Description

Method for providing a user interface for fabricating prostheses and a computer-readable recording medium having a program for executing the same on a computer

[0001] The present invention relates to a method for providing a user interface for fabricating a prosthesis and a computer-readable recording medium having a program for executing the method on a computer. More specifically, the invention relates to a method for providing a user interface for fabricating a prosthesis that enables intuitive and convenient creation and editing of the prosthesis, and a computer-readable recording medium having a program for executing the method on a computer.

[0002] 3D oral data refers to data obtained by scanning teeth and the oral cavity with a 3D scanner. Dental treatments such as prosthetic treatments like inlays, onlays, and crowns, as well as implants and orthodontics, can acquire the patient's oral data and use it for designing prosthetics or implants, fabricating braces, etc.

[0003] While most of these dental prostheses were traditionally produced manually, they are now being designed using 3D CAD software. The information and interactions that users are required to input during the prosthesis design process vary depending on the CAD software product. To use 3D CAD software, users are required to input information regarding the preprocessing of 3D oral data, the prosthesis design process, and post-design completion tasks, as well as input for interactions. As the amount of information users must input during this prosthesis design process increases, the time and resources required to design prostheses are growing significantly.

[0004] The objective of the present invention is to provide a method for providing a user interface for fabricating a prosthesis that allows the design of the prosthesis to be checked intuitively and immediately.

[0005] Another objective of the present invention is to provide a computer-readable recording medium on which a program for executing it on a computer is recorded.

[0006] However, the problem that the present invention aims to solve is not limited to the problem mentioned above, and may be expanded in various ways without departing from the spirit and scope of the present invention.

[0013] In one embodiment, the parameter adjustment unit further includes a fifth parameter adjustment unit for adjusting a margin width defined as the width of a portion of the prosthesis adjacent to the margin line, and in the step of highlighting the portion within the guide image, when the fifth parameter adjustment unit is selected by the user, an enlarged area of ​​the margin line within the guide image and a fifth portion corresponding to the margin width within the enlarged area may be highlighted.

[0014] In one embodiment, the parameter adjustment unit further includes a sixth parameter adjustment unit for adjusting a margin angle defined as the inclination angle of a part of the prosthesis extending from the margin line, and in the step of highlighting the part within the guide image, when the sixth parameter adjustment unit is selected by the user, an enlarged area of ​​the margin line within the guide image and a sixth part corresponding to the margin angle within the enlarged area may be highlighted.

[0015] In one embodiment, the parameter adjustment unit further includes a seventh parameter adjustment unit for adjusting the occlusal distance between the prosthesis and the opposing tooth, and in the step of displaying the opposing tooth or the adjacent tooth, if the seventh parameter adjustment unit is selected by the user, the opposing tooth arranged to face the prosthesis may be displayed in the guide image.

[0016] In one embodiment, the parameter adjustment unit further includes an eighth parameter adjustment unit for adjusting the distance between the prosthesis and the adjacent tooth, and in the step of displaying the opposing tooth or the adjacent tooth, when the eighth parameter adjustment unit is selected by the user, the adjacent tooth arranged adjacent to the side of the prosthesis may be displayed on the guide image.

[0017] In one embodiment, the step of displaying the selection parameter image on the guide image may further include the step of providing a modified guide image corresponding to the parameter modified by the user.

[0018] In one embodiment, the parameter adjustment unit includes a third parameter adjustment unit for adjusting the minimum thickness of the prosthesis, and in the step of providing the modified guide image, if the user modifies the parameter for the minimum thickness of the prosthesis using the third parameter adjustment unit, the thickness of the prosthesis in the guide image can be changed immediately.

[0019] In one embodiment, the parameter adjustment unit includes a fourth parameter adjustment unit for adjusting the minimum height between the lowest part of the cement gap, which is defined as a space where an adhesive layer is placed between the prepared tooth and the inner surface of the prosthesis, and the margin line of the prosthesis. In the step of providing the modified guide image, if the user modifies the parameter for the minimum height between the lowest part of the prosthesis and the margin line using the fourth parameter adjustment unit, a virtual line passing through the lowest part of the cement gap in the guide image can be moved immediately.

[0020] In one embodiment, the method may further include the step of providing a tool selection unit for selecting a processing tool to be used for creating the prosthesis.

[0021] In one embodiment, in the step of providing the tool selection unit, if a milling method within the tool selection unit is selected by the user, a ninth parameter adjustment unit for adjusting the radius of the processing tool may be provided to the user.

[0022] In one embodiment, the step of generating a three-dimensional image of the prosthesis may include the step of generating a first image which is a three-dimensional image of the inner surface of the prosthesis and the step of generating a second image which is a three-dimensional image of the outer shape surrounding the inner surface of the prosthesis.

Accordingly, the user can intuitively and conveniently recognize the portion where each of the parameters is modified using the user interface. Accordingly, the convenience and accuracy of the fabrication process of the prosthesis are improved, and the time and cost of the fabrication process of the prosthesis can be reduced.

[0025] In addition, the guide image modified in correspondence with the parameters modified by the user can be provided immediately. Accordingly, since the user can more intuitively perceive the fabrication process of the prosthesis using the user interface, the accuracy of the prosthesis fabrication can be further improved and the fabrication time can be further shortened.

[0044] FIG. 1 is a flowchart illustrating a method for providing a user interface for fabricating a prosthesis according to an embodiment of the present invention. FIG. 2 is a flowchart illustrating an example of a step of displaying a selected parameter image on a guide image to explain a parameter selected by the user of FIG. 1. FIG. 3 is a drawing illustrating a user interface provided through the method for providing a user interface of FIG. 1.

[0045] Referring to FIGS. 1 to 3, a method for providing a user interface for manufacturing a prosthesis according to an embodiment of the present invention may include the steps of: providing a guide image (200) that visualizes the inner surface of the prosthesis (S100); providing a tool selection unit (400) for selecting a processing tool to be used to create the prosthesis (S200); providing a parameter control unit (S300) for controlling parameters for creating the prosthesis; displaying a selection parameter image on the guide image (200) to explain the parameter selected by the user (S400); and creating a three-dimensional image of the prosthesis (S500).

[0046] The step (S400) of displaying the selected parameter image on the guide image (200) to explain the parameter selected by the user may include the step (S420) of highlighting a portion within the guide image (200) corresponding to the parameter selected by the user, and the step (S440) of displaying a corresponding value or an adjacent value to explain the parameter selected by the user.

[0047] In one embodiment, the method for providing a user interface for manufacturing a prosthesis may be performed by a computing device. In one embodiment, the computing device may be an electronic device that implements a user interface (100) through a dental CAD (computer aided design) program. For example, the electronic device may be a mobile phone, video phone, smart pad, tablet PC, desktop, laptop, etc., for providing the user interface (100) to a user. However, the type of computing device for manufacturing a prosthesis according to the embodiments of the present invention is not limited thereto.

[0048] In one embodiment, the electronic device may perform a CAD process to assist in actual dental treatment, e.g., dental prosthetics and implants. The CAD process may be a series of processes including acquiring the patient's three-dimensional oral data, receiving a virtual tooth model from a library through control by a computer program, virtually placing it at a target location in the three-dimensional oral data, and setting parameters for a prosthetic to be used on the tooth model. The three-dimensional oral data is data containing three-dimensional information of teeth including a damaged target tooth, and the target location may be the location of teeth arranged in the dental arch included in the three-dimensional oral data.

[0049] The electronic device may include a data storage unit that acquires and stores the three-dimensional oral data of the patient, an input unit that receives an input signal from the user, an output unit that displays a user interface (100) on a screen based on the input signal, and a CAD control unit that controls the input signal and transmits an output signal to the output unit.

[0050] In one embodiment, the 3D oral scan data may be mesh data including 3D vertices and triangles or rectangles generated by connecting the vertices. Additionally, the 3D oral scan data may be image data captured through a 3D scanner. There are no restrictions on the file extension of the 3D oral scan data, and it may be, for example, one of ply, obj, or stl. Furthermore, the CT data and the MRI data may each include 2D image data and 3D volume data.

[0051] The data storage unit may store various data, such as information necessary for performing the operation of the electronic device and information generated according to the performance of the operation. In one embodiment, the data storage unit stores the three-dimensional oral data of an individual patient, and during the dental treatment simulation process, the three-dimensional oral data of a specific patient among all three-dimensional oral data may be provided to the CAD control unit upon the user's request. For example, images of the patient's upper dentition and lower dentition stored in the data storage unit may be provided to the CAD control unit upon the user's request.

[0052] The input unit may receive operation signals from the user. For example, the input unit may generate input signals as command signals, such as the user's action of selecting a specific area within the user interface (100) or the user's action of selecting areas displayed on the output unit. In one embodiment, the input unit may be an input device, such as a mouse or a touch panel, for transmitting the command signals to the CAD control unit. However, the type of the input unit according to the embodiments of the present invention is not limited thereto.

[0053] The above CAD control unit controls functional units (e.g., the data storage unit, the input unit, and the output unit) while performing the CAD process through control by a computer program. For example, the above CAD control unit may include a processor for implementing the CAD program in the electronic device and a memory for storing instructions for executing the CAD program.

[0054] The CAD control unit displays images of the patient's three-dimensional oral data on the screen through the output unit. For example, the CAD control unit may display normal teeth, prepared teeth for which dental treatment is to be performed, and opposing teeth (opposite teeth) or adjacent teeth corresponding to the prepared position through the output unit.

[0055] Here, the prepared tooth may refer to a tooth prepared for a crown, and the prepared tooth may refer to a tooth from which a portion has been shaved. Specifically, to create a single crown, a process is required to shave down the entire natural tooth to make it easier to place a prosthesis, and a natural tooth that has undergone this process can be referred to as the prepared tooth.

[0056] The output unit receives the output signal from the CAD control unit and can display images (e.g., guide image (200), parameter control unit and tool selection unit (400)) on the user interface (100). In one embodiment, the output unit may be a television for displaying the user interface (100), or may include a computer monitor, a laptop computer screen, a tablet screen, etc. However, the types of the output unit according to the embodiments of the present invention are not limited thereto.

[0057] The user interface (100) may be an interface that is displayed on the output portion of the electronic device and visually provided to the user. The user interface (100) may include a guide image (200), the parameter adjustment unit, and the tool selection unit (400). The parameter adjustment unit may include a first parameter adjustment unit (310), a second parameter adjustment unit (320), a third parameter adjustment unit (330), a fourth parameter adjustment unit (340), a fifth parameter adjustment unit (350), a sixth parameter adjustment unit (360), a seventh parameter adjustment unit (370), and an eighth parameter adjustment unit (380).

[0058] In one embodiment, through a user interface (100), the user may simultaneously receive a guide image (200), a first parameter adjustment unit (310), a second parameter adjustment unit (320), a third parameter adjustment unit (330), a fourth parameter adjustment unit (340), a fifth parameter adjustment unit (350), a sixth parameter adjustment unit (360), a seventh parameter adjustment unit (370), an eighth parameter adjustment unit (380), and a tool selection unit (400).

[0059] In one embodiment, the step (S200) of providing a tool selection unit (400) for selecting the processing tool to be used for creating the prosthesis may be performed prior to the step (S300) of providing a parameter adjustment unit for adjusting the parameters for creating the prosthesis and the step (S400) of displaying the selected parameter image on the guide image (200) to explain the parameters selected by the user. For example, the user may adjust the parameters for creating the prosthesis after selecting the processing tool.

[0060] However, the order in which the step (S200) of providing a tool selection unit (400) for selecting a processing tool to be used for creating the prosthesis according to the embodiments of the present invention and the step (S400) of displaying the selection parameter image on the guide image (200) to explain the parameter selected by the user are each performed is not necessarily limited thereto.

[0061] The step (S500) of generating a three-dimensional image of the above-mentioned prosthesis can generate a three-dimensional image of the above-mentioned prosthesis based on data set in the parameter adjustment unit. Details regarding this will be described later with reference to FIGS. 14 and FIGS. 15.

[0062] The guide image (200) may be an image visualizing the inner surface of the prosthesis. For example, the guide image (200) may include a prepared tooth, the prosthesis to be placed on the prepared tooth, and regions between the prepared tooth and the prosthesis.

[0063] The parameter control unit may be part of a user interface (100) for controlling a plurality of parameters for creating the prosthesis. In one embodiment, the first parameter control unit (310) may be part of the parameter control unit for controlling a cement gap defined as a space in which an adhesive layer is disposed between the prepared tooth and the inner surface of the prosthesis. The adhesive layer may be an adhesive for bonding the prosthesis to an abutment tooth (e.g., the prepared tooth). For example, the adhesive may include acrylic resin, polymethyl methacrylate (PMMA), etc. These may be used alone or in combination. However, the material included in the adhesive layer disposed in the cement gap according to the embodiments of the present invention is not necessarily limited thereto and may include various types of adhesive materials.

[0064] In one embodiment, the second parameter adjustment unit (320) may be part of the parameter adjustment unit for adjusting an adaptive extra gap between the cement gap and the inner surface of the prosthesis. The adaptive extra gap may be a space additionally created in the right angle portion of the abutment tooth to form a stable inner surface of the prosthesis.

[0065] In one embodiment, the third parameter adjustment unit (330) may be part of the parameter adjustment unit for adjusting the minimum thickness of the prosthesis. The minimum thickness may be the thickness of the prosthesis to prevent fracture of the prosthesis.

[0066] In one embodiment, the fourth parameter adjustment unit (340) may be part of the parameter adjustment unit for adjusting the minimum height between the lowest part of the cement gap and the margin line of the prosthesis. The minimum height may be a height for leaving a minimum space between the margin line of the prosthesis and the cement gap.

[0067] In one embodiment, the fifth parameter adjustment unit (350) may be part of the parameter adjustment unit for adjusting the margin width. For example, the margin width may be defined as the width of a part of the prosthesis adjacent to the margin line.

[0068] In one embodiment, the sixth parameter adjustment unit (360) may be part of the parameter adjustment unit for adjusting the margin angle. For example, the margin angle may be defined as the angle of inclination of a part of the prosthesis extending from the margin line.

[0069] In one embodiment, the seventh parameter adjustment unit (370) may be part of the parameter adjustment unit for adjusting the occlusal distance between the prosthesis and the opposing tooth. In one embodiment, the eighth parameter adjustment unit (380) may be part of the parameter adjustment unit for adjusting the distance between the prosthesis and the adjacent tooth.

[0070] Specifically, the user can adjust the size of the cement gap by adjusting the value displayed in the input window of the first parameter adjustment unit (310). The user can adjust the size of the adaptive additional gap between the cement gap and the inner surface of the prosthesis by adjusting the value displayed in the input window of the second parameter adjustment unit (320). The user can adjust the minimum thickness of the prosthesis to be larger or smaller by adjusting the value displayed in the input window of the third parameter adjustment unit (330). The user can adjust the minimum height between the bottom end of the cement gap and the margin line to be larger or smaller by adjusting the value displayed in the input window of the fourth parameter adjustment unit (340). The user can adjust the margin width to be larger or smaller by adjusting the value displayed in the input window of the fifth parameter adjustment unit (350). The user can adjust the size of the margin angle by adjusting the value displayed in the input window of the sixth parameter adjustment unit (360). The user can adjust the occlusal surface distance so that the distance between the prosthesis and the opposing tooth becomes farther or closer to each other by adjusting the value displayed in the input window of the seventh parameter adjustment unit (370). The user can adjust the distance between the prosthesis and the adjacent tooth so that the distance between the prosthesis and the adjacent tooth becomes farther or closer to each other by adjusting the value displayed in the input window of the eighth parameter adjustment unit (380). However, the number of parameter adjustment units and the function of the parameter adjusted by each of the parameter adjustment units according to the embodiments of the present invention are not necessarily limited thereto.

[0071] The tool selection section (400) may be part of a user interface (100) for selecting a processing tool to be used for creating the prosthesis. For example, the tool selection section (400) may include a first item for a 3D printing method, a second item for a milling method, and a third item. Specifically, the second item may be an item for a milling method using polymethyl methacrylate (PMMA), and the third item may be an item for a milling method using zirconia.

[0072] In one embodiment, the guide image (200) may include parts corresponding to parameters controlled by the parameter control unit. For example, the guide image (200) may include a first part corresponding to a cement gap controlled by the first parameter control unit (310), a second part corresponding to an adaptive additional gap controlled by the second parameter control unit (320), a third part corresponding to a prosthesis having the minimum thickness controlled by the third parameter control unit (330), a fourth part corresponding to a virtual line indicating the minimum height controlled by the fourth parameter control unit (340), a fifth part corresponding to a margin line controlled by the fifth parameter control unit (350), and a sixth part corresponding to a margin angle controlled by the sixth parameter control unit (360).

[0073] In one embodiment, the virtual line may be a dotted line passing through the lowest part of the cement gap. In one embodiment, the fifth part and the sixth part may be parts displayed within an enlarged area of ​​the margin line. Specifically, the fifth part may be indicated as 1 within the enlarged area, the sixth part as 2 within the enlarged area, and the sixth part may be indicated in a color different from that of the fifth part. However, the manner in which each of the first to sixth parts is displayed according to the embodiments of the present invention is not necessarily limited thereto.

[0074] In one embodiment, the guide image (200) may be displayed spaced apart from one side of each of the first to eighth parameter adjustment sections (310, 320, 330, 340, 350, 360, 370, 380) within the user interface (100). In one embodiment, the first to eighth parameter adjustment sections (310, 320, 330, 340, 350, 360, 370, 380) may be displayed at the bottom of the tool selection section (400) within the user interface (100). For example, the first to eighth parameter adjustment sections (310, 320, 330, 340, 350, 360, 370, 380) may be displayed sequentially at the bottom of the tool selection section (400). However, the locations where each of the first to eighth parameter adjustment sections (310, 320, 330, 340, 350, 360, 370, 380), and tool selection section (400) of the guide image (200) according to embodiments of the present invention is displayed are not necessarily limited thereto.

[0075] In one embodiment, the numerical value that can be entered into each of the input windows of the first to sixth parameter control units (310, 320, 330, 340, 350, 360) may be 0 or greater. In one embodiment, the numerical value that can be entered into each of the input windows of the seventh and eighth parameter control units (370, 380) may be 0 or less. In other words, only numerical values ​​having a value of 0 or a positive value may be entered into each of the input windows of the first to sixth parameter control units (310, 320, 330, 340, 350, 360), and only numerical values ​​having a value of 0 or a negative value may be entered into each of the input windows of the seventh and eighth parameter control units (370, 380).

[0076] Specifically, the value that can be entered into the input window of the first parameter adjustment unit (310) may be approximately 0 to approximately 0.2. The value that can be entered into the input window of the second parameter adjustment unit (320) may be approximately 0 to approximately 0.1. The value that can be entered into the input window of the third parameter adjustment unit (330) may be approximately 0 to approximately 1. The value that can be entered into the input window of the fourth parameter adjustment unit (340) may be approximately 0 to approximately 1.5. The value that can be entered into the input window of the fifth parameter adjustment unit (350) may be approximately 0 to approximately 2. The value that can be entered into the input window of the sixth parameter adjustment unit (360) may be approximately 0 to approximately 60. The value that can be entered into the input window of the seventh parameter adjustment unit (370) may be approximately -1 to approximately 1. The value that can be entered into the input window of the 8th parameter adjustment unit (380) can be approximately -0.5 to approximately 0.5.

[0077] However, the range of numerical values ​​input to each of the first to eighth parameter adjustment units (310, 320, 330, 340, 350, 360, 370, 380) according to the embodiments of the present invention is not necessarily limited thereto.

[0078] FIGS. 4 to 9 are drawings for explaining the step of highlighting a part within a guide image corresponding to a parameter selected by the user of FIG. 2.

[0079] Referring to FIGS. 1 to 9, a portion within a guide image (200) corresponding to a parameter selected by the user may be highlighted. For example, if the user selects at least one parameter adjustment portion among the first to sixth parameter adjustment portions (310, 320, 330, 340, 350, 360), a step (S420) of highlighting a portion within a guide image (200) corresponding to the parameter selected by the user may be performed.

[0080] In one embodiment, when the user selects the first parameter adjustment unit (310), the first part corresponding to the cement gap within the guide image (200) may be highlighted. Specifically, when the user selects the input window of the first parameter adjustment unit (310) to adjust the size of the cement gap, the first part may be highlighted. Additionally, text and / or an image for explaining the first part may be displayed. In other words, when the first parameter adjustment unit (310) is selected, the selected parameter image may correspond to the image of the highlighted first part and the text and / or image for explaining the first part.

[0099] However, the default values ​​input to the parameter adjustment units according to the embodiments of the present invention are exemplary and are not necessarily limited thereto.

In one embodiment, the tool image (420) may be displayed above the guide image (200) within the user interface (100).

[0101] Figures 14 and 15 are drawings for explaining the steps of generating a three-dimensional image of the prosthesis of Figure 1.

[0102] Referring to FIGS. 1 to 15, a first image (500), which is a three-dimensional image of the inner surface of the prosthesis, and a second image (600), which is a three-dimensional image of the outer shape surrounding the inner surface of the prosthesis, can be generated based on data set in the parameter adjustment unit. Depending on the user's settings, one of the three-dimensional images of the first image (500) and the second image (600) may be selectively displayed. For example, the second image (600) may be a three-dimensional image representing the outer shape of the crown. However, the shape, type, etc. of the second image (600) according to the embodiments of the present invention is not necessarily limited thereto.

Accordingly, the user can intuitively and conveniently recognize the portion where each of the parameters is modified using the user interface (100). Accordingly, the convenience and accuracy of the manufacturing process of the prosthesis are improved, and the time and cost of the manufacturing process of the prosthesis can be reduced.

[0104] FIG. 16 is a flowchart illustrating another example of the step of displaying a selected parameter image on a guide image to explain the parameter selected by the user of FIG. 1. FIGS. 17 to 19 are drawings illustrating the step of providing a modified guide image corresponding to the parameter modified by the user of FIG. 16.

[0105] The method for providing a user interface for manufacturing a prosthesis described with reference to FIGS. 16 to 19 may be substantially the same or similar as the method for providing a user interface for manufacturing a prosthesis described with reference to FIGS. 1 to 15, except for the step (S460) of providing a guide image modified in correspondence with a parameter modified by the user and the step (S400A) of displaying a selected parameter image on a guide image to explain a parameter selected by the user.

[0106] In the following, content that overlaps with the content described with reference to FIGS. 1 to 15 may be omitted or briefly explained.

[0107] Referring to FIG. 1 and FIG. 16 to 19, a method for providing a user interface for manufacturing a prosthesis according to another embodiment of the present invention may include the steps of: providing a guide image (200) visualizing the inner surface of the prosthesis (S100); providing a tool selection unit (400) for selecting a processing tool to be used to create the prosthesis (S200); providing a parameter adjustment unit (S300) for adjusting the parameters for creating the prosthesis; displaying a selection parameter image (S400A) on the guide image (200A) to explain the parameters selected by the user (S400A); and creating a three-dimensional image of the prosthesis (S500).

[0108] The step (S400A) of displaying the selected parameter image on the guide image (200A) to explain the parameter selected by the user may include the step (S420) of highlighting a portion within the guide image (200A) corresponding to the parameter selected by the user, the step (S440) of displaying a corresponding value or adjacent value to explain the parameter selected by the user, and the step (S460) of providing a modified guide image corresponding to the parameter modified by the user.

[0109] In the step (S460) of providing a modified guide image corresponding to the parameter modified by the user, if the user modifies the value of the parameter, the guide image (200A) may be changed to correspond to the modified value.

[0110] In one embodiment, when the user modifies the parameter for the minimum thickness of the prosthesis using the third parameter adjustment unit (330), the thickness of the prosthesis in the guide image (200A) can be changed immediately. Specifically, when the user modifies the value entered in the input window of the third parameter adjustment unit (330) to be larger than the existing value, the prosthesis in the guide image (200A) can be changed immediately from the first thickness (TH1) to a second thickness (TH2) which is greater than the first thickness (TH1).

[0111] In one embodiment, when the user modifies the minimum height between the lowest part of the prosthesis and the margin line using the fourth parameter adjustment unit (340), the virtual line in the guide image (200A) can be moved immediately. Specifically, when the user modifies the value entered in the input window of the fourth parameter adjustment unit (340) to be smaller than the existing value, the virtual line in the guide image (200A) can be changed immediately to move to a position lower than the existing position.

[0112] In one embodiment, when the user modifies the margin width using the fifth parameter adjustment unit (350), the thickness of the prosthesis corresponding to the margin width in the guide image (200A) can be immediately increased. Specifically, when the user modifies the value entered in the input window of the fifth parameter adjustment unit (350) to be larger than the existing value, a part of the prosthesis adjacent to the margin line in the guide image (200A) can be immediately changed from a first width (W1) to a second width (W2) which is larger than the first width (W1).

[0113] FIGS. 19 to 17 illustrate only the modification of the guide image (200A) according to the modification of the parameters for each of the third to fifth parameter adjustment units (330, 340, 350), but the parameters modified in the step (S460) of providing a modified guide image corresponding to the parameters modified by the user according to embodiments of the present invention are not necessarily limited thereto.

[0114] For example, if the user modifies the parameters for the cement gap using the first parameter adjustment unit (310) of FIG. 3, the image of the cement gap in the guide image (200A) can be changed immediately. Also, if the user modifies the adaptive additional gap using the second parameter adjustment unit (320) of FIG. 3, the image of the adaptive additional gap in the guide image (200A) can be changed immediately. Also, if the user modifies the margin angle using the sixth parameter adjustment unit (360) of FIG. 3, the image of the margin angle in the guide image (200A) can be changed immediately. Also, if the user modifies the occlusal surface distance using the seventh parameter adjustment unit (370) of FIG. 3, the position of the opposing tooth in the guide image (200A) can be changed immediately. Additionally, if the user modifies the distance between the prosthesis and the adjacent tooth using the eighth parameter adjustment unit (380) of FIG. 3, the position of the adjacent tooth within the guide image (200A) can be changed immediately. Additionally, if the user modifies the size of the radius of the processing tool using the ninth parameter adjustment unit (390) of FIG. 12, the image of the processing tool within the tool image (420) can be changed immediately.

[0115] As described above, in the method for providing a user interface for fabricating the prosthesis, the user interface (100A) provides the user with a guide image (200A) that visualizes the inner surface of the prosthesis, provides the user with a parameter control unit for controlling parameters for creating the prosthesis, and can highlight a portion within the guide image (200) corresponding to a parameter selected by the user. Accordingly, the user can intuitively and conveniently recognize the portion where each of the parameters is modified using the user interface (100A). Accordingly, the convenience and accuracy of the fabrication process of the prosthesis are improved, and the time and cost of the fabrication process of the prosthesis can be reduced.

[0116] In addition, a modified guide image (200A) corresponding to the parameters modified by the user can be provided immediately. Accordingly, the user can more intuitively recognize the manufacturing process of the prosthesis using the user interface (100A), thereby further improving the accuracy of the prosthesis manufacturing and further shortening the manufacturing time.

Additionally, the structure of the data used in the above-described method can be recorded on a computer-readable medium through various means.
