Abstract: Disclosed are a zirconia-based antibacterial denture material and a preparation method thereof. The zirconia-based antibacterial denture material includes components with the following mass parts: 75 to 80 parts of zirconium oxide, 2 to 5 parts of nanosized silver oxide, 3 to 5 parts of nanosized zinc oxide, 1 to 3 parts of nanosized lanthanum oxide, 1 to 3 parts of nanosized yttrium oxide, 1 to 2 parts of cerium oxide, and 1 to 2 parts of size control agent. The zirconia-based antibacterial denture material has good antibacterial effect and high strength.

Abstract: Disclosed are a glass ceramic composition, a preparation method and application thereof. The glass ceramic composition according to the present application includes: 58% to 72% of SiO2; 0% to 4% of Al2O3; 0% to 5% of Na2O; 3% to 8% of K2O; 8% to 17% of Li2O; 2.5% to 5% of P2O5, 0% to 2% of MgO, 0% to 2.5% of B2O3; 0% to 5% of ZnO; and 0% to 3% of ZrO2. It is possible to prepare such lithium metasilicate glass ceramic with a crystal phase of lithium metasilicate, a crystallinity of greater than 50%, a grain size of 30 nm to 60 nm and a hardness of 500 kgf/mm2 to 590 kgf/mm2. The composition does not require an introduction of a high proportion of zirconia content, and can be ground to a thickness of 0.2 mm without edge collapse.
