In this article are shown good and negative properties of oxide zirconia, based on literature data, are demonstrated advantages of oxide alumina for fabrication of full ceramic dental prostheses. By the author collective is made the study of mechanical properties of ceramic material for prosthetic constructions, based on oxide alumina, obtained by the plasma spraying method, developed by «Uralintech» company and the author collective of USMU. For the method of producing a ceramic material based on alumina is formed an application for getting the patent for an invention As a result of comparative analysis of the mechanical properties in compression and three-point bending of the samples of ceramics based on alumina, obtained by plasma spraying, depending on the annealing temperature proved that this material may be used in prosthetic dentistry for the manufacture of ceramic structures. Studies have shown that the optimum annealing temperature of the aluminum oxide is 1200 °.
