Metal ceramic repairing body inner crown and preparation method thereof

Abstract

The invention discloses a metal ceramic repairing body inner crown. A TiN metal film coats the surface of a titanium alloy root crown in a sputtering mode, and the TiN metal film is a yellow film, so that silver or grey white metal color of titanium alloy metal is covered, the metal color can be prevented from being exposed in the using process of a titanium alloy ceramic tooth, and the attractiveness of the ceramic tooth can be improved; in addition, the TiN metal film covers the surface of the titanium alloy root crown, so that the titanium alloy root crown is protected, finally, the TiN metal film can reduce the surface stress of the surface of the titanium alloy root crown, and the problem of crackling in the later-stage ceramic preparation process of the titanium alloy root crown can be avoided.

Description

technical field

[0001] The invention relates to the technical field of metal porcelain, in particular to a metal porcelain restoration crown and a preparation method thereof. Background technique

[0002] Tooth or dentition loss and defect are common and frequently-occurring diseases in humans. Tooth or dentition loss or defect affects people's chewing, pronunciation and other functions, as well as their appearance. With the development of society and the improvement of people's living standards , People are now paying more and more attention to the style and quality of dentures. Metal-ceramic restorations are made by applying dental ceramic materials on the surface of metal or alloy substrates and sintering under vacuum conditions. They are ideal permanent restorations for tooth or dentition loss or defect, and are widely used in the field of oral restoration.
