Description

Method for designing a guide template for implant surgery, computing device for performing the method, and computer-readable recording medium therefor

[0001] The present invention relates to a method for designing a guide template for implant surgery using software and a computing device for performing the method.

[0002] Software for designing guide templates for implant surgery can design guide templates that include drilling holes after implanting a virtual implant by aligning computed tomography (CT) data and oral scan data.

[0003] The user can perform implant surgery by attaching the guide template to the patient's oral cavity and then using a guide drill in the drilling hole formed in the guide template.

[0004] When a guide drill is used in a drilling hole formed in the guide template after the guide template is attached to the patient's mouth, the guide template may be broken if the drilling hole is located near an adjacent tooth or window, or due to rough drilling by the user.

[0005] Fracture of such guide templates can not only cause errors in the pre-planned implant position during implant placement, but also pose risks during implant surgery.

[0006] The present invention aims to provide a method and device for designing a guide template for implant surgery using software.

[0007] The present invention seeks to provide a method and device for designing a guide template based on the durability of the guide template for implant surgery.

[0008] A guide template design method according to one embodiment of the present invention may include the steps of: implanting a virtual implant on registration data obtained by matching CT data and oral scan data; generating a guide template including at least one of a drilling hole, a window, and a reinforcing bar corresponding to the virtual implant on the oral scan data of the registration data; activating a color map for indicating durability of the guide template based on a thickness of the guide template; and providing a user interface capable of changing the thickness of the guide template with respect to a durability risk area identified through the activated color map.

[0009] The thickness of the above guide template can be determined in at least one of the areas from the outer line of the drilling hole to the surface of at least one adjacent tooth adjacent to the drilling hole and the areas from the outer line of the drilling hole to the outer line of at least one window adjacent to the drilling hole.

[0010] The step of activating the above color map can activate a color map to indicate the durability of the guide template through a gradation technique in which colors continuously change according to the thickness of the guide template.

[0011] The step of activating the above color map may display a separate instruction line to indicate the area with the thinnest thickness of the above guide template.

[0012] The step of activating the above color map can display the measurement value for the area with the thinnest thickness of the above guide template in conjunction with the above instruction line.

[0013] The step of activating the above color map may provide a separate warning indicator indicating the durability risk area when the thickness of the above guide template is below a preset value.

[0014] The user interface may include at least one of a first item for changing the implantation position of a virtual implant implanted on the alignment data, a second item for deleting the closest adjacent tooth of the drilling hole, a third item for adding a reinforcing bar of the guide template, a fourth item for deleting a window of the guide template, and a fifth item for changing the type of a 3D printer that generates the guide template and a printing material of the guide template.

[0015] According to one embodiment of the present invention, a computing device includes one or more processors; and a memory for loading or storing a program executed by the processor, wherein the program may include an operation of implanting a virtual implant on registered data obtained by registering CT data and oral scan data, an operation of generating a guide template including at least one of a drilling hole, a window, and a reinforcing bar corresponding to the virtual implant on oral scan data of the registered data, an operation of activating a color map for indicating durability of the guide template based on a thickness of the guide template, and an operation of providing a user interface capable of changing the thickness of the guide template with respect to a durability risk area identified through the activated color map.

[0016] The thickness of the above guide template can be determined in at least one of the areas from the outer line of the drilling hole to the surface of at least one adjacent tooth adjacent to the drilling hole and the areas from the outer line of the drilling hole to the outer line of at least one window adjacent to the drilling hole.

[0017] The above processor can activate a color map to indicate the durability of the guide template through a gradation technique in which the color continuously changes according to the thickness of the guide template.

[0018] The above processor may display a separate instruction line to indicate the area of ​​the guide template with the thinnest thickness in the activated color map.

[0019] The above processor can display the measurement value for the area with the thinnest thickness of the guide template in the activated color map in conjunction with the instruction line.

[0020] The above processor may provide a separate warning indicator indicating the durability risk area when the thickness of the above guide template is below a preset value.

[0021] The user interface may include at least one of a first item for changing the implantation position of a virtual implant implanted on the alignment data, a second item for deleting the closest adjacent tooth of the drilling hole, a third item for adding a reinforcing bar of the guide template, a fourth item for deleting a window of the guide template, and a fifth item for changing the type of a 3D printer that generates the guide template and a printing material of the guide template.

[0022] According to one embodiment of the present invention, by activating a color map when designing a guide template for implant surgery, the durability of the guide template can be visually confirmed.

[0023] According to one embodiment of the present invention, a user interface for preventing breakage of a guide template during implant surgery can be provided based on the durability of the guide template visually confirmed through a color map.

[0031] Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings.

[0032] FIG. 1 is a diagram showing the configuration of a computing device according to one embodiment of the present invention.

[0033] As illustrated in FIG. 1, a computing device (100) may include one or more processors (110) and a memory (120) for loading or storing a program (130) executed by the processors (110). The components included in the computing device (100) of FIG. 1 are merely examples, and a person skilled in the art to which the present invention pertains will recognize that other general components may be included in addition to the components illustrated in FIG. 1.

[0034] The processor (110) controls the overall operation of each component of the computing device (100). The processor (110) may be configured to include at least one of a CPU (Central Processing Unit), an MPU (Micro Processor Unit), an MCU (Micro Controller Unit), a GPU (Graphics Processing Unit), an NPU (Neural Processing Unit), a DSP (Digital Signal Processor), or any other type of processor well known in the art of the present invention. In addition, the processor (110) may perform operations for at least one application or program for executing methods / operations according to various embodiments of the present invention. The computing device (100) may include one or more processors.

[0035] The memory (120) stores one or more combinations of various data, instructions, and information used by components (e.g., processor (110)) included in the computing device (100). The memory (120) may include volatile memory and / or non-volatile memory.

[0036] The program (130) may include one or more actions in which methods / operations according to various embodiments of the present invention are implemented, and may be stored in the memory (120) in the form of software. Here, the actions correspond to commands realized in the program (130). For example, the program (130) may include instructions for performing an action of implanting a virtual implant on the registration data obtained by matching CT data and oral scan data, an action of generating a guide template including a drilling hole, a window, and a reinforcing bar corresponding to the virtual implant on the oral scan data of the registration data, an action of activating a color map for indicating the durability of the guide template based on the thickness of the guide template, and an action of providing a user interface for changing the thickness of the guide template for a durability risk area identified through the activated color map.

[0037] When the program (130) is loaded into the memory (120), the processor (110) can perform methods / operations according to various embodiments of the present invention by executing a plurality of operations to implement the program (130).

[0038] The execution screen of the program (130) can be displayed through the display (140). In the case of FIG. 1, the display (140) is represented as a separate device connected to the computing device (100). However, in the case of a computing device (100) such as a terminal that a user can carry, such as a smartphone or tablet, the display (140) can be a component of the computing device (100). The screen displayed on the display (140) can be before inputting information into the program or the result of executing the program.

[0039]

[0040] FIG. 2 is a flowchart illustrating a guide template design method according to one embodiment of the present invention.

[0041] The guide template design method illustrated in FIG. 2 is performed by the processor (110) of the computing device (100) illustrated in FIG. 1. Referring to FIG. 2, in step (210), the processor (110) can implant a virtual implant on the aligned data obtained by matching CT data and oral scan data.

[0042] First, the processor (110) can align the patient's CT data and oral scan data using implant surgery guide template design software to output aligned data. The processor (110) can select a virtual implant corresponding to the tooth number requiring implant placement from an implant library and display it at the placement location on the aligned data. At this time, the virtual implant can be selected from different implant libraries for each manufacturer and can have different diameters and lengths corresponding to the tooth number.

[0043] The virtual implant may have its implantation position determined manually by the user, or automatically by a separate implant implantation position determination algorithm. The processor (110) may, if necessary, fine-tune the implantation position of the virtual implant by moving or rotating the virtual implant according to a user command, for which the implantation position has been determined manually or automatically.

[0044] In step (220), the processor (110) can generate a guide template corresponding to the virtual implant on the oral scan data of the matching data. First, the processor (110) can identify a guide template line by connecting points selected by the user on the patient's oral scan data, and generate a guide template using the identified guide template line.

[0045] Alternatively, the processor (110) can generate a guide template using guide template lines automatically identified by an algorithm for determining the shape of the guide template. In this case, the processor (110) can quickly generate a more sophisticated guide template by modifying the identified guide template lines according to user commands, if necessary.

[0046] At this time, the guide template can form a drilling hole for drilling during implant surgery. The location and size of such a drilling hole can be manually determined by the user, or the location and size can be automatically determined based on a virtual implant using a separate drilling hole formation algorithm. If the drilling hole is formed automatically, the processor (110) can adjust the location and size of the drilling hole according to user commands, if necessary.

[0047] Additionally, the guide template may be configured with a window to confirm the patient's oral cavity. The position, size, and thickness of this window may be manually determined by the user, or automatically determined by a separate window formation algorithm. If the window is automatically formed, the processor (110) may adjust the position, size, and thickness of the window according to user commands, if necessary.

[0048] Additionally, the guide template can be configured to form reinforcement bars for areas at risk of durability, such as drilling holes, windows, or the patient's oral condition. The position, size, and thickness of these reinforcement bars can be manually determined by the user, or automatically determined by a separate reinforcement bar formation algorithm. If the reinforcement bars are formed automatically, the processor (110) can adjust the position, size, and thickness of the reinforcement bars according to user commands, if necessary.

[0049] In step (230), the processor (110) may activate a color map to indicate the durability of the guide template based on the thickness of the generated guide template. As an example, FIG. 3 illustrates an example of a guide template (310) formed with a drilling hole, a window, and a reinforcing bar corresponding to a virtual implant according to an embodiment of the present invention, displayed on a display.

[0050] When the color map activation button (320) displayed on the display together with the guide template (310) is clicked, the processor (110) can activate a color map (410) to indicate the durability of the guide template through a gradation technique in which the color continuously changes according to the thickness of the guide template, as shown in FIG. 4.

[0051] At this time, the thickness of the guide template can be determined in at least one of the areas from the outer line of the drilling hole to at least one adjacent tooth surface adjacent to the drilling hole and the areas from the outer line of the drilling hole to at least one window outer line adjacent to the drilling hole.

[0052] Therefore, when there are multiple adjacent teeth or windows adjacent to a drilling hole, the processor (110) can check the thickness of the guide template for each of the multiple areas and display it as a color map.

[0053] For example, a color map (410) regarding the durability of a guide template can be expressed by a color map bar (420) displayed in a gradient of green (#18BC4D) when the thickness of the guide template is about 3 mm or more, blue (#72B8CC) when it is about 3 mm or less and about 2.5 mm or more, purple (#BAB9E6) when it is about 2.5 mm or less and about 1.5 mm or more, and red (#E64251) when it is about 1.5 mm or less. At this time, the symbol in parentheses indicates the color hex value.

[0054] Meanwhile, when the color map (410) is activated for the guide template, the processor (110) can display the area with the thinnest thickness of the guide template through a separate instruction line (430) so that the user can intuitively check it.

[0055] In addition, the processor (110) can automatically measure the thickness of the guide template at the same time as the color map (410) is activated for the guide template. At this time, the processor (110) can display the measurement value for the area with the thinnest thickness of the guide template as a specific numerical value in conjunction with the indication line (430), thereby providing the user with more accurate information regarding the thickness of the guide template.

[0056] If the thickness of the guide template is less than a preset value, the processor (110) may provide a separate warning indicator (440) indicating a durability risk area of ​​the guide template. For example, referring to FIG. 4, if a durability risk area exists where the thickness of the guide template is less than or equal to 1.5 mm, the processor (110) may provide a warning indicator (440) such as an exclamation mark for the area so that the user can more quickly and intuitively recognize the durability risk area.

[0057] If there are multiple durability risk areas where the guide template has a thickness of 1.5 mm or less, the processor (110) can provide a warning indicator (440) and measurement values ​​only for the durability risk area with the thinnest thickness for each drilling hole by tooth number.

[0058] At step (240), the processor (110) may provide a user interface that can change the thickness of the guide template for a durability risk area identified through an activated color map.

[0059] More specifically, when a warning indicator (510) for a durability risk area of ​​a guide template is selected as shown in FIG. 5, a user interface (520) that can change the thickness of the guide template can be provided on the screen or activated in a pop-up form.

[0060] At this time, the user interface (520) may include at least one item among a first item (521) for changing the implantation position of a virtual implant implanted on the matching data, a second item (522) for deleting the closest adjacent tooth of a drilling hole, a third item (523) for adding a reinforcing bar of a guide template, a fourth item (524) for deleting a window of a guide template, and a fifth item (525) for changing the type of 3D printer that generates the guide template and the printing material of the guide template.

[0061] At this time, when one of the multiple items is selected, the user interface (520) may activate the Apply button (Apply) that is in an inactive state.

[0062] If the first item (521) for changing the implantation position of a virtual implant implanted on the matching data is selected, the processor (110) can enter a step (210) for implanting a virtual implant so that the user can change the implantation position for the virtual implant.

[0063] Additionally, if the second item (522) for deleting the closest adjacent tooth of the drilling hole is selected, the processor (110) may enter a tooth deletion step to enable the user to delete the adjacent tooth from the patient's oral scan data.

[0064] Additionally, if the third item (523) for adding a reinforcement bar to the guide template and the fourth item (524) for deleting a window of the guide template are selected, the processor (110) may proceed to the step (220) of generating a guide template so that the user can add a reinforcement bar or delete a window.

[0065] Finally, if the fifth item (525) for changing the type of 3D printer that creates the guide template and the printing material of the guide template is selected, the processor (110) can enter a user setting screen such as FIG. 6 so that the user can change the type of 3D printer or the printing material.

[0066] The type of 3D printer or printing material is a factor that can change the durability of the guide template. If the type of 3D printer or printing material is changed by the user, the processor (110) can proceed to step (220) to generate a guide template by applying the changed type of 3D printer or printing material.

[0067] Users can also change the type of 3D printer, printing material, offset of the guide template, and color reference of the color map bar through the user settings screen of FIG. 6.

[0068] Meanwhile, the step (210) of implanting a virtual implant on the matching data in FIG. 2 may be omitted depending on the implementation status of the implant surgery guide template design software.

[0069] For example, when implantation information for a virtual implant (e.g., tooth number to be implanted, implant information, implantation location, etc.) is received from another computer device, the processor (110) may proceed from step (220) of generating a guide template based on the received implantation information for the virtual implant. In this case, the processor (110) may not provide the first item (521) of the user interface, or may transmit a message requesting a change in the implantation location of the virtual implant to the other computer device that transmitted the implantation information, or may run a linked program for changing the implantation location of the virtual implant implanted on the matching data. In this way, the present invention can check the durability of the thickness of the guide template for implant surgery with a color map at the design stage, and through this, it is possible to prevent the guide template from being broken during implant surgery by identifying and correcting in advance a thin durability risk area where the guide template is easily damaged or broken. In addition, the present invention provides a user interface in the form of a pop-up that can immediately change factors affecting the thickness of a guide template when designing a guide template, thereby enabling a user to design a guide template more quickly and accurately.
