A kind of dental implant manufacturing method

Abstract

The invention provides a manufacturing method of an implant tooth. The manufacturing method comprises the following steps of (1) manufacturing a wax model of a tooth crown, wherein the tooth crown comprises a groove-shaped neighboring area; (2) inlaying an inlay crown into the neighboring area; (3) inserting a casting passage into the wax model, placing a casting gold ball on the casting passage,and placing the wax model on a casting ring; (4) injecting the embedding material, roasting the casting ring after the embedding material is completely tightened, completely melting and volatizing thewax model, and forming a casting cavity in the embeddind material; (5) melting the alloy, and injecting into the casting cavity by utilizing the centrifugal force; (6) after the alloy is cooled, removing the residual material on the embedding material and the casting part; (7) coating a thin layer of opaque ceramic onto the surface of the base crown by a professional writing brush, sintering, andcooling; (8) filling the inlay crown. The manufacturing method of the implant tooth has the advantages that the produced implant tooth has high precision, and can be repeatedly used; the blockage offoods can be quickly, simply and conveniently solved, and the prosthesis is not destroyed.

Description

technical field [0001] The invention relates to a dental implant manufacturing method, which belongs to the technical field of dental implant manufacturing. Background technique [0002] For dental implants, due to the displacement of natural teeth over time, loosening or defect caused by periodontitis, gaps will gradually appear on the adjacent surface, which can easily lead to food impaction. Food impaction is considered to be the most common problem after fixed tooth restoration. One of the complications. Long-term food impaction can easily cause damage to the tooth body and periodontal tissue, as well as peri-implantitis and alveolar bone resorption, which will adversely affect the long-term stability and aesthetics of the implant, reduce the patient's chewing comfort, and affect the quality of life . The existing porcelain implant restoration design, if the natural teeth are displaced, the screw-retained ones can be disassembled, but it needs to be re-taken and sent t...

AI Technical Summary

Problems solved by technology

Clinically, food impaction will occur repeatedly as the patient's chewing time increases, and the repeated disassembly and reconstruction of the restoration will increase the cost of the patient and bring hidden dangers to the doctor-patient relationship
