Fabrication method for ceramic core of a dental prosthesis

摘要

An improved method for simplifying a slip casting applied conventional all ceramic core molding process by molding an all ceramic core from a ceramic sheet. In the method, there is prepared a slurry which consists mainly of alumina, spinel, alumina/zirconia powder, by adding thereto a dispersant, a binding agent, a plasticizer, a solvent and the like. The slurry is formed into a sheet having a thickness of 0.1mm to 1.0mm for thereby fabricating a tooth molding mass by using a heat hydrostatic pressing at a pressure of 15 Kgf/cm<2> to 150 Kgf/cm<2> at a temperature of 50 DEG C to 110 DEG C, with slurry composition for fabricating an all ceramic jacket crown applicable to an artificial crown comprises.
