Problems solved by technology

However, this method increases the preparation of PE film, printing and coloring and heat treatment, making the whole process quite complicated.
At the same time, literature searches at home and abroad show that there are very few research reports on the infiltration coloring technology of all-ceramic teeth.

Abstract

The invention discloses a dyeing solution for dental zirconia ceramics, which consists of a colorant, a dispersant, a complexing agent, a thixotropic agent and a color indicator. In the present invention, by adding a color indicator in the dyeing liquid, the dyeing liquid can display different colors before sintering, and the dyeing time can be adjusted according to the depth of the color, so as to prevent blind dyeing; The shortcomings of blindness and experience in the tooth penetration coloring process have the advantages of short dyeing penetration time, strong stability, and high quality rate of all-ceramic tooth products; the production and use methods of the dyeing solution of the present invention are simple, the source of raw materials is wide, and the cost is low. Low is suitable for large-scale industrial production.

Description

technical field [0001] The invention relates to the technical field of material science, in particular to a dyeing solution for dental zirconia ceramics. Background technique [0002] At present, the technology of making all-ceramic restorations with dental CAD / CAM technology is quite mature, which can fully realize the automatic processing and the production of high-strength all-ceramic crowns and bridges. As the most important dental all-ceramic crown material, zirconia is characterized by its white to ivory color after sintering. Although it has a certain degree of translucency, it cannot meet the clinical requirements for the color of the restoration. In order to meet the color requirements of clinical dentures, it is often necessary to shade the all-ceramic base crown to lose part of its transparency. By adjusting the transparency, color and saturation of zirconia itself, it is consistent with the tooth to be restored. The denture after staining can save the preparatio...
