjacent teeth due to collisions with adjacent teeth when a single tooth is moved or rotated. Based on the actual tooth movement, tooth setting procedures can be easily performed.

[0063] The control unit 14 can set or change the position of the rotation center point when the selected tooth is rotated using a manipulator. For example, when the position of the rotation center point changes, the position of the rotation center point reflecting the actual tooth axis can be specified, and thus the user can check information about the rotation center point of the selected tooth and change the position of the rotation center point, thereby increasing the ease of use.

[0064] In this implementation, the control unit 14 can apply fine-tuning functions, including tooth movement and tooth rotation, as well as treatment techniques within a single screen in the same step. In this case, since tooth fine-tuning and treatment techniques can be applied simultaneously, additional operations by the user are reduced, and ease of use is increased.

[0065] Figure 2 This is a flowchart illustrating a digital tooth setting method using a manipulator according to an embodiment of the present invention.

[0066] Reference Figure 2 The digital dental setting device can display dental image data (S410) and receive selection input for teeth through user manipulation of the displayed dental image data (S420).

[0067] Next, the digital dental setting device displays a plurality of manipulators on a guide interface surrounding the selected tooth, for at least one of the fine-tuning function and treatment technique function (S430). Here, the guide interface is an interface for arranging the plurality of manipulators and is configured in a ring around the tooth, with the plurality of manipulators arranged on the ring.

[0068] The fine-tuning functions include at least one of tooth movement and tooth rotation, and the therapeutic techniques include at least one of tooth extraction, interproximal enamel removal, and tooth fixation. The digital tooth setting device uses a manipulator to perform tooth setting (S440).

[0069] In the operation S440 of performing tooth setting using a manipulator, the digital tooth setting device can visualize and display the expected collision with adjacent teeth when moving a single tooth using the manipulator, and also performs movement of adjacent teeth that reflect the expected collision. Therefore, additional manipulation by the user is reduced, and ease of use is increased. Based on the actual tooth movement, tooth setting processing can be easily performed.

[0070] Therefore, in operation S430, which displays the manipulator on the guide interface, the digital tooth setting device can divide and display the tooth movement interface and the tooth rotation interface as a collision compensation interface and a collision ignore interface. The collision compensation interface compensates for the collision with adjacent teeth when the selected tooth collides with them, while the collision ignore interface ignores the collision and does not compensate for the collision with adjacent teeth even when a collision occurs.

[0071] In operation S440, which involves using a manipulator to perform tooth setting, the digital tooth setting device can perform fine-tuning of the selected tooth using the manipulator under the user's control. The digital tooth setting device can determine whether the selected tooth collides with adjacent teeth during fine-tuning, and can compensate for the amount of movement of adjacent teeth by reflecting the expected collision at the time of collision. Furthermore, the digital tooth setting device can visualize and display the direction of collision and the amount of overlap when the selected tooth collides with an adjacent tooth.

[0072] In the operation S440 of performing tooth setting using a manipulator, when the selected tooth collides with an adjacent tooth during tooth fine-tuning of the selected tooth, the digital tooth setting device can perform compensatory movement of the adjacent tooth along an arc in the same direction as the selected tooth by an overlap amount within the range of the collision between the selected tooth and the adjacent tooth (e.g., left maxilla, right maxilla, left mandible, or right mandible).

[0073] In operation S430, which displays the manipulator, the digital tooth setting device can display the position of a rotation center point candidate, around which a rotational movement is performed to rotate the selected tooth using the manipulator. Then, in operation S440, which uses the manipulator to perform tooth setting, the digital tooth setting device can select a predetermined rotation center point from the displayed rotation center point candidates through user manipulation, and rotate the selected tooth around the selected rotation center point.

[0074] As another example, in operation S430 of displaying the manipulator, the digital tooth setting device can display the position of a candidate rotation center point around which a rotational movement will be performed to rotate the selected tooth using the manipulator, and suggest a preset basic center point among the center point candidates. Then, in operation S440 of performing tooth setting using the manipulator, the digital tooth setting device can change the preset basic rotation center point to another predetermined rotation center point among the displayed rotation center point candidates through user manipulation, and rotate the selected tooth around the changed rotation center point.

[0075] In operation S430 of displaying the manipulator, the digital tooth setting device can display at least one of a frontal image of the tooth, an occlusal surface image of the tooth, and a lateral image of the tooth, and display the manipulator in each image.

[0076] In operation S430, which displays the manipulator, the digital tooth setting device can simultaneously display at least two of the following images: a frontal image of the tooth, an occlusal surface image of the tooth, and a lateral image of the tooth, and display the manipulator in each image. Then, in operation S440, which performs tooth setting using the manipulator, when the manipulator in the predetermined image is manipulated by the user, the digital tooth setting device can reflect the result of the manipulation in real time and display it on at least one other image.

[0077] In operation S430 of the display manipulator, the digital tooth setting device can display at least one of the extraction interface, the tooth fixation interface, and the proximal enamel removal interface.

[0078] There are situations where tooth extractions or proximal enamel removal are performed to ensure space when setting teeth for treatment, and there are also situations where remaining teeth are moved after teeth that will not be moved have been fixed. In these cases, the user interface for performing treatment techniques can be included and displayed in a manipulator for performing tooth fine-tuning. In this scenario, tooth fine-tuning and representative treatment techniques can be applied at the same step. Therefore, the continuity of work can be increased and the hassle of moving between pages can be reduced, thereby improving operator convenience.

[0079] According to the process of performing treatment technology functions using the manipulator of the present invention, in operation S420 of receiving a selection input for a tooth, the digital tooth setting device receives a selection input for the tooth requiring treatment technology through the user's operation. Then, in operation S430 of displaying the manipulator, a guide interface can be displayed around the selected tooth, and a manipulator including at least one of an extraction interface, a tooth fixation interface, and an interproximal enamel removal interface can be displayed near the guide interface. In operation S440 of performing tooth setting using the manipulator, the digital tooth setting device receives a selection input from the displayed manipulator for a predetermined treatment technology interface (e.g., extraction interface, tooth fixation interface, and interproximal enamel removal interface), performs the selected treatment technology function, and displays the result of the performance on the screen.

[0080] As a result of the process, in the case of tooth extraction, selected teeth can be deleted, and the portion where the selected teeth were deleted can be displayed as an empty space. Teeth can be arranged by moving or rotating them using the space created by the extraction. In the case of tooth fixation, when another interface, such as the tooth movement interface or tooth rotation interface, is operated on after the selected teeth have been fixed, the corresponding teeth do not move. In the case of interproximal enamel removal, the number of teeth entered by the user is deleted and displayed. Furthermore, even when performing interproximal enamel removal, teeth can be arranged by moving or rotating them in the space created by the deletion in the same manner as tooth extraction.

[0081] As described above, when using a manipulator to set up teeth, tooth fine-tuning and dental treatment techniques can be applied to the same screen, thus reducing the number of procedures. For example, on a single screen, the following procedures can be performed: move a tooth → confirm adjacent teeth → change adjacent teeth or perform proximal enamel removal.

[0082] Figure 3 This is a flowchart illustrating a method for fine-tuning teeth using a manipulator according to an embodiment of the present invention.

[0083] Reference Figure 3 The digital tooth setting device can display dental image data (S510) and receive selection input for the tooth requiring fine-tuning through user manipulation of the displayed dental image data (S520). Next, a tooth fine-tuning interface is displayed on a guide interface surrounding the selected tooth (S530). The tooth fine-tuning interface may include at least one of a tooth movement interface and a tooth rotation interface. Here, the guide interface is configured as a ring around the tooth, and the tooth fine-tuning interface is disposed on the ring.

[0084] Next, the digital teeth setting device performs teeth fine-tuning through the user's operation using the teeth fine-tuning interface (S540).

[0085] Next, the digital tooth setting device determines whether the selected tooth will collide with an adjacent tooth when making fine adjustments (S550), and compensates for the amount of movement of the adjacent tooth by reflecting the expected collision at the time of the collision (S560). For example, when a tooth is moved using a tooth movement interface through user manipulation, the digital tooth setting device can reflect the expected collision with an adjacent tooth and also perform the movement of the adjacent tooth. In this case, the expected collision with an adjacent tooth can be visualized and displayed.

[0086] Figures 4 to 7 It is a view used to describe an embodiment of the present invention, which displays a manipulator for tooth fine-tuning and a tooth movement interface and a tooth rotation interface used during tooth fine-tuning.

[0087] More specifically, Figure 4 This is a view showing the display screen of the manipulator on the front of the teeth. Figure 5 This is a view showing the display screen of the manipulators on the occlusal surface of the teeth. Figure 6 This is a view showing the display screen of the manipulator on the lateral surface of the tooth, and Figure 7 This is a view used to describe the tooth fine-tuning interface according to an embodiment of the present invention.

[0088] Reference Figures 4 to 7 When a user selects a predetermined single tooth 600, a guide interface 610 is displayed around the selected tooth 600. The guide interface 610 is an interface displayed on the screen to assist the user in manipulating tooth settings on dental image data. The guide interface 610 can be configured in the form of a ring formed around the position of the selected tooth 600. The ring can have a circular shape, but the invention is not limited thereto. The shape of the ring does not have to be a perfect circle around the selected tooth 600, and the ring can have any size, as long as the ring is positioned near the single tooth based on the selected tooth 600.

[0089] The tooth fine-tuning interface can be positioned on the guide interface 610. The tooth fine-tuning interface may include at least one of a tooth movement interface and a tooth rotation interface. The tooth movement interface is a user interface displayed on the screen for moving the selected tooth 600. The tooth movement interface may include mesial and distal movement interfaces (forward and backward movement) 1-d and 2-d, indentation and extrusion movement interfaces (up and down movement) 1-e and 2-e, and buccal and lingual movement interfaces (forward and narrowing movement) 1-f and 2-f.

[0090] The tooth rotation interface is a user interface displayed on the screen for rotating the selected tooth 600. The tooth rotation interface may include angle adjustment interfaces (left anterior and right anterior rotation) 1-a and 2-a, rotation adjustment interfaces (left occlusion and right occlusion rotation) 1-b and 2-b, and torque adjustment interfaces (front anterior and narrow rotation) 1-c and 2-c.

[0091] like Figures 4 to 6 As shown, the tooth movement interface and tooth rotation interface can be provided in the form of buttons with arrow directions, but the invention is not limited thereto. The tooth movement interface and tooth rotation interface can be positioned on a ring formed at a predetermined distance around the selected tooth 600.

[0092] When the mouse hovers over an interface with a function the user wants to use, recognizable color information can be used to categorize or highlight the corresponding interface. For example, users can visually check the function they want to use by filling it with color, changing the color to emphasize the background, or changing the line to be thicker and displaying the changed line.

[0093] The tooth fine-tuning interface can be divided into a collision compensation interface and a collision ignore interface based on the movement of adjacent teeth. Figure 7 In the diagram, collision compensation interfaces 1-a, 1-b, 1-c, 1-d, 1-e, and 1-f, and collision ignore interfaces 2-a, 2-b, 2-c, 2-d, 2-e, and 2-f, are described by dividing the interface into different types for tooth movement and tooth rotation. For example... Figures 4 to 6 As shown, the collision compensation interfaces 1-a, 1-b, 1-c, 1-d, 1-e, and 1-f, and the collision ignore interfaces 2-a, 2-b, 2-c, 2-d, 2-e, and 2-f, can be displayed by dividing them into recognizable visual information. For example, users can visually distinguish between the collision compensation interfaces 1-a, 1-b, 1-c, 1-d, 1-e, and 1-f and the collision ignore interfaces 2-a, 2-b, 2-c, 2-d, 2-e, and 2-f by filling them with color, changing the color to emphasize the background, or changing the lines to be thicker and displaying the changed lines.

[0094] Collision compensation interfaces 1-a, 1-b, 1-c, 1-d, 1-e, and 1-f, along with collision ignore interfaces 2-a, 2-b, 2-c, 2-d, 2-e, and 2-f, can be displayed symmetrically to each other relative to the center of the guide interface. For example, collision compensation interfaces 1-a, 1-b, 1-c, 1-d, 1-e, and 1-f, along with collision ignore interfaces 2-a, 2-b, 2-c, 2-d, 2-e, and 2-f, can be displayed on each of the upper right and lower left ends about the axis. Alternatively, collision compensation interfaces 1-a, 1-b, 1-c, 1-d, 1-e, and 1-f, along with collision ignore interfaces 2-a, 2-b, 2-c, 2-d, 2-e, and 2-f, can be displayed on each of the lower left and upper right ends about the axis. Alternatively, the collision compensation interfaces 1-a, 1-b, 1-c, 1-d, 1-e, and 1-f and the collision ignore interfaces 2-a, 2-b, 2-c, 2-d, 2-e, and 2-f can be displayed at positions that are horizontally symmetrical to each other or vertically symmetrical to each other.

[0095] exist Figure 7 Although both tooth movement and tooth rotation interfaces are displayed simultaneously, a user selection interface is provided that allows the user to choose between collision compensation interfaces 1-a, 1-b, 1-c, 1-d, 1-e, and 1-f or collision ignore interfaces 2-a, 2-b, 2-c, 2-d, 2-e, and 2-f. Depending on the user's selection, only collision compensation interfaces 1-a, 1-b, 1-c, 1-d, 1-e, and 1-f, or only collision ignore interfaces 2-a, 2-b, 2-c, 2-d, 2-e, and 2-f, can be displayed. In this case, since only the necessary interfaces are displayed on the screen, the user can be guided to make operation easier.

[0096] When the user selects collision compensation interfaces 1-a, 1-b, 1-c, 1-d, 1-e, and 1-f, the digital tooth setting device determines whether a collision occurs between the selected tooth 600 and its neighboring teeth. If a collision occurs, the collision direction and overlap amount can be calculated. In this case, whether a collision has occurred can be classified as identifiable visual information and displayed, and the calculation of the collision direction and overlap amount can be displayed as identifiable visual or digital information.

[0097] When a collision occurs, the digital tooth setting device can compensate for the movement of adjacent teeth along an arc in the same direction as the selected tooth, according to the amount of overlap, within the range of the collision between the selected tooth and adjacent teeth (e.g., left maxillary, right maxillary, left mandibular, or right mandibular). For example, when the maxillary right central incisor (the selected tooth) moves 3 mm to the right, the maxillary right central incisor overlaps with the maxillary left central incisor on the opposite side of the maxillary right central incisor, and the incisors, canines, premolars, and molars on the left side of the left maxilla that collided compensate for a certain amount of collision, causing all teeth to move 3 mm to the right.

[0098] The corresponding function is a technology used to compensate for the shortcomings of the manipulator, which requires the user to individually correct adjacent teeth that collide when making fine adjustments to a single tooth using the manipulator.

[0099] at the same time, Figure 7 Interface configuration and Figures 4 to 6 The interface configurations and their respective positions included are examples used to describe the invention, but are not limited thereto, and the configuration and position of the manipulators can vary depending on the user's viewing angle. For example, when the user adjusts the viewing angle, the configuration of the manipulators can be changed to suit fine-tuning at the corresponding angle.

[0104] Reference Figure 9The system can display the positions of rotation center point candidates, around which rotational movements are performed to rotate the selected tooth using a manipulator, and a predetermined rotation center point can be selected from the rotation center point candidates through user manipulation. Alternatively, a basic center point can be preset and suggested among the rotation center point candidates, and the basic center point can be changed to another rotation center point through user manipulation. Rotation center point candidates for a tooth can be determined using tooth axis information with the selected individual tooth. In this case, the rotation center point candidates for a tooth can be displayed as multiple points along the long axis of the tooth. For example, the rotation center point candidates for a tooth include root apex 1101, root center 1102, root 1 / 3 point 1103, gingival margin 1104, tooth center 1105, cusp 1106, etc. By supporting multiple rotation center point candidates for a tooth, various rotational aspects of the tooth are possible. Figure 9 As shown in (a), candidates for the rotation center points of teeth can be displayed, and the basic center point 1103 among the candidates for the rotation center points can be presented, and as... Figure 9 As shown in (b), the user can change the rotation center point of the tooth to the tooth center 1105.
