Abstract

The invention discloses a preparation technology for porcelain teeth, and relates to the technical field of dental restoration. The preparation technology is technically characterized by comprising the steps of manufacturing a metal inner crown, carrying out sand blasting on the surface, carrying out heat treatment, carrying out surface cleaning, and sintering a ceramic outer crown so as to obtaina finished product of the porcelain tooth. According to the preparation technology, through a mode that the metal inner crown is subjected to sand blasting treatment and then is subjected to heat treatment, a metal oxide film is formed on the surface of the metal inner crown, so that the bonding strength between the ceramic outer crown and the metal oxide film is improved, and therefore the probability that the porcelain teeth are fractured is lowered.

Description

technical field

[0001] The invention relates to the technical field of tooth restoration, in particular to a preparation process of porcelain-fused-to-metal 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, porcelain 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 fixed oral restorations today.

[0003] The traditional preparation process of porcelain teeth mainly includes: making metal inner crown→heat treatment of metal inner crown→sandblasting surface→ultrasonic cleaning or steam cleaning→sintering ceramic outer crown→obtaining finished porcelain tooth.

[0004] When the above-mentioned preparation process sinters the ceramic outer crown, the cerami...
