Description

Technical Field

[0001] The present invention relates to a risk factor guidance method, and more particularly, to a device and method for guiding implant structure conflict risk factors during the process of formulating an implant placement plan. Background Art

[0002] Devices that use software to plan implant placement will automatically determine the position and orientation of the implant structure based on AI or algorithms and provide recommendations to the user. The user can make fine adjustments as needed, or the user can determine the position and orientation of the implant from the beginning.

[0003] However, when the user manually determines the implant position of the implant structure or fine-tunes the implant structure implantation suggestion, a conflict may occur between the implant structure and the patient's anatomy.

[0004] Therefore, a method is needed that can guide users to easily identify the relationship between risk factors and implant structures to avoid conflicts between implant structures and patient anatomy. Summary of the Invention

In the process of describing the example embodiments, when it is determined that the detailed description of the relevant well-known structures or functions will cause unnecessary confusion to the present disclosure, the detailed description thereof will be omitted.

[0042] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0043] Figure 1 FIG. 1 is a diagram of a computing device for executing a risk factor guidance method according to an embodiment of the present invention.

[0044] like Figure 1 As shown, the computing device 100 may include at least one processor 110 , a memory 130 for loading a program 140 executed by the processor 110 , and a storage space 120 for storing the program 140 . Figure 1 The components included in the computing device 100 are merely examples, and it is obvious to those skilled in the art that the computing device 100 may include components other than Figure 1 Other common components beyond those shown in .

[0045] The processor 110 controls the overall operation of each component of the computing device 100. The processor 110 can be at least one of a central processing unit (CPU), a microprocessor unit (MPU), a microcontroller unit (MCU), a graphics processing unit (GPU), or any other type of processor known in the art. In addition, the processor 110 can operate at least one application or program to perform methods / operations according to various embodiments of the present invention. The computing device 100 may include at least one processor.

[0046] The memory 130 stores various data, commands, and / or information. The memory 130 can load the program 140 stored in the storage space 120 to execute the methods / operations according to different embodiments of the present invention. An example of the memory 130 may be a random access memory (RAM), but the embodiment is not limited thereto.

[0047] The storage space 120 can non-temporarily store one or more programs 140. The storage space 120 can include non-volatile memories such as read-only memory (ROM), erasable programmable ROM (EPROM), electrically erasable programmable ROM (EEPROM), and flash memory; a hard disk drive (HDD); a solid-state disk (SSD); a removable disk; or any other form of computer-readable recording medium known in the art to which the present invention pertains.

[0048] Program 140 may include at least one action that implements a method / action according to various embodiments of the present invention. Here, an action corresponds to an instruction implemented in program 140. For example, program 140 may include the following actions: displaying a patient's dental image; displaying a screen after the dental image displays an implant structure; and, when a conflict is identified between the implant structure and the anatomical structure of the dental image, displaying an additional screen that displays images of the conflict risk factor from multiple different directions. For example, the dental image may include a CT image of the patient and an image of a dental model.

[0049] When the program 140 is loaded into the memory 120 , the processor 110 may perform methods / actions according to various embodiments of the present invention by executing a plurality of actions for implementing the program.

[0050] The execution screen of the program 140 can be displayed on the display 150. Figure 1 In the present invention, display 150 is a separate device connected to computing device 100. In computing device 100, such as a user-portable terminal such as a smartphone or tablet computer, display 150 may be a component of computing device 100. The screen displayed on display 150 may be a screen before information is input into a program, or may be the result of executing a program.

[0051] Specifically, the processor 110 of the computing device 100 may display a dental image of the patient on the display 150. For example, the dental image may be one of a CT image generated by photographing a region including the patient's upper jaw, lower jaw, and teeth, and a three-dimensional image generated by interpreting the CT image.

[0052] In addition, the processor 110 distinguishes anatomical structures such as teeth, neural canals, and maxillary sinuses in the dental image as separate objects, and applies different display effects or displays them in different colors, so that users can easily distinguish the anatomical structures.

[0053] Next, the processor 110 may display a screen after the implant structure is implanted on the dental image. At this time, the screen after the implant structure is implanted on the dental image may display the distance between the implant structure and the anatomical structure, and whether there is a conflict between the implant structure and the anatomical structure.

[0054] Next, the processor 110 can identify whether there is a conflict between the implant structure implanted in the dental image and the anatomical structure contained in the dental image. At this time, the processor 110 sets a safety distance for the implant structure in consideration of errors during the implant surgery. And, when it is determined that the anatomical structure is within the set implant structure safety distance, the processor 110 identifies that the implant structure conflicts with the anatomical structure.

[0055] If no conflict occurs between the implant structure and the anatomical structure, the processor 110 can determine an implant surgery plan to perform the surgery based on the implant's position and specifications as shown in the dental image. However, if a conflict occurs between the implant structure and the anatomical structure, the processor 110 can display an additional screen showing images of the conflict risk factor from multiple different angles. In this case, the processor 110 can issue a warning to inform the user of the conflict between the implant structure and the anatomical structure.

[0056] Furthermore, different additional views can be determined depending on the structure that conflicts with the implant structure.

[0057] For example, when it is identified that the implant structure conflicts with the inferior alveolar nerve canal in the anatomical structure, the processor 110 displays an additional screen and the length of the conflict area between the implant structure and the inferior alveolar nerve canal, wherein the additional screen displays images of the area where the implant structure and the inferior alveolar nerve canal are located from the buccal, lingual, mesial and distal directions.

[0058] In addition, when it is identified that the implant structure conflicts with the maxillary sinus in the anatomical structure, the processor 110 displays an additional screen, as well as the maxillary sinus object and the bone transplant area, wherein the additional screen displays images of the implant structure and the area where the maxillary sinus is located observed from the buccal, lingual, mesial and distal directions.

[0059] In addition, when it is identified that the implant structure conflicts with the adjacent tooth of a single tooth adjacent to the implant structure in the anatomical structure, the processor 110 displays an additional screen and the length of the conflict area between the implant structure and the adjacent tooth, wherein the additional screen displays images of the area where the implant structure and the single tooth are located observed from the buccal direction and the lingual direction.

[0060] In addition, the processor 110 may provide the user with a user interface for selecting an additional area on the screen. When the user selects an area using the user interface, the processor 110 displays a 2D image that is an enlarged 2D cross-sectional image of the user-selected area and a 3D image reconstructed for the user-selected area.

[0061] Next, the processor 110 displays the implant structure whose specifications are changed to prevent the implant structure from interfering with the anatomical structure.

[0062] According to one embodiment of the present invention, when formulating an implant placement plan in an implant surgery, when a conflict is identified from a patient's dental image between the implant structure to be implanted and the anatomical structure contained in the dental image, not only will a notification of the conflict be provided, but an additional screen will also be provided that displays the conflict risk factors from multiple directions, thereby guiding the user to easily identify the relationship between the risk factors and the implant structure.

[0063] Furthermore, according to an embodiment of the present invention, by guiding the user to easily identify the relationship between risk factors and implant structures, the user is assisted in accurately designing the position, angle, and specifications of the implant structure to prevent conflicts when implanting the implant.

[0064] Figure 2 This is an example of a screen for segmenting the anatomical structure of CT data according to an embodiment of the present invention.

[0065] The processor 110 can segment the patient's CT image 210 and separate each anatomical structure contained in the CT image 210, such as the inferior alveolar nerve 220, the maxillary sinus 230, and a single tooth, into a single object for loading. In addition, the processor 110 can use the segmented CT image 210 to provide the user with a tooth image including a 3D image and a 2D cross-sectional image. Figure 2 As shown, the processor 110 may display each anatomical structure, such as the inferior alveolar nerve 220 , the maxillary sinus 230 , and a single tooth, in a different color to enable the user to easily identify each anatomical structure.

[0066] Figure 3 This is an example of a process for setting a security zone according to an embodiment of the present invention.

[0067] The processor 110 may provide a screen 310 for setting a safe distance of the implant structure 311 in consideration of errors during the implant surgery. Figure 3 As shown, the processor 110 can set 1.5 mm in the horizontal direction and 2.0 mm downward as the safety distance.

[0068] Next, the processor 110 may define an area 322 located within a preset safety distance from the implant structure 311 as a safety zone 320. In this case, the safety zone 320 may be used to identify conflicts between the implant structure and the anatomical structure. Specifically, when the anatomical structure approaches the safety zone 320, the processor 110 may identify a conflict between the implant structure and the anatomical structure, even if the implant structure and the anatomical structure are not in contact or the predetermined areas of the implant structure and the anatomical structure do not overlap.

[0069] Figure 4 This is an example of an additional screen displayed when the implant structure conflicts with the inferior alveolar nerve canal during the implant placement process in a patient's mandible.

[0070] The processor 110 can display the image 410 after the implant structure 411 is implanted in the dental image. Figure 4 As shown, the dental image may include a 2D cross-sectional image displayed on the right side of the screen and a 3D image displayed on the left side of the screen.

[0071] Specifically, the multiple 2D cross-sectional images shown on the right can be cross-sectional images with different axes, respectively, and can display an axial axis (AA) cross-sectional image of the horizontal plane of the maxillary or mandibular, a mesial-distal axis (MA) cross-sectional image of the cross-sectional section perpendicular to the dental arch line generated in the AA cross-sectional image, a buccal-lingual axis (BA) cross-sectional image of the cross-sectional section parallel to the dental arch line, and a panoramic image.

[0072] Furthermore, the processor 110 can identify whether there is a conflict between the implant structure 411 and an anatomical structure such as the inferior alveolar nerve canal 412. When a conflict occurs between the implant structure 411 and the inferior alveolar nerve canal 412, the processor 110 can display a screen 420. Furthermore, even if there is no conflict between the implant structure and the inferior alveolar nerve canal, the processor 110 can display the screen 420 based on a user's selection, allowing the user to confirm the distance between the implant structure and the inferior alveolar nerve canal.

[0073] The processor 110 may display a screen 420 in which the color of the implant structure 411 is changed from a default color to a color 421 indicating that a conflict has occurred.

[0074] However, if only the presence of a conflict is indicated, it may be difficult for the user to identify the positional relationship between the inferior alveolar nerve canal 412 and the implant structure 411, which are risk factors for conflict. This makes it difficult for the user to determine an implant angle or position that avoids the conflict without changing the length of the implant structure 411. Therefore, the processor 110 may display at least one additional screen that only includes risk factors such as the inferior alveolar nerve canal 412 and the implant structure 411, allowing the user to easily identify the positional relationship between the risk factors such as the inferior alveolar nerve canal 412 and the implant structure 411.

[0075] At this time, the processor 110 can guide the user to easily identify the relationship between risk factors and the implant structure by displaying an additional screen 423 of the image of the implant structure and the area where the inferior alveolar nerve canal is located observed from the buccal direction, an additional screen 425 of the image of the implant structure and the area where the inferior alveolar nerve canal is located observed from the lingual direction, an additional screen of the image of the implant structure and the area where the inferior alveolar nerve canal is located observed from the mesial direction, and an additional screen of the image of the implant structure and the area where the inferior alveolar nerve canal is located observed from the distal direction.

[0076] Additionally, the processor 110 may display a length 422 of the conflicting region between the implant structure and the inferior alveolar nerve canal. In this case, the conflicting region length 422 may be a numerical value representing the length of the region where the implant's reference axis conflicts with the inferior alveolar nerve canal 412. Furthermore, the additional screen displays a three-dimensional image, and each image displayed on the additional screen can be freely rotated based on user input for confirmation from all three-dimensional directions.

[0077] During the implant structure adjustment process, if a risk factor conflicts with the implant structure, an implant adjustment interface will be displayed to enlarge the area where the user can adjust the implant structure. At this time, the position of the implant adjustment interface operated by the user on the screen changes, which may cause inconvenience to the user. For example, the implant adjustment interface displays a window to receive input for at least one of the implant structure size, position, and angle, and can adjust at least one of the implant structure size, position, and angle based on the value entered into the display window. In addition, the implant adjustment interface displays + and - icons for the user to change at least one of the implant structure size, position, and angle. When the user selects an icon, the size, position, or angle of the implant structure corresponding to the icon can be enlarged or reduced.

[0078] Therefore, the processor 110 maintains the area where the user can adjust the implant structure, and provides additional images in other areas for the user to refer to when adjusting the implant structure, so that the user can easily adjust the implant structure.

[0079] Figure 5 FIG. 4 is an example of a process for implanting an implant structure according to an embodiment of the present invention.

[0080] like Figure 5 As shown, the processor 110 can receive the user's preferred implant setting information 510 and the tooth number information 520 of the implant to be implanted. In addition, the processor 110 can automatically determine the position of the implant structure 531 by considering the input information and the anatomical structure contained in the tooth image 530.

[0081] Figure 6 This is an example of a process for changing the structural specifications of an implant according to an embodiment of the present invention.

[0082] After the processor 110 implants the implant structure 611 according to the implant setting information preferred by the user, the processor 110 can identify whether there is a conflict between the implant structure 611 and the inferior alveolar nerve canal 612. When the implant structure 611 conflicts 610 with the inferior alveolar nerve canal 612, the processor 110 can implant an implant structure 613 with changed specifications to prevent the conflict and display 620 it to the user. Figure 6 As shown, the vertical length of the implant structure 613 may be smaller than that of the implant structure 611 .

[0083] However, when the specifications of the implant structure 613 are changed to avoid conflict with the inferior alveolar nerve canal 612, there may be a difference between the specifications expected by the user. Therefore, the processor 110 may display the implant structure 613 and an implant adjustment interface for adjusting the implant structure 613 in an area where the user can adjust the implant structure, and display additional screens in other areas.

[0084] Figure 7 This is an example of an additional screen displayed when the implant structure 710 conflicts with the maxillary sinus during the implantation of the implant structure in the patient's maxilla.

[0085] At this point, the processor 110 may display a translucent maxillary sinus object 720 representing the patient's maxillary sinus. Furthermore, the processor 110 may display a spherical region 721 in a different color from other areas of the maxillary sinus in the area where the maxillary sinus and the implant structure 710 collide, for user confirmation. Here, the spherical region 721 corresponds to the distance of the bone graft region set relative to the implant reference axis.

[0086] And, as Figure 7As shown on the left screen, the processor 110 can display images of the implant structure 710 and the area surrounding the maxillary sinus from the buccal, lingual, mesial, and distal directions. The additional screen 730 displays a three-dimensional image, and each image displayed on the additional screen can be freely rotated based on user input for confirmation from all three directions.

[0087] In addition, the processor 110 can use numerical values to represent the length of the conflicting area and the volume of the bone graft area based on the implant structure 710 and the maxillary sinus, with the implant reference axis as a reference. For example, the processor 110 can use numerical values to represent the volume of the area requiring bone grafting and the amount of bone grafting.

[0088] Figure 8 8 is an example of an additional screen displayed when an implant structure 810 collides with a neighboring tooth 820 , which is a single tooth adjacent to the implant structure in an anatomical structure, according to an embodiment of the present invention.

[0089] At this time, the processor 110 can display an additional screen showing an image of the area where the implant structure 810 and the adjacent teeth 820 are located, viewed from the buccal direction, and an additional screen 830 showing an image of the area where the implant structure 810 and the adjacent teeth 820 are located, viewed from the lingual direction. In this case, the additional screen 830 is displayed as a three-dimensional image, and each image displayed on the additional screen can be freely rotated according to user input to confirm from all three-dimensional directions.

[0090] In addition, the processor 110 may display the adjacent teeth 820 in a semi-transparent form, so that the user can easily confirm the area where the implant structure 810 and the adjacent teeth 820 conflict.

[0091] In addition, if Figure 8 As shown, the processor 110 may display the length of the region where the implant structure 810 conflicts with the adjacent tooth 820 as the length of the conflict region of the adjacent tooth (0.83 mm).

[0092] Figure 9 This is an example of an additional screen that appears when a conflict occurs between implant structures while multiple implant structures are being implanted in an area with consecutive tooth numbers.

[0093] At this time, the processor 110 may display an additional screen showing an image of the area where the implant structure is located from the buccal direction, and an additional screen 930 showing an image of the area where the implant structure is located from the lingual direction. In this case, the additional screen 930 is displayed as a three-dimensional image, and each image displayed on the additional screen can be freely rotated based on user input to confirm from all three-dimensional directions.

[0094] In addition to displaying the implant structure, the processor 110 may also display adjacent teeth adjacent to the implant structure. When there are adjacent teeth on both sides of the implant structure, the processor 110 may display the adjacent tooth closest to the implant structure, or display all adjacent teeth on both sides of the implant structure.

[0095] In addition, the processor 110 can display the implant structure 910 being adjusted using the implant adjustment interface as opaque, and display the implant structure 920 that is passively conflicted due to the adjustment of the implant structure 910 as semi-transparent, so that the user can easily confirm the conflict area of the implant structure 920 that is conflicted by the implant structure 910.

[0096] And, as Figure 9 As shown, the processor 110 may display the length (0.81 mm) of the conflicting region of the implant structure 920 that is conflicted by the implant structure 910 .

[0097] In addition, despite Figure 9 The conflict between implant structures is shown. When an object used for surgical planning, such as an anchor pin for guidance and fixation, conflicts with the implant structure 910 , the object may be displayed in the same manner as the implant structure 920 .

[0098] Figure 10 This is an example of an additional screen displayed when the implant structure exceeds the alveolar bone safety zone according to an embodiment of the present invention.

[0099] If the patient has sufficient bone volume, the implant structure 1010 can be stably implanted and positioned in the alveolar bone, and when planning the implant implantation range in the alveolar bone, the patient's alveolar bone can be included in the implant safety zone.

[0100] However, if the safety distance in the buccal and lingual directions of the implant structure 1010 is set within 1.5 mm, and there is no alveolar bone more than 1.5 mm in the buccal and lingual directions of the top surface of the implant, problems may occur during the operation.

[0101] Therefore, if Figure 10As shown, the processor 110 can display an additional screen showing an image of the implant structure 1010 and the patient's alveolar bone from the mesial direction, and an additional screen 1030 showing an image of the implant structure 1010 and the patient's alveolar bone from the distal direction. In this case, the additional screen 1030 is displayed as a three-dimensional image, and each image displayed on the additional screen can be freely rotated based on user input to confirm from all three-dimensional directions. Furthermore, the processor 110 can display a warning to the user.

[0102] In addition, the processor 110 can display the patient's alveolar bone as semi-transparent and the implant structure 1010 as opaque, thereby visually displaying the implant structure 1010 located within the alveolar bone. Furthermore, for areas where the alveolar bone thickness is less than 1.5 mm, the processor can represent the area using a value that deviates from the edge of the alveolar bone safety zone.

[0103] Figure 11 is an example of an enlarged screen according to an embodiment of the present invention.

[0104] The processor 110 may provide a screen 1110 including a user interface 1111 that allows a user to select an area in the additional screen. Figure 11 As shown, for example, user interface 1111 may be displayed as a square border. Furthermore, user interface 1111 may receive a user's move request via one of a preset shortcut key, a keyboard arrow key, mouse movement, or an icon for selecting a movement direction, and move the rectangular border in accordance with the move request. If the user's move request is not received within a certain period of time, or a request to complete the move is received from the user, user interface 1111 may determine the area contained within the rectangular border at that time as the user-selected area.

[0105] Furthermore, when a user selects an area through user interface 1111, processor 110 may display screen 1120, which includes 2D image 1121, which is a magnified 2D cross-sectional image of the user-selected area, and 3D image 1123, which is a reconstructed magnified image of the user-selected area. At this point, the selected area can be changed or the magnification ratio can be adjusted in 2D image 1121 or 3D image 1123 through user interface 1111, and 2D image 1121 and 3D image 1123 can reflect changes in the selected area in real time.

[0106] In addition, the size of the implant adjustment interface can match the 2D image 1121 so that the user can operate it in the 2D image 1121 .

[0107] Figure 12 is a flow chart of a risk factor guidance method according to an embodiment of the present invention.

[0108] In step 1210, the processor 110 may display a dental image of the patient on the display 150. At this point, the processor 110 may separate anatomical structures such as the teeth, neural canal, and maxillary sinus in the dental image into separate objects, and apply different display effects or display them in different colors, so that the user can easily distinguish between the anatomical structures.

[0109] In step 1220 , the processor 110 may display the image after the implant structure is implanted on the dental image.

[0110] In step 1230 , the processor 110 may identify whether there is a conflict between the implant structure implanted in the dental image and the anatomical structure contained in the dental image.

[0111] When there is no conflict between the implant structure and the anatomical structure, the processor 110 can determine an implant surgery plan to perform the implant surgery according to the position and specifications of the implant structure implanted in the dental image. In addition, when there is a conflict between the implant structure and the anatomical structure, the processor 110 can execute step 1240.

[0112] In step 1240, the processor 110 may display additional images of the conflict risk factor from multiple different directions. In this case, the processor 110 may issue a warning to the user, informing them that a conflict has occurred between the implant structure and the anatomical structure. Furthermore, different additional images may be determined based on the structure that conflicts with the implant structure.

[0113] In step 1250 , the processor 110 may display the implant structure with specifications changed to prevent the implant structure from interfering with the anatomical structure.

[0114] In this case, step 1250 may be skipped depending on the embodiment, or may be performed before step 1240. When step 1250 is performed before step 1240, in step 1240, the processor 110 may provide an implant adjustment interface for fine-tuning the implant structure whose specifications have been changed in step 1250, and may display additional screens for reference when fine-tuning the implant structure whose specifications have been changed.

[0115] When formulating an implant placement plan in an implant surgery, the present invention not only notifies the user of the conflict when a conflict is detected between the implant structure to be implanted and the anatomical structure contained in the dental image, but also provides an additional screen showing the conflict risk factors from multiple directions, thereby guiding the user to easily identify the relationship between the risk factors and the implant structure.

[0116] Furthermore, the present invention assists users in accurately designing the position, angle, and specifications of the implant structure to prevent conflicts when implanting the implant by guiding the user to easily identify the relationship between risk factors and the implant structure.

[0117] Meanwhile, the risk factor guidance method of the present invention can be written as a program executable on a computer and can be implemented as various recording media such as a magnetic storage medium, an optical reading medium, and a digital storage medium.
