Here, the registered image 43 may be an image displayed as a two-dimensional cross-sectional image by registering the three-dimensional CT image 41 and the oral cavity model 42 shown in FIG. 4.

In some other embodiments related to step S100, the implant surgery guide creation system 100 may determine the boundary line 53-1 of the alveolar bone 53 region in the registration image 43. Referring to the density graph 62 for the alveolar bone region of FIG. 6, the guide generating system 100 for implant surgery selects a plurality of cells with the highest density within the alveolar bone 53 region on the cross-sectional line 60 of the registration image 43. Points 61-1 and 61-2 can be identified. Here, the vertical axis of the density graph 62 for the alveolar bone region may represent density, and the horizontal axis of the density graph 62 for the alveolar bone region may represent the length of the cross-sectional line 60 shown in the left registered image 43.

The guide generation system for implant surgery 100 detects a plurality of points with the highest density in each cross-sectional image of the registration image 43, and creates an imaginary line connecting the plurality of detected points as the boundary line of the alveolar bone region ( 53-1).

For example, the density graph 62 for the alveolar bone region shown in FIG. 6 is a graph continuously showing the density of points existing on the cross-section line 60 of the left registration image 43, and Among the points present in , a plurality of points (61-1, 61-2) with the highest density can be used to determine the boundary line (53-1) of the alveolar bone (53) area. The shape of the boundary line 53-1 of the alveolar bone 53 region can be clearly understood with reference to FIG. 5. In the art, the plurality of points (61-1, 61-2) with the highest density within the alveolar bone (53) region may be used interchangeably with terms such as 'cortical bone' region.

Based on the location, it shows a cross section about the mesiodistal axis based on the implant axis, and the BA 26 screen shows a cross section about the buccolingual axis based on the implant axis for tooth number 26.

For example, the implant surgery guide creation system 100 can determine the implant placement location by checking anatomical structures from CT images or oral models, and can check adjacent tooth information, gum margin information, and opposing tooth information.

The guide generation system 100 for implant surgery may arrange virtual crowns in the area on the registration image corresponding to the implant placement location based on this information.

Additionally, the guide generation system for implant surgery 100 may determine a position moved by about 3.0 mm from the gum border to the alveolar bone area as the virtual implant placement position based on the long axis of the arranged virtual crowns.

In addition, the guide generation system 100 for implant surgery can determine the virtual implant installation direction to be parallel to the tooth axis of the tooth located in the mesial direction, and in the case of an implant with an adjacent tooth installed, the central axis of the implant is The virtual implant placement direction can be determined to be parallel.

The drilling hole 92 may be a structure on a guide for implant surgery that is perforated so that a tissue punch and drill for incisionless implant surgery can be inserted. The drilling hole 92 may be created by the guide generating system for implant surgery 100 based on the implant placement position and implant placement direction determined by the guide generating system for implant surgery 100 .

In step S220, the implant surgery guide generating system 100 may generate the final shape of the first guide shape. The final shape of the first guide shape may be understood as a shape that includes the mass insertion guide in the initial shape of the first guide shape.

In some embodiments related to step S220, referring to FIG. 10, the guide creation system for implant surgery 100 may define a gum incision line 101 in the oral cavity model 42 of a patient subject to implant surgery. Here, the gum incision line 101 may be defined by connecting a plurality of points designated by the user through a mouse click on the oral model 42 through an input device provided in the user terminal 300. However, the input device may be provided in the guide generating system 100 for implant surgery.

In some other embodiments related to step S220, the implant surgery guide creation system 100 may modify the shape of the gum incision line 101 based on a value input by the user through the user terminal 300.

In some other embodiments related to step S220, as shown in FIG. 11, the guide generating system 100 for implant surgery creates an initial shape of the first guide shape based on the defined gum incision line 101. The final shape of the first guide shape can be created by creating the mass insertion guide 111.

According to this embodiment, the person performing the implant surgery may achieve the effect of shortening the time required to cut the gums by using the mass insertion guide 111 in a situation where the gums must be cut during the incisionless implant surgery.

In some other embodiments related to step S220, the guide generating system for implant surgery 100 may determine the height of the mass insertion guide 111 in the gum-to-tooth root direction based on the thickness of the gum region. Here, the height of the mass insertion guide 111 in the gum-to-alveolar bone direction may be determined based on the mass insertion depth 132 and the mass blade length 131 set by the user, shown in FIG. 13. Here, FIG. 13 may be a user interface screen where the user presets values that serve as a standard for manufacturing a guide for implant surgery. The standard values for manufacturing the mass insertion guide 111, which is a component of the guide for implant surgery, may include the depth at which the mass is inserted into the gums 132, the mass offset 133, and the mass blade length 131.

For example, as shown in FIG. 13, when the mass insertion depth 132 is set to 0.2 mm by the user, the height in the alveolar bone direction from the gum is the area excluding the gum 0.2 mm at the top based on the mass blade length 131. Until the mass can be determined to be inserted. Here, the mass blade length 131 may be predefined depending on the type of mass blade, and may mean the length to the lower end of the area where the mass blade and the mass blade holder are fastened.

In some other embodiments related to step S220, the offset at which the mass insertion guide generated in the first guide shape is generated may be determined based on the mass offset 133 value set by the user shown in FIG. 13. there is.

In some other embodiments related to step S220, referring to FIG. 14, the implant surgery guide generating system 100 adjusts the height 111-1 at which the mass insertion guide is created to that of the drilling hole 92 of the mass insertion guide. It can be adjusted to be the same as the height.

If the height 111-1 of the mass insertion guide is higher than the height of the drilling hole 92, a problem may occur in which the drill required for the implant surgery process cannot be inserted. According to this embodiment, the guide generating system 100 for implant surgery may achieve the effect of avoiding the above problem by adjusting the height of the mass insertion guide 111-1.

Hereinafter, the description will continue with reference to FIG. 3.

In step S300 shown in FIG. 3, the guide generating system 100 for implant surgery may generate a second guide shape. In order to explain the step of generating the second guide shape in more detail, it will be described with reference to FIGS. 15 and 16. Here, the second guide shape may be understood as a partial region deleted from the first guide shape created in step S200 so as to include the shape of the gum cut along the gum incision line.

In step S310 shown in FIG. 15, the guide creation system for implant surgery 100 allows the implant surgery performer to virtually create the shape of the gum cut along the gum incision line 101 by inserting a mass into the mass insertion guideline. You can. Hereinafter, the method for creating the shape of the gum will be described in detail with reference to FIG. 16.

In some embodiments related to step S310, the guide generating system for implant surgery 100 inserts a mass preset by the user, shown in FIG. 13, to create a virtual incised gum shape 161 along the gum incision line 101. It can be generated based on the depth 132, the direction of bending of the incised gums 135, and the compression rate of the gums 134. Here, the bending direction 135 of the incised gum may be set to be one of the buccal direction, the lingual direction, or the buccal and lingual directions, as shown in FIG. 13.

In addition, the degree of compression of the gums 134 may refer to the degree to which the gums are depressed when the guide for implant surgery is attached to the oral cavity of a patient subject to implant surgery. Therefore, the thickness of the cut gum shape 161 can be determined based on the degree of compression of the gums 134. For example, assuming that the original thickness of the gum is 100%, the cut gum shape 161 may have a thickness of 50% of the original thickness of the gum, as set in FIG. 13.

In some other embodiments related to step S310, the user may use the incised gum shape 161 generated by the guide generation system 100 for implant surgery to determine the mass insertion depth 132 and blade information 131-1 shown in FIG. 13. ), can be modified by resetting the degree of gum compression (134) and gum retraction direction (135). In addition, of course, the incised gum shape 161 generated by the guide generating system 100 for implant surgery can be displayed to the user through the user terminal 300.

In step S320, the guide generating system for implant surgery 100 may generate a second guide shape by adjusting the first guide shape based on the incised gum shape 161. The second guide shape may also be understood as the final shape of the guide for implant surgery.

In some embodiments related to step S320, as shown in FIG. 16, the guide generating system 100 for implant surgery combines the incised gum shape 161-1 to couple the incised gum shape 161-1 to the first guide shape. By creating the portion 162, a second guide shape can be created. Here, the cut gum shape 161-1 can be understood as a virtual gum shape that predicts the shape obtained by the implant surgery guide generating system 100 cutting the gum area 161 of the registration image. Additionally, the incised gum coupling portion 162 may be a region removed from a portion of the first guide shape so that the incised gum shape 161 can be included inside the guide for implant surgery.
