Abstract

The invention discloses a color-masking zirconia veneer. The color-masking zirconia veneer is prepared by the steps of carrying out color masking after micro-sculptures of a zirconia veneer are processed, and finally carrying out sand blasting or processing a flake zirconia film. According to the color-masking zirconia veneer, micron-scale sculptures are prepared on the surface without mechanically damaging the material, and a porous flake surface from a nano scale to a micron scale is obtained by virtue of repeated film plating techniques before and after sintering, so that a mechanical interlocking structure between the specific surface area of the zirconia veneer and an adhesive, the adhesion bonding between the zirconia veneer and a natural tooth is enhanced, and the zirconia veneer can meet the clinical requirements on the adhesive property. The color-masking zirconia veneer has the beneficial effects that a color-masking function is considered, meanwhile, the strength of the zirconia veneer is guaranteed, and a very good aesthetic repairing effect is achieved.

Description

technical field

[0001] The invention relates to the technical field of making dental ceramic materials, in particular to a color-shielding zirconia veneer. Background technique

[0002] Veneers are a widely used product in clinical aesthetic restoration. Porcelain restoration materials have been used in clinical practice for 100 years. At present, all-ceramic veneer materials with more clinical applications can be divided into leucite-based all-ceramic, Lithium disilicate-based all-ceramic, alumina-based all-ceramic, zirconia-based all-ceramic and other systems; can be divided into feldspar and non-feldspar according to clinical treatment methods, and can be divided into powder slurry coating according to different production processes Plastic, cast porcelain and cutting ceramics. The strength of alumina porcelain powder sintered veneer and zirconia porcelain block cutting veneer is better than that of silicate cast porcelain veneer, but compared with the translucency of ca...
