Problems solved by technology

[0005] The manufacturing method of the all-enveloping ultra-thin porcelain veneer disclosed in this patent document, although the prepared porcelain veneer has strong compression resistance, fits the teeth, and is not easy to collapse, but it needs to grind away a lot of tooth tissue. The color of the side repair is not good, which affects the aesthetic effect

Abstract

The invention discloses a dental mixed porcelain laminate veneer and belongs to the technical field of dental medical instruments. The dental mixed porcelain laminate veneer is characterized by comprising a tongue side porcelain laminate veneer and a lip side porcelain laminate veneer which cover a tooth body; the tongue side porcelain laminate veneer completely covers the tongue side of the toothbody; the lip side porcelain laminate veneer partially covers the lip side of the tooth body; a boundary line for butt joint and combination is formed between the tongue side porcelain laminate veneer and the lip side porcelain laminate veneer; the boundary line is positioned at the rear cutting end of the tongue side porcelain laminate veneer and avoids for 2mm from an occlusion contact area toform a shoulder of a round right angle or is positioned at 1 / 2 of the tooth body in an incisal edge lip and tongue direction; the tongue side porcelain laminate veneer is made of zirconium oxide or glass ceramic; and the lip side porcelain laminate veneer is made of feldspathic ceramic. The dental mixed porcelain laminate veneer disclosed by the invention has both mechanical and aesthetical properties, is applicable to occlusion reconstruction for a tooth with an occlusion space on the lip side and normal tongue colors and fixing and repairing of a tooth with the occlusion space on the lip side, and is good in practicability, in addition, more tooth body tissue can be maintained, tooth preparation on the tongue side is not needed, and the tooth preparation amount on the lip side is smallerthan 0.5mm or is not needed.

Description

technical field [0001] The invention relates to the technical field of dental medical instruments, in particular to a dental hybrid porcelain veneer and a manufacturing method thereof. Background technique [0002] Porcelain veneer is a fixed restoration, which is mostly used for patients with tooth surface defects, staining, discoloration, enamel dysplasia, tetracycline teeth, dental fluorosis, deformed teeth, excessive interdental spaces, proximal caries and incisal defects, etc. , using a relatively less molar restoration method, the porcelain restoration material is bonded to the tooth surface to restore the normal shape of the tooth and improve its color. [0003] In the prior art, usually the labial side of the tooth is fully covered with porcelain veneers, and the lingual side of the tooth is partially covered with porcelain veneers, and both the labial and lingual sides of the teeth are made of the same material. Porcelain veneers are divided into two types accordin...
