Embodiment Construction
[0031] like figure 1 Shown is the structural diagram of the dental implant of the present invention, including the crown body 1 and the groove 2 provided on the crown body 1, the groove 2 can be filled with inlays or filling materials, if there is food impaction, take out the original Some inlays and new inlays are placed; or the filled filling material is removed and the filling material is refilled. Dental implants can be reused, which can quickly and easily solve the problem of food impaction without destroying the restoration.
[0032] like figure 2 As shown, the present invention provides a kind of dental implant manufacturing method, comprises the following steps:
[0033] (1) Select the appropriate abutment and make fine adjustments;
[0034] The selection of a suitable abutment includes: if the implant is shifted horizontally when the impression is taken, after filling the mold, the appropriate abutment is selected according to the diameter of the implant, the heigh...

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...
