Tray for manufacturing implanting guide plate and method for manufacturing implanting guide plate

Abstract

The invention discloses a tray for manufacturing an implanting guide plate and a method for manufacturing the implanting guide plate. The tray comprises a bottom plate, cheek side wing plates and tongue side wing plates; grid lines are arranged on the lower surface of the bottom plate, and radiation positioning eyes are formed in the centers of the grids; the cheek side wing plates are fixedly arranged along the outer edge of the bottom plate; one side of each tongue side wing plate is fixedly arranged along the inner edge of the bottom plate; and an accommodating groove is formed between eachcheek side wing plate and the corresponding tongue side wing plate. The method comprises the following steps: preparing a solid model; taking a dental impression by using the tray; shooting CT of anoral cavity with a tray; carrying out software simulation implanting design; S5, filling a temporary guide plate material into the tray, and forming a guide straight hole in the temporary guide platematerial; and S6, replacing the temporary guide plate material with the guide plate material to finish the implanting guide plate. Or the method comprises the steps of after taking the dental impression with the tray, then shooting CT of the oral cavity with the tray, and carrying out 3D printing on plating of the guide plate by CT data. The tray is favorable for accurately positioning implantingpit points, is suitable for non-flap minimally invasive implantation operation, and has low manufacturing requirements and low cost.

Description

technical field [0001] The invention belongs to the technical field of dental medical instruments, and in particular relates to a tray for making a planting guide plate and a method for making the planting guide plate. Background technique [0002] In clinical stomatology, dental implant is a common treatment method for repairing missing teeth. In order to achieve the purpose of accurately implanting the implant in the alveolar bone, the method of implant surgery guide plate can be used to assist in surgical implant implant placement. At present, the methods for making implant surgery guide plate include simple compression molding method and oral CT scanning 3D printing method. [0003] The simple compression molding method can only determine the implant placement site, but not the direction and depth of the implant placement, which can easily lead to nerve damage and implant lateral penetration of the alveolar bone, and is now basically eliminated. [0004] The 3D printing...

Problems solved by technology

[0007] (3) High production cost

[0008] The root cause of these shortcomings is that the existing oral CT scanning method can accurately display the three-dimensional dimensions of the alveolar bone, but cannot display the outline of the gingiva, and it is difficult to measure the thickness of the gingiva in the edentulous area. Therefore, the 3D printed implant guide plate designed by computer It is only suitable for alveolar bone surface implantation, that is, flap implantation, that is, the gingival mucoperiosteal flap is turned over from the bone surface to implant implants, and it is not possible to make an implant guide for non-flap implantation surgery

[0009] The reason why the existing oral CT scanning methods cannot display the outline of the gums and measure the thickness of the gums in the edentulous area is that, under natural conditions, soft tissues such as the human lips, cheeks, and tongue are in contact with the teeth and gums. Taken together, since the X-ray densities of soft tissues such as lips, cheeks, and tongue are basically the same as those of gums, and the density difference is not large, the existing oral CT scanning methods do not separate soft tissues such as lips, cheeks, and tongue from teeth and gums. Therefore, it is difficult to distinguish gums from soft tissues such as the adjacent lips, cheeks, and tongue on oral CT images, while alveolar bone and teeth are hard tissues, and their X-ray density is significantly higher than that of soft tissues such as lips, cheeks, and tongue. Clearly identified and identified on oral CT images

[0010] Therefore, a new technology is needed to solve the problems in the prior art that the implant guide plate needs flap implantation, complex operation, large trauma, high software and hardware requirements, and high cost
