Abstract

The invention discloses an oral implantation positioning device for an edentulous jaw. The oral implantation positioning device comprises a front end fixing part, a rear end extending part and a sleeve, wherein the front end fixing part is connected with the sleeve through a first connecting assembly; the rear end extending part is connected with the sleeve through a second connecting assembly; a guide rail groove is formed in the rear end extending part; the sleeve is movably arranged in the guide rail groove through the second connecting assembly; the front end fixing part is arranged to be a plate-shaped piece in a dental arch shape and is fixed on the edentulous jaw; the rear end extending part is a plate-shaped piece extending in the direction far away from the front end fixing part, and the shape of the rear end extending part is subjected to radian setting based on the actual dental arch shape; and the guide rail groove extends in the extending direction of the rear end extending part. According to the specific positions, corresponding to the front end fixing part and the rear end extending part, in the oral cavity of a patient, the deflection angle and position setting of the sleeve can be fixed in advance so as to preset the implantation inclination angle and the implantation position; and meanwhile, an implantation guide plate is formed through the sleeves with different diameters, the direction and position of a drill bit are limited, and implantation of the preset implant is completed.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an edentulous oral cavity implant positioning device. Background technique [0002] In recent years, edentulous patients account for a considerable proportion of oral implant restoration, and various implant restoration schemes have been used to restore the stomatognathic system of edentulous patients. The implantation plan is formulated by analyzing the patient's basic information, clinical data, imaging data, digital photos, and functional data before the operation. At present, the mainstream method of edentulous implant surgery is to use free hand implantation. [0003] In the existing free-hand implantation for edentulous implant surgery, in order to reduce the cantilever, the method of distal implantation is generally inclined. The doctor designs the implant site according to the patient's clinical and auxiliary examination before operation. However, the angle and...
