Description

{Method for picking insertion path setting interface and dental CAD device for same}

The present invention relates to a dental image processing technology, and more particularly, to a technology for designing a prosthesis.

Dental CAD software is software that performs all tasks related to designing objects necessary for dental treatment such as prosthetics, orthodontics, and dentures. Using the Dental CAD software, you can design a prosthesis or move a tooth model. In this case, a situation in which a user has to select a desired object from among various objects on the screen using a mouse or the like frequently occurs in order to perform the corresponding task. However, a lot of inconvenience occurs in the process of the user selecting a specific object, and the accuracy is lowered.

Korean Patent Registration 10-0672325 (Registered on Jan. 16, 2007)

According to an embodiment, in the process of designing the interface for setting the insertion path of the dental CAD software, it is possible to solve and improve the inconvenience and accuracy problems of the interface selection process for the insertion path setting that may occur when the user selects the interface setting for the insertion path setting. We propose a method for selecting an interface for setting an insertion path and a dental CAD device for the same.

A method for selecting an interface for setting an insertion path according to an embodiment includes displaying at least one interface for setting an insertion path on a screen for setting an insertion direction of a prosthesis; and generating a search region based on , and outputting a preset insertion path setting interface on a screen when a preset insertion path setting interface is located in the generated search region.

The method of selecting an interface for setting as insertion may further include displaying the generated search area on a screen.

The method of selecting an interface for setting as insertion may further include enlarging or reducing a search area displayed on the screen.

In the method of selecting an interface for setting as insert, after outputting the interface for setting as set as insert, if a user's cursor movement motion is detected, it is determined that the user does not select the interface for setting with set as insert, and a new setting of the moving cursor on the screen is determined. The method may further include outputting an interface for setting as a new insertion based on the current position.

In the step of generating the search area, an area within a preset range based on the current position of the cursor moving on the screen is created as the search area, and the preset range can be set by the user.

The interface for setting the insertion path may be displayed on the screen in at least one of an arrow shape, a cylindrical shape, a straight line shape, and a handle shape.

The preset insertion path setting interface is an interface for setting the insertion path closest to the current position of the cursor among the insertion path setting interfaces in the search area, and in the step of outputting the preset insertion path setting interface on the screen, the search area Among the interfaces for setting the insertion path in the , the interface for setting the insertion path closest to the current position of the cursor may be output as the highest selection candidate.

In the step of outputting the preset interface for setting the insertion path on the screen, when the interface for setting the insertion path is shown in advance, it may be divided into identifiable visual information and displayed.

The method for selecting an interface for setting an insertion path may further include the step of classifying an undercut region and a margin gap region of an insertion target into identifiable visual information when the interface for setting an insertion path is output.

In the method of selecting the interface for setting the insertion path, when an abnormal region occurs in the direction of the first or previous insertion path, the generated abnormal region is displayed on the screen or a message notifying the occurrence of the abnormality is provided. The method may further include inducing direction correction.

As for the method of selecting the interface for setting the insertion path, when the user modifies the insertion path through the interface for setting the insertion path outputted, the difference between the direction of the insertion path before modification and the direction of the insertion path after modification is divided into identifiable visual information or displayed numerically. The method may further include displaying information.

A method for selecting an interface for setting an insertion path according to another embodiment includes displaying at least one interface for setting an insertion path on a screen for setting an insertion direction of a prosthesis, and selecting an interface for setting an insertion path on the screen. creating a search area based on the current position of the cursor according to a user action; and if the interface for setting as the selected insertion matches the interface for setting as the insertion as preset in the search area, the interface for setting as setting as the selected insertion as the final insertion and selecting an interface for setting.

The method of selecting an interface for setting an insertion path may further include the step of classifying and displaying the interface for setting as an insertion path as identifiable visual information when a preset interface for setting as an insertion path matches the interface setting as an insertion path setting selected in advance.

A dental CAD device according to another embodiment includes an output unit for displaying at least one insertion path setting interface for setting an insertion direction of a prosthesis on a screen, and a user operation moving from the screen to a predetermined insertion path setting interface. An input unit that receives a user manipulation signal according to When positioned, it includes a control unit for outputting a preset interface for setting insertion on the screen through the output unit.

The control unit may divide and display the undercut region and the margin gap region of the insertion target as visible visual information through the output unit when the interface for setting the insertion path is output.

When an abnormal region occurs with respect to the first or previous insertion path direction, the control unit displays the abnormal region on the screen through the output unit or provides a message notifying the occurrence of abnormality, so as to induce correction of the insertion path direction through the insertion path setting interface recommendation can do.

According to the method for selecting an interface for setting the insertion path according to an embodiment and the dental CAD device therefor, when it is necessary to select the interface for setting the insertion path for setting and setting the insertion direction of the prosthesis in the prosthesis design process in the dental CAD software, It eliminates the need for the user to make a selection by moving the on-screen cursor to the correct location on the interface for setting inserts.

For example, when moving to an interface for setting a predetermined insertion on the screen by a user action, a search area is created based on the current position of the cursor and an interface for setting an optimal insertion position located within the created search area (for example, For example, it is recommended to output the closest insertion path setting interface) to the screen based on the current position of the cursor. Accordingly, the user does not need to additionally move the mouse to find an interface for setting the correct insertion path, but only by selecting the interface for setting the optimal insertion path recommended and shown on the current screen at the current mouse position. You will be able to select an interface and proceed with the next operation. This method has two advantages:

First, the user can easily select the correct insertion path setting interface based on the current position of the cursor regardless of the size of the insertion path setting interface displayed on the screen. At this time, the number of tasks such as zoom-in of the screen or setting the camera direction is reduced. In particular, in the process of selecting an interface for setting by insertion displayed as a line, usability and convenience can be greatly improved.

Second, the software automatically analyzes and finds the interface for setting as the closest insertion within the search area based on the current position of the cursor, so even if many GUIs are clustered in a narrow area, the user can move the cursor over the desired GUI and position You don't need to do it, just move the mouse and find the approximate location where the desired GUI is selected and activated. Also, it is possible to obtain the effect of greatly improving the usability and convenience in the process of setting the interface for setting the insertion path.

1 to 3 are diagrams illustrating an interface setting screen for setting an insertion path according to an embodiment of the present invention.

1 to 3, the dental CAD software screens the model object (10-1, 10-2, 10-3) and the interface for setting insertion (12-1, 12-2, 12-3) together. displayed on The model objects (10-1, 10-2, 10-3) and the interface for setting the insertion path (12-1, 12-2, 12-3) correspond to each other in their positions, and may be singular or plural, 1 to 3, each of three cases is illustrated as an example.

Each model object 10-1, 10-2, and 10-3 is data inserted into the prosthesis model, for example, an abutment model. The abutment model is model data obtained by scanning the teeth of a patient after removing the part with cavities and caries. Each of the model objects 10-1, 10-2, and 10-3 may be model data scanned in 3D. The prosthesis model includes a crown, an inlay, an onlay, a coping, and a pontic.

The interface for setting the insertion path (12-1, 12-2, 12-3) is a graphic that can set the insertion direction when inserting each prosthesis model into each model object (10-1, 10-2, 10-3). It is a user interface (Graphic User Interface: GUI, hereinafter referred to as 'GUI'). In this case, 'setting' is used as a concept including all of creation, modification, editing, adjustment, manipulation, and the like. The insertion path setting interfaces 12-1, 12-2, and 12-3 may be expressed in any form indicating an insertion direction. For example, it may be displayed on the screen in the form of an arrow, a cylinder, a straight line, a handle, or the like. The interface for setting the insertion path 12-1, 12-2, 12-3 is a GUI in the form of an arrow penetrating each model object 10-1, 10-2, 10-3 as shown in FIG. As shown in FIGS. 2 and 3, a small GUI in the form of a handle with an arrow and a GUI in a straight line penetrating each model object (10-1, 10-2, 10-3) are combined. can

The insertion path setting operation of the prosthesis is an interface for setting the insertion path while the user sees the object (generally a line) showing the axial direction of the insertion path for each model object (10-1, 10-2, 10-3). (12-1,12-2,12-3) is used to correct the direction of the insertion path. That is, the insertion path setting method using the insertion path setting interface uses a model object, an object (generally a line) showing the axial direction of the insertion path, and an insertion path setting interface on the screen as shown in FIGS. 1 to 3 . output, and after the user selects (eg, clicks) the interface for setting as insertion with a mouse, a method of modifying the direction of insertion using the interface for setting as insertion as selected is used. The general method described above can be organized into sequential continuous operations as follows.

1. Interface for setting the insertion path Model data to be set and the interface for setting the insertion path corresponding thereto are displayed on the screen.

2. The user visually checks the interface for setting the insertion path corresponding to the model data. In this case, the user can adjust the camera view direction or the size of the model in the screen as needed.

3. The user moves the cursor over the interface for setting as insert.

4. After positioning the cursor accurately on the interface for setting as insert, click the mouse at the moved position to select the interface for setting as insert and check the selection result displayed on the screen.

5. If the user-desired insertion interface is not selected correctly, repeat from step 2.

6. If the desired interface for setting as insert is selected correctly, proceed with setting the interface for setting as insert using mouse drag operation.

As shown in FIGS. 1 to 3 , it can be a very difficult and inconvenient task for the user to accurately click the interface for setting as insertion with a mouse. For example, if the GUI indicating the interface for setting by insert is expressed very small or very thin on the screen, it is difficult to perform an accurate selection operation, and additionally, it is necessary to perform additional operations such as magnifying the screen and changing the camera view direction. Even in this way, it is not easy to accurately select the interface for setting with the insertion expressed in the form of a line or the like.

In order to solve the above problems, the present invention provides a process of moving the mouse to an exact position in pixel units, magnifying the screen, converting the camera view direction, etc. We propose a method to quickly and easily select an interface for setting by inserting without the need.

4 is a diagram illustrating the configuration of a dental CAD apparatus according to an embodiment of the present invention.

Referring to FIG. 4 , the dental CAD device 4 performs a CAD process to help prosthetic teeth in actual dentistry. The prosthetic CAD process refers to a series of processes in which a patient's dental data is acquired, a virtual prosthesis model is retrieved from a library through control by a computer program, and then is virtually placed in a target position of the dental data. The tooth data is data having two-dimensional and three-dimensional information on teeth including damaged target teeth. The target position is the target tooth position

The dental CAD device 4 is an electronic device capable of executing software such as prosthesis design software. The electronic device includes a computer, a notebook computer, a laptop computer, a tablet PC, a smart phone, a mobile phone, a personal media player (PMP), and personal digital assistants (PDA). In addition to the prosthesis design software, the software includes a guide program, a scan program, and a medical image processing program. In addition, it can be applied to other general medical software other than for dental prosthetic surgery.

Referring to FIG. 4 , the dental CAD apparatus 4 according to an embodiment includes a data acquisition unit 40 , a storage unit 42 , a control unit 44 , an input unit 46 , and an output unit 48 .

The data acquisition unit 40 acquires image data from a patient. Image data required for prosthetic surgery include CT data and oral model data. The data acquisition unit 40 may execute the CT data and the oral model data in software or load data stored in a web page and a server.

The oral model data is data having information on actual teeth including damaged teeth. The oral model data may be obtained by scanning a plaster model created by imitating a patient's mouth with a 3D scanner. As another example, it may be obtained by scanning the inside of the patient's mouth using a 3D intra-oral scanner. The acquired oral model data may be stored in the storage 42 .

The storage unit 42 stores various data such as information necessary for performing the operation of the dental CAD device 4 and information generated according to the operation. The storage unit 42 according to an embodiment stores the oral model data and CT data of an individual patient, and the user requests the oral model data and CT data of a specific patient from among the entire oral model data and CT data during dental treatment simulation. may be provided to the control unit 44 according to the At this time, the storage unit 42 stores the image of the upper and lower teeth of an individual patient, and sends the image of the upper and lower teeth matched to the oral model data and CT data of a specific patient to the user's request. Accordingly, it may be provided to the control unit 44 . In addition, the storage unit 42 may have a prosthetic library composed of a plurality of prosthetic models, and provide the prosthetic library to the controller 44 .

The controller 44 controls each component while establishing a prosthetic surgery plan through control by computer software. The control unit 44 manages the screen information displayed on the screen through the output unit 48, and performs a simulation of designing and placing a virtual prosthesis to be implanted in a dental image. A dental image in which a virtual prosthesis is placed means a two-dimensional or three-dimensional multidimensional image showing the patient's tooth arrangement created for establishing a prosthetic surgery plan. Various types of images, such as X-ray, CT, panoramic image, scan image, image generated through reconstruction, and image obtained by matching multiple images, can be used for prosthetic surgery planning.

The controller 44 according to an embodiment sets an interface for setting an insertion path for inserting a prosthesis into an insertion target, for example, an abutment model during a prosthesis placement simulation. In this case, the interface for setting the insertion path is a GUI indicating the insertion direction. The control unit 44 proposes a method for allowing the user to easily and accurately select an interface for setting by insertion. For example, the controller 44 detects a current position of a moving cursor on the screen according to a user's motion moving to a setting interface by a predetermined insertion on the screen, and creates a search area based on the detected current cursor position. Then, after searching the preset optimal insertion path setting interface in the search area, the searched optimal insertion path setting interface is output on the screen through the output unit 48 . At this time, if the interface for setting the optimal insertion path matches the interface for setting the insertion path that the user wants to set, the user can click the mouse at the current cursor position without the trouble of moving the mouse to the correct position. , you can select the interface for settings with precise insertion without further mouse movement. By using this method, the user can create and edit the interface for setting by inserting easier, faster, and more efficiently than using the existing method.

The control unit 44 may divide the undercut region and the margin gap region of the insertion target into identifiable visual information through the output unit 48 when outputting the insertion path setting interface. For example, when the insertion target is an abutment, an undercut region and a margin gap region of the abutment according to the insertion path direction of the interface for setting the recommended insertion path may be shown to the user. Accordingly, the user can modify the insertion path direction while simultaneously considering the undercut region and the margin gap region. The undercut region is an area in which the prosthesis model is caught on the insertion target when it is inserted over the insertion target (eg, the abutment model) and a collision occurs. The margin gap region is an edge boundary region where the prosthesis model and an insertion target (eg, abutment model) abut against each other.

When an abnormal region occurs in the direction of the first or previous insertion path, the controller 44 may display the abnormal region on the screen through the output unit 48 or provide a message notifying the occurrence of the abnormality. In this case, when the user wants to correct the direction of the insertion path, the direction of the insertion path may be induced through the above-described interface recommendation process for setting the insertion path. As an example of judging the occurrence of an abnormal region, when the amount of undercut of the undercut region of the insertion target exceeds a preset amount, when the margin line of the margin gap region differs from the optimal margin line by more than a preset interval, it can be determined that an abnormal region has occurred. have.

When the user corrects the insertion path through the interface for setting the optimal insertion path, the control unit 44 divides the difference between the direction of the insertion path before modification and the direction of the insertion path after modification into visual information that can be identified through the output unit 48 . can be displayed or displayed as numerical information. For example, the direction of the insertion path before correction and the direction of the insertion path after correction may be displayed together. Alternatively, the corrected angle, length, etc. may be displayed numerically.

The input unit 46 receives a user manipulation signal. For example, a user manipulation signal for selecting an interface for setting by inserting on the screen may be input. In addition, a user manipulation signal for moving the position of the cursor on the screen may be input. The user manipulation signal may be input by a user action through a pointing device, and the pointing device includes all input devices such as a mouse, a keyboard pen, and a touch screen. Examples of the user operation include an operation in which a user moves a cursor on a screen by using a mouse, an operation in which a user selects an interface for setting by a predetermined insertion on the screen through a pen or a touch on a touch screen type screen, and the like.

5 is a diagram illustrating a flow of a method for selecting an interface for setting an insertion path according to an embodiment of the present invention.

Referring to FIG. 5 , the software displays at least one insertion path setting interface for setting the insertion direction of the prosthesis on the screen (S51). Then, the software detects the current position of the cursor moving on the screen according to the user's movement to the interface for setting by a predetermined insertion on the screen (S52).

Then, the software creates a search area based on the detected current position of the cursor (S53). The search area is an area formed within a preset distance from the current position of the cursor as a center point. For example, a circle or a sphere having a certain radius based on the current position of the cursor may be defined as the search area. The preset distance can be set by the user. In this case, the software may display the search area on the screen. Furthermore, the search area can be enlarged or reduced. For example, when the interface image for setting the insertion path is unclear and difficult to clearly distinguish, the search area 66 may be reduced to improve accuracy.

Then, the software searches the interface for setting as the preset optimal insertion within the generated search area (S54). The interface for setting the optimal insertion path may be an interface for setting the insertion path closest to the current position of the cursor in the search area.

Then, the software outputs an interface for setting as the searched optimal insertion (S55). The user visually checks the part that is determined as the interface for setting with the insertion to be set, and then moves the cursor to the interface for setting with the confirmed insertion. The cursor moves to the interface for setting with the confirmed insertion Before the following, the software outputs the interface for setting the optimal insertion in the search area in the form of a preview on the screen in the step of outputting the interface for setting the insertion path ( S55 ). At this time, if the interface for setting the optimal insertion path shown on the screen is the interface for setting the insertion path that the user wants to set, there is no need to move the cursor to the interface for setting the optimal insertion path anymore, and the user selects at the current cursor position You can select the interface for setting as the optimal insertion through (for example, clicking the mouse) and check the selection result displayed on the screen. On the other hand, if the interface for setting the optimal insertion path shown on the screen is not satisfactory, the user continues to move to the part of the interface for setting the insertion path desired by the user. The process of searching the interface for setting as a new insertion based on the new current location is repeated, and the process of showing the interface for setting as a new insertion in advance on the screen is repeated.

In the step of outputting the interface for setting the insertion path ( S55 ), the software may classify and display the interface for setting the optimum insertion path with identifiable visual information. To this end, a function or UI for outputting the search results in a preview format on the screen when the interface for setting the optimal insertion method searches within the search area should be provided so that the user can check them. At this time, the method for displaying the interface for setting as optimal insertion into identifiable visual information is a method of displaying by changing the external expression of at least one of color, shape, size, area, thickness, and emphasis of the selection candidate. have.

Furthermore, the software can display the undercut area and the margin gap area of the insertion target by distinguishing them as visible visual information when outputting the interface for setting the optimal insertion path. For example, when the insertion target is an abutment, an undercut region and a margin gap region of the abutment according to the insertion path direction of the interface for setting the recommended insertion path may be shown to the user. Furthermore, the user can modify the insertion path direction through the recommended insertion path setting interface while considering the undercut region and the margin gap region at the same time.

The software may display an abnormal region on the screen or provide a message notifying the occurrence of an abnormality when an abnormal region occurs in the direction of the first or previous insertion path. In this case, when the user wants to correct the direction of the insertion path, the insertion path direction may be induced through the recommendation of an interface for setting the insertion path. As an example of judging the occurrence of an abnormal region, when the amount of undercut of the undercut region of the insertion target exceeds a preset amount, when the margin line of the margin gap region differs from the optimal margin line by more than a preset interval, it can be determined that an abnormal region has occurred. have.

Furthermore, when the user modifies the insertion path through the interface for setting the optimal insertion path, the software may display the difference between the direction of the insertion path before modification and the direction of the insertion path after modification as identifiable visual information or display numerical information. can For example, the direction of the insertion path before correction and the direction of the insertion path after correction may be displayed together. Alternatively, the corrected angle and length may be displayed.

6 is a diagram illustrating a flow of a method for selecting an interface for setting an insertion path according to another embodiment of the present invention.

In the method for selecting an interface for setting an insertion path described above with reference to FIG. 5, the software searches for an interface for setting an optimum insertion path while the user moves from the screen to an interface for setting a predetermined insertion path, and the user selects the optimal insertion path. Before moving to the setting interface, it is a method of displaying the setting interface with the optimal insertion in a preview method. On the other hand, in the method of selecting an interface for setting as insertion path described with reference to FIG. 6, when an error occurs when a user selects an interface for setting as insertion path on the screen (for example, the interface for setting setting as insertion path is selected) If the interface for setting as insertion as the user intended is not the interface for setting as the insertion as the user intended, when the interface for setting as setting as the selected insertion is not the interface for setting as the optimum insertion, etc.) Correct the error and set the interface for setting as the optimal insertion as a candidate insertion A way to display the interface.

More specifically, referring to FIG. 6 , the software displays at least one insertion path setting interface for setting the insertion direction of the prosthesis on the screen ( S61 ).

Then, the software detects the current position of the cursor according to a user action of selecting an interface for setting as a predetermined insertion on the screen (S62). In this case, the user action corresponds to an action of selecting an interface for setting as an insertion that the user wants to set on the screen with a mouse click or the like.

Then, the software creates a search area based on the detected current position of the cursor (S63). In this case, the generated search area may be displayed on the screen. Furthermore, the search area can be enlarged or reduced.

Then, the software searches the interface for setting as the preset optimal insertion within the generated search area (S64).

Then, the software determines whether the searched optimal insertion path setting interface matches the selected insertion path setting interface (S65). At this time, if they do not match (S66), the interface for setting the insertion path is recommended in such a way that the interface for setting the searched optimal insertion path is displayed on the screen (S67). On the other hand, if the searched interface for setting as the optimal insertion matches the interface for setting as the selected insertion (S66), the interface for setting as setting as the selected insertion is selected as the interface for setting as the final insertion (S68) and the function to set as insert immediately can be activated

7 is a diagram illustrating a screen for generating a search area for selecting an interface for setting an insertion path according to an embodiment of the present invention.

Referring to FIG. 7 , when the software enters the interface setting screen for setting the insertion path, model objects 10-1, 10-2, and 10-3 and the interfaces for setting the insertion path 12-1, 12-2, 12 -3) is displayed on the screen. In FIG. 7 , an environment for setting the setting interfaces 12-1, 12-2, 12-3 with three inserts corresponding to the three model objects 10-1, 10-2, and 10-3 is shown as an example.

The software detects the current position of the cursor 14 moving on the screen according to a user's movement from the insertion path setting interface setting screen to a predetermined insertion path setting interface. Then, the search area 16 is set based on the detected current position of the cursor 14 . The search area 16 for selecting the interface for setting the insertion path can be defined in various ways and forms as needed. For example, an area within a preset range based on the current position of the cursor 14 may be set as the search area 16 . In FIG. 7 , a circle or a sphere having a predetermined radius based on the current position of the cursor 14 is defined as a search area. The search area 61 may be displayed on the screen and may be enlarged or reduced. A preset range of the search area 61 can be set by a user.

8 is a diagram illustrating a screen for searching and recommending an interface for setting an optimal insertion method within a search area according to an embodiment of the present invention.

Referring to FIG. 8 , the software searches for an interface for setting a preset optimal insertion path within the generated search area 16 and recommends the searched interface for setting an optimal insertion path in advance on the screen. The interface for setting the optimal insertion path is the interface for setting the most suitable insertion path among the interfaces for setting the insertion path included in the search area 16 . The interface 12-2 for setting the second insertion path within. In FIG. 8 , one insertion path setting interface 12-2 is located in the search area 16. However, if a plurality of insertion path setting interfaces are formed in the search area 16, one of the multiple insertion path setting interfaces is selected. An interface for setting an insertion path closest to the current position of the cursor 14 may be recommended as an interface for setting an optimal insertion path.

The software can select the interface for setting as the final insertion without any further mouse movement according to the user's selection action for the interface for setting as the optimal insertion as recommended at the current position of the cursor 14, and when selected, the function to set as insertion will activate

When the software outputs the interface for setting the optimal insertion in a preview format, it can be displayed separately as identifiable visual information. For example, an appropriate method can be applied such as changing the color of the interface for settings to be displayed differently or showing it by increasing the size for optimal insertion. In FIG. 8 , a method for highlighting and highlighting the thickness of the interface for setting the second insertion path 12-2, which is an interface for setting the optimal insertion path recommended by software, is illustrated as an example.
