Dyeing liquor for dental ceramics
The invention provides dyeing liquor for dental ceramics. The dyeing liquor for dental ceramics comprises a solvent, a coloring agent and an organic addition agent. Compared with the conventional dyeing liquor in the prior art, the dyeing liquor for dental ceramics, provided by the invention, has the characteristics as follows: (1), the dyeing liquor self needs to be stabilized, is harmless to human bodies or causes less damage; (2), the depth of penetration of the dyeing liquor to dental ceramics needs to be sufficient, and the depth of dyeing penetration to pre-sintering green bodies needs to be greater than 5mm; (3), the dyeing liquor needs to be uniform in dyeing the dental ceramics in the surface or in the direction perpendicular to the surface, that is, the dental ceramics, after being subjected to localized grinding or finishing at different parts with different grinding amounts, can still be uniform in color; (4), at the same time, inorganic ions are added to the dyeing liquor, so that an optical effect of the dental ceramics is obviously improved, and a sense of quality similar to that of natural teeth is achieved.
