Problems solved by technology

[0003] However, it is found that zirconia ceramics, as the most rational dental restoration material, still have significant defects in practical applications: First, if the abutment is dark in color or a metal abutment is planted during use, the zirconia all-ceramic crown will show through. The color of the abutment teeth or the black color of the metal abutment will cause a large difference in color with the adjacent teeth, and the effect of natural simulation cannot be presented; secondly, the method of dyeing dental zirconia ceramics in the prior art is complicated and the raw materials Complex composition and high cost of raw materials

Abstract

The invention discloses a masking liquid for a dental zirconium oxide ceramic. The masking liquid comprises a masking agent, a color indicating agent, an additive and deionized water. The masking liquid can reduce the transparency in a tooth restoration without affecting the color effect out of the restoration. Meanwhile, the invention also discloses a preparation method of the masking liquid forthe dental zirconium oxide ceramic. The preparation method has the obvious advantages of simple process, low manufacturing cost and good repeatability. Moreover, the invention also discloses application and an application method of the masking liquid for the dental zirconium oxide ceramic. The problem that the transparency in the dental zirconium oxide ceramic is too high can be improved obviously, so that the finally obtained tooth restoration can obtain a natural emulational effect.

Description

technical field [0001] The invention relates to the technical field of dental ceramics, in particular to a color-masking liquid for dental zirconia ceramics and a preparation method and application thereof. Background technique [0002] At present, dental ceramics refer to glass ceramic materials and products used for dental treatment and restoration, which belong to the category of medical devices. Zirconia ceramics have excellent mechanical properties, its bending strength exceeds 1000MPa, and a relatively thin thickness can achieve high strength, so it is an ideal dental restoration material. In dental restorative treatment, the restoration should not only have certain strength, wear resistance, corrosion resistance and biocompatibility, but also have good aesthetic properties. Especially in recent years, with the improvement of national living standards, patients have higher and higher requirements for the similarity between dental restorations and natural teeth in appe...
