PROBLEM TO BE SOLVED: To provide a means for constructing an implant for medical or dental applications, whose surface composition is made of composite materials that enforce the safety of an implant and stimulate an osseous growth when surgically implanted in the bone. SOLUTION: An implant designed by this invention has an external surface and in vivo conformability of the core bodies composed of at least two different metal components or metal alloy components being in close contact with each other, and the mutually different metal or metal alloy component are expressed by the composite materials of a plurality of metal particles in a surface area of each square millimeters of the core body, so that EMF potential difference exceeding at least 25 mv, preferably 100 mv, per each core surface area of square millimeters develops between the first and second components. |
