Abstract

The invention relates to a method for using zirconia to sinter full-ceramic tooth, which uses zirconia powder to be sintered at 1500-1900Deg. C to obtain the zirconia ceramic powder, to be grinded into powder or pulp, then adds some sintering agent and flexibilizer, to be sintered in mold secondary to obtain the full-ceramic tooth. The invention has simple process, less contraction, high strength, and low cost as 2% of foreign product.

Description

technical field

[0001] The invention relates to a dental prosthesis and a manufacturing method thereof, in particular to a dental prosthesis, which is especially suitable for restoration of all-ceramic crowns, all-ceramic studs and all-ceramic inlays. Background technique

[0002] Over the past 100 years since the advent of all-ceramics, there have been die-cast ceramics, glass ceramics, alumina ceramics, etc., and zirconia ceramics have the highest flexural strength, which is also a hot spot in the international dental market today.

[0003] Dental restorations include metal porcelain and all-ceramic. Due to the opacity of metal crowns, the optical properties cannot satisfy patients and dentists in pursuit of the aesthetic effect of natural teeth. Metal allergies, red and swollen gums, and blue gums have appeared in metal porcelain all over the world. Too much metal in the mouth can also produce electromagnetic effects. Now developed countries have increased the production...
