Zirconia Block is used for dental restorations, such as crown, bridge, inlay, veneer, using CAD/CAM or manual milling machines. The main ingredients of the product include zirconia, yttrium oxide, hafnium oxide, alumina and other oxides. Through the digital scanning of the tooth or tooth mold, the three-dimensional data of the tooth mold is obtained. According to the CAD design is carried out to design the porcelain block processing model. Then CNC machine tool was used to make CAM according to the porcelain block processing model, and the inner crown of all-porcelain denture was made by air sintering or vacuum sintering, so as to achieve the strength and aesthetic effect required by clinical use. Finally, the inner crown of the all-porcelain denture was glazed with porcelain powder to form the combination of porcelain, and the all-porcelain denture was made.
