METHOD FOR PREPARING MATERIAL FOR DENTAL RESTORATION AND MATERIAL FOR DENTAL RESTORATION PREPARED BY THE SAME

摘要

PURPOSE: A method for manufacturing a dental restorative composite is provided to control teeth color and improve hardness property. CONSTITUTION: A dental restorative composite is manufactured by adding MgO, ZrO2, Y2O3 or TiO2 compound to a ceramic dental restorative composite, and sintering. The redness is controlled by increasing and decreasing the content of MgO. The yellowness is controlled by increasing and decreasing the content of TiO2. The MgO, ZrO2, Y2O3 or TiO2 is contained as an additive. The additive is sintering aid.
