Hereinafter, a configuration of a guide design device for implant surgery having the above-described characteristics will be described with reference to the configuration of FIG. 1.

Referring to FIG. 1, the guide design apparatus 1 for implant surgery according to an embodiment includes a data acquisition unit 10, a storage unit 12, a control unit 14, an input unit 16, and an output unit 18. Include.

The data acquisition unit 10 acquires basic image data of a patient. The basic image data includes X-ray data, CT data, and oral model data. The data acquisition unit 10 may execute basic image data in a program or load data stored in a web page and a server. CT data, oral model data, etc. may be required as basic data for implant placement.

Oral model data can be obtained by scanning a gypsum model created after the patient's mouth with a 3D scanner, or by scanning the inside of the patient's mouth using a 3D intra-oral scanner. have. CT data can be obtained by generating a patient's head tomography images using computed tomography (CT), segmenting the boundary of the tooth from each tomography image, and then combining them into one. The obtained oral model data and CT data may be stored in the storage unit 12.

The storage unit 12 stores information necessary for performing an operation of the guide design device 1 for implant surgery and information generated according to the operation, and provides information upon request of the control unit 14. For example, the storage unit 12 stores the implantation design information and surgery report generated by the control unit 14. The implantation design information includes information on an implantation position and orientation for an implant structure including a fixture, and information on a guide shape. The implantation design information can be used in the surgical guide during the surgical procedure.

Further, the line of the guide area is adjusted by moving at least one point in the guide area based on the moved reference point. For example, the control unit 14 moves the selection position and the reference point located at the shortest distance among the points constituting the line of the guide area to the selection position. Subsequently, after positioning a preset number of surrounding points based on the moved reference point, a new line connecting the moved reference point and the surrounding points may be generated, and the guide area may be adjusted to include the generated new line. The surrounding points that move together with the moved reference point are a predetermined number of points located around both sides of the reference point, and the number is preset and can be manipulated. An embodiment of a method of adjusting a guide area through point selection will be described later with reference to FIGS. 3 to 5.

When) is received, the line of the guide area is adjusted by moving a predetermined number of points located around the reference point before moving with reference to the position where the predetermined reference point has been moved. At this time, the surrounding points moving together with the reference point are a predetermined number of points located around both sides of the reference point, and the number is preset and can be manipulated. An embodiment of a method of adjusting a guide area through point movement will be described later with reference to FIG. 7.

According to the guide area adjustment method through line drawing, the control unit 14 generates a user-defined line by receiving a user manipulation signal through line drawing on the guide area from the input unit 16, and uses the generated user-defined line to the guide area. Adjust the line of the guide area by correcting it according to the shape of The user-defined line includes a start point and an end point, and the position of the start point and the end point may be in contact with the guide area line, may be within the guide area line, or may be outside the guide area line. The controller 14 may adjust the guide area by referring to the positions of the start and end points of the user-defined line so that at least a part of the user-defined line is included in the line of the guide area. At this time, if the start point (or end point) of the user-defined line is not the area where the point within the line of the guide area is located, the control unit 14 is the start point (or end point) of the user-defined line to the point located at the shortest distance from the start point (or end point). Can be moved.

The output unit 18 displays a program screen. The output unit 18 may display data including a real model drill image and drilling guide information in a simulation form. For example, the output unit 18 displays a drill image of a real model in which a drill position and a drill direction are determined in the image data.
