Method for manufacturing dental implantation surgical guide plate

Abstract

The invention relates to a method for manufacturing a dental implantation surgical guide plate. The method comprises the following steps of: planning a dental implantation; obtaining a digital plaster model of an oral cavity; providing dental implantation planning data for the digital plaster model by using feature positioning; then integrating both the digital plaster model and the dental implantation planning data into digital processing data; fixing a model material block to a processing position so that the digital processing data guides a processing machine to process the model material block into a solid oral cavity model which has a shape in fit with that of an oral cavity of a patient and has structures such as teeth, gingiva and dental implantation positions; arranging auxiliary positioning pieces at the dental implantation positions; and finally molding the surgical guide plate provided with a plurality of guide holes on the solid oral cavity model by matching a thermoplastic material with a rollover molding method or a vacuum molding method, and thus, the more accurate surgical guide plate can be manufactured under the condition of time saving, labor saving and low manufacturing cost.

Description

technical field [0001] The invention relates to a method for manufacturing a guide plate, in particular to a method for manufacturing a guide plate for dental implant surgery. Background technique [0002] During the traditional artificial dental implant surgery, patients are prone to bleeding, swelling, pain and other phenomena. In order to avoid the occurrence of the above-mentioned phenomena, we have used accurate head computerized tomography scans and computer software diagnosis methods. It is already possible to see through the three-dimensional model of the skeleton and the direction of important nerves without surgery. At the same time, the dentist can evaluate the patient's bone environment and judge the quality of the teeth. Therefore, it is possible to simulate surgical implants on the computer. Artificial implants are inserted to ensure that important nerves and blood vessels are avoided during dental implant surgery, which greatly improves the safety of the opera...

Problems solved by technology

Since the implant planning is completed based on 3D digital images, most of the data are virtual drawing data or digital data, which are difficult to accurately present on the guide plate 11, and can only be made more accurate and correct after repeated scanning and correction. The guide plate 11 makes the guide plate 11 made by the existing manufacturing method less accurate, and has the defects of relatively poor manufacturing efficiency and high manufacturing cost

[0011] This shows that above-mentioned existing guide plate manufacture method obviously still has inconvenience and defect in method and use, and needs to be further improved urgently

In order to solve the above-mentioned problems, the relevant manufacturers have tried their best to find a solution, but no suitable design has been developed for a long time, and the general method has no suitable method to solve the above-mentioned problems. This is obviously related. The problem that the industry is eager to solve
