ABSTRACT:
Ceramic composite comprising a porous ceramic body having directly fitted thereon a dense ceramic body, the composite is produced by a process which comprises the steps of: separately producing the porous ceramic body and the dense ceramic body, inserting a projecting portion of the dense body into a bore portion of the porous body, and simultaneously sintering both the dense and porous bodies at a sintering temperature. The ceramic composite has excellent properties such as heat resistance, resistance to thermal cycle, water resistance and in vivo compatibility, and therefore is particularly useful as an implant material such as an artificial tooth root, an artificial bone and a percutaneous device.
