ABSTRACT:
An improved implant for a bone, a joint and tooth root comprising a metallic base material and a coating layer of hydroxyapatite which is formed by thermally sprayed hydroxyapatite powder or a mixture of hydroxyapatite powder and ceramic powder around the outer surface of the metallic base material, optionally a layer of a bonding agent and further a layer of ceramics are formed between the metallic base material and the layer of hydroxyapatite. The implant has a sufficient mechanical strength (e.g. impact strength) and further a good affinity to tissues of living bodies and is useful for implantation in various bones including tooth roots in living bodies.
