  • Implant with bioactive particles stuck and method of manufacturing the same
    Publication number: 20020143404
    Abstract: An implant includes a main body member having bio-compatibility, and particles formed of bioactive material and dispersedly provided at the surface of an embedded section of the main body member. Each of the particles has a part embedded in the embedded portion and the other part protruding from the embedded portion. The main body member is formed of titanium or titanium alloy. The particles having osteo-conduction are formed of a material selected from among a group consisting of sintered substances of hydroxylapatite, &agr;-tricalcium phosphate, &bgr;-tricalcium phosphate, tetra-calcium phosphate, a single substance of amorphous calcium phosphate, monetite, brushite, 45S4 glass, and a mixture of them. It is desirable that the embedded section surface has a surface roughness in a range of 5 to 50 &mgr;m.

    Patent number: 5934287
    Abstract: An implant includes a main body member having bio-compatibility, and particles formed of bioactive material and dispersedly provided at the surface of an embedded section of the main body member. Each of the particles has a part embedded in the embedded portion and the other part protruding from the embedded portion. The main body member is formed of titanium or titanium alloy. The particles having osteo-conduction are formed of a material selected from among a group consisting of sintered substances of hydroxylapatite, .alpha.-tricalcium phosphate, .beta.-tricalcium phosphate, tetra-calcium phosphate, a single substance of amorphous calcium phosphate, monetite, brushite, 45S4 glass, and a mixture of them. It is desirable that the embedded section surface has a surface roughness in a range of 5 to 50 .mu.m.
