CERAMIC BLOCK FOR TOOTH RESTORATION AND MANUFACTURING METHOD OF THE SAME

摘要

PURPOSE: A method for manufacturing a ceramic dental restoration material is provided to suppress sensitive teeth and to teeth abrasion. CONSTITUTION: A dental restoration material contains 50-80 wt% of P_2O_5, 8-30 wt% of CaCO_3, 3-18 wt% of Al_2O_3, 0.01-5 wt5 of Li_2CO_3, 0.01-7 wt% of TiO_2, 0.01-5 wt% of ZrO, 0.001-2 wt% of SiO_2, 0.001-2 wt% of NiO, and 0.0001-1.5 wt% of Fe_2O_3. A method for manufacturing the dental restoration material comprises: a step of weighing the ingredients; a step of mixing the ingredients and pulverizing the ingredients; a step of performing the pulverized ingredients by thermal treatment; and a step of quickly cooling the resultant.
