摘要:
A method of bonding a high-strength zirconia post serving as a core in a glass-ceramic block, a method of bonding a metal link fastened with an implant fixture to the zirconia post, and glass-ceramic bondable to the zirconia post and a preparation method thereof, when preparing artificial teeth through a CAD/CAM processing method by using the glass-ceramic block as an artificial-teeth material. The lithium disilicate glass-ceramics containing cristobalite crystalline includes glass-ceramics composition including 10 to 15 wt % Li2O, 68 to 76 wt % SiO2, 2 to 5 wt % P2O5 working as a nuclei formation agent, 0 to 5 wt % Al2O3 to increase glass transition temperature and softening temperature and increase chemical durability of the glass, 2 to 3 wt % ZrO2, 0.5 to 3 wt % CaO for enhancing a thermal expansion coefficient of the glass, 0.5 to 5 wt % Na2O, 0.5 to 5 wt % K2O, and 1 to 2 wt % colorants, and 0 to 2.0 wt % mixture of MgO, ZnO, F, and La2O3.
