Ultra smooth ceramic materials are prepared by the low temperature sintering of a ceramic body that has been infiltrated prior to sintering with an inorganic polymer. The infiltration allows for a decrease in the sintering temperature which translates into a smoother, stronger ceramic material.

Low temperature sintering of ceramic materials

An improved method for producing endosseous implants by thermally spraying a ceramic material onto the surface of a metallic core material having a rough surface, i.e. a maximum surface roughness of 15 to 100 .mu.m, which can produce implants which have excellent characteristics in regard to the metallic material and ceramic material and do not dissolve out harmful metal ions. The endosseous implants are useful for implantation in various bones including tooth roots and joints in living bodies.
