The surgical positioning templates in the prior art are mostly made by doctors themselves according to the oral conditions of patients. However, the surgical guide plates made by doctors often do not fit well with the patient’s oral cavity, and the drill sleeves are relatively rough. The degree is not high, and it affects the success rate of artificial dental implant surgery

Embodiment 1
[0029] Follow the steps below to make a guide plate for surgery
[0030] S1. Obtain CBCT (abbreviation of Cone beam CT, cone beam CT) data of the patient's oral cavity according to the existing technology;
[0031] S2. Conduct a comprehensive assessment of the patient's general and oral conditions to ensure that the patient is eligible for implantation;
[0032] S3. Make a plaster model of the patient's oral cavity, obtain the three-dimensional scanning data of the plaster model, and perform registration with the CBCT data in step S1, and reconstruct the three-dimensional model of the teeth and bones of the patient's oral cavity;
[0033] S4. Formulate a corresponding implant plan based on the data obtained in step 1, and perform strength analysis on the selected implant to determine the implant model;
[0034] S5. Design a standardized template corresponding to the guide template drill bit, combine the standardized template with the patient's tooth and bone three-dimensional...

Abstract
The invention discloses a method for designing and preparing a guide plate for dental implant surgery, wherein the method includes the following steps: S1, obtaining patient oral CBCT data; S2, carrying out comprehensive assessment of conditions of a patient whole body and oral cavity; S3, reconstructing a tooth and skeleton three-dimensional model of the oral cavity part of a patient; S4, makinga corresponding implant plan, carrying out strength analysis of an implant, and determining the type of the implant; S5, designing a standardized template, combining the standardized template with thepatient tooth and skeleton three-dimensional model, to obtain an initial guide plate model, selecting the type of the implant, and processing the initial guide plate model into a customized surgicalguide plate three-dimensional model; and S6, according the tooth and skeleton three-dimensional model of the oral cavity part of the patient, determining the size of a guide hole, combining with the customized surgical guide plate three-dimensional model, designing and printing a customized surgical guide plate corresponding to the guide hole, and mounting and fixing a dental drill sleeve for positioning on the guide hole of the customized surgical guide plate. According to the three-dimensional processing data of the surgical guide plate, a personalized base and transitional false teeth can selectively continue to be prepared.
Description
technical field [0001] The invention relates to the technical field of dental implant surgery, in particular to a design and manufacturing method for a guide plate used in dental implant surgery. Background technique [0002] The surgical positioning template of the implant is a tool commonly used in dental implant surgery. It can facilitate the doctor's clinical operation, make the implant position of the gum bone better and avoid the bad, and reduce the suddenness during the operation. variable. The surgical positioning templates in the prior art are mostly made by doctors themselves according to the oral conditions of patients. However, the surgical guide plates made by doctors often do not fit well with the patient’s oral cavity, and the drill sleeves are relatively rough. The degree is not high, and it affects the success rate of artificial dental implant surgery. Therefore, how to design a surgical guide that fits the inside of the patient's mouth is a technical pr...
