<p>PURPOSE:To provide an in-bone implant: with large adherent strength between the cover layer consisting of Ti or Ti-oxide formed on the surface of the in-bone implant and the core member; the new bone tissue can easily increase and penetrate the cover layer; with no harm on the bone when the implant is buried: and with no reduced effect of thermal spraying when the covering is formed. CONSTITUTION:An in-bone implant consists of a core member 1 with roughed surface and a cover layer composed of Ti or Ti-oxide, and the maximum surface roughness of the core member 1 is to be 20-40mum and that of the cover layer 2 is to be 30-50mum.</p> |
