Problems solved by technology

[0003] Although there are many dyeing solutions for zirconia pre-fired dentures used in all-ceramic dentures on the market, there are generally defects such as long dyeing time, complex components, and high cost, and the existing Vita 16-color staining solutions cannot meet the requirements. In view of the needs of daily production, it is necessary to invent a dyeing solution for all-ceramic dentures with short dyeing time, low cost and good dyeing effect.

Abstract

The invention relates to staining fluid for a zirconia pre-burned false tooth. The staining fluid consists of the following raw materials in parts by weight: 1000 parts of deionized water, 9.6 to 57 parts of iron chloride, 4.2 to 46.2 parts of erbium nitrate and 0.6 to 24 parts of praseodymium nitrate. The staining fluid has excellent permeation rate, the staining fluid can permeate for 0.8mm in 5 seconds in a single direction, for 1.2mm in 10 seconds in a single direction and for 1.5mm in 20 seconds in a single direction, the permeation speed is high, the stained pre-burned false tooth is integrally uniform in color; moreover, the light transmittance is similar to that of a natural color. Besides, the satisfaction on the requirement of vita 16 colors, four effect colors of A5, B5, C5 and G1 (gingival porcelain color) can also be achieved by the staining color, the production demand of a technician is satisfied, and the blank of the effect color in the industry can be filled. The staining fluid has the characteristics of short time, good staining effect and low cost, and is capable of completing the staining in ten seconds and suitable for the production of false tooth companies.

Description

technical field [0001] The invention relates to a dyeing solution, in particular to a dyeing solution for all-ceramic dentures, especially zirconia pre-fired dentures. Background technique [0002] Currently, in prosthodontics, color and light transmission are an important indicator affecting the objectivity of restorations and teeth. The use of dental CAD / CAM technology to make all-ceramic restorations has opened up a new way for the automatic processing of restorations and the production of high-strength all-ceramic crowns and bridges. The color of uncolored zirconia pre-fired dentures is mostly white to ivory. Although it can simulate the color of natural teeth to a certain extent, it cannot meet the clinical requirements for the color of restorations. Only by coloring zirconia and adjusting the color and light transmittance of zirconia to be close to the color and light transmittance of the tooth to be restored can the needs of customers be met. At present, the colorin...
