Abstract

The invention belongs to the technical field of material science and relates to staining fluid for zirconium oxide presintering false teeth. The staining fluid for the zirconium oxide presintering false teeth comprises the following components in parts by weight: 1000 parts of deionized water, 6 to 85 parts of nitrate coloring agent, 40 parts of penetrating agent and 5 parts of indicator. The staining fluid for the zirconium oxide presintering false teeth has high penetrating property and short staining penetrating time, is non-toxic and harmless, and is applied to staining of the zirconium oxide presintering false teeth according to the application method; the stained color has high uniformity and glossiness and is close to the color of natural teeth; the staining effect is stable and durable; and the permeability and the optical effect of the zirconium oxide material are not influenced.

Description

technical field [0001] The invention belongs to the technical field of material science and relates to a dyeing solution for zirconia pre-fired dentures and an application method thereof. Background technique [0002] With the popularization of CAD / CAM technology, zirconia materials are more and more widely used, especially in full zirconium dentures. Full zirconium dentures do not need veneering porcelain, and can be directly formed by CAD / CAM cutting. As long as the material thickness If the basic requirements are met, the hardness can fully meet the oral function. With people's continuous pursuit of dental aesthetics, the color of dentures has become one of the most important aspects of aesthetics. Zirconium oxide materials are divided into white zirconium and colored zirconium. White zirconium is a colored porcelain block ranging from white to ivory white. Colored zirconium is colored by directly adding colored oxides to the powder. In the process of processing zirconi...
