Abstract

The invention discloses baked porcelain powder for a zirconium-oxide all-ceramic crown. The baked porcelain powder comprises bonding porcelain powder, body porcelain powder and glaze porcelain powder. The bonding porcelain powder comprises, by weight, 90%-99.5% of basis bonding porcelain powder, 0.1%-5% of nanometer second phase A and 0.1%-5% of pigment A; the body porcelain powder comprises, by weight, 90%-99.5% of basis body porcelain powder, 0.1%-5% of nanometer second phase B and 0.1%-5% of pigment B. When the baked porcelain powder is sintered on the zirconium-oxide all-ceramic crown, an obtained ceramic substrate-baked porcelain compound is even in baked-porcelain-powder dispersion; after a ceramic substrate is sintered to porcelain, binding force between the porcelain and the ceramic substrate is high, the biocompatibility between the porcelain and the ceramic substrate is excellent, and wear resistance and corrosion resistance are good; meanwhile, in appearance, the baked porcelain powder has the advantages of being high in color accuracy, even in coloring, natural and lifelike in color and the like. Meanwhile, the invention further discloses a preparing method of the baked porcelain powder for the zirconium-oxide all-ceramic crown.

Description

technical field

[0001] The invention relates to a biological material and a preparation method thereof, in particular to a crown porcelain powder for denture processing and a preparation method thereof. Background technique

[0002] At present, the main components of zirconia all-ceramic crown porcelain powder produced at home and abroad are bonded porcelain, body porcelain and glazed porcelain. Corresponding color matching. The technology of domestic manufacturers in zirconia crown ceramic powder is immature, and the quality and aesthetics of the produced ceramic powder are not as good as those imported from home and abroad, and have not yet been recognized by denture processing factories and users.

[0003] Porcelain-fused-to-metal technology is a commonly used restoration method in clinical practice. At present, the commonly used metal materials for crowns mainly include precious metal alloys and base metal alloys. However, from the perspective of application, the price ...
