Problems solved by technology

At present, after the metal-fused-to-metal crown is piled with plastic-shading porcelain, it is directly put into the porcelain furnace for sintering. After cooling, it is taken out and dentin porcelain is piled up with plastic, and then it is directly put into the porcelain furnace for sintering. The process of finished metal porcelain teeth, plastic opaque porcelain and dentin porcelain is to apply the paste of plastic opaque porcelain and dentin porcelain on the surface of the tooth; the surface of the finished metal porcelain tooth is often A large number of air bubbles are generated, resulting in rework by blasting porcelain, wasting manpower and materials

Abstract

The invention discloses a method for preparing metal-ceramic teeth: preparing metal-ceramic inner crowns; stacking plastic-shading porcelain on the surface of the inner crowns, drying and placing them in a porcelain furnace for vacuum sintering at 900-910°C to obtain One-time treatment of metal-ceramic teeth; for first-time treatment of metal-ceramic teeth, plastic dentin porcelain is dried and placed in a porcelain furnace for vacuum sintering at 925-935°C to obtain secondary-treatment metal-ceramic teeth; After the shape of the metal porcelain teeth is trimmed, the enamel porcelain is piled up on the surface and then dried after toning. The dried metal porcelain teeth are placed in a porcelain furnace and sintered at 900-910°C to obtain the metal porcelain teeth. ; It can prepare finished metal-ceramic teeth without air bubbles on the surface.

Description

technical field [0001] The invention belongs to the technical field of denture preparation, and relates to a method for preparing metal-ceramic teeth. Background technique [0002] With the continuous development of science and technology and the improvement of people's living standards, dental restoration materials have attracted more and more attention. Among them, metal-ceramic teeth are restorations made of low-melting porcelain and metal underlying materials, which combine the strength of metal and the beauty of porcelain. It is one of the most widely used restorations in dental fixed restorations today. The traditional preparation process of porcelain-fused-to-metal teeth is mainly as follows: making the inner crown → coating the inner crown with opaque porcelain and heat treatment → shape modification → sintering the ceramic outer crown → dyeing → obtaining the finished metal-ceramic tooth. At present, after the metal-fused-to-metal crown is piled with plastic-shadin...
