SURFACE MODIFICATION OF PURE TITANIUM BY HYDROXYAPATITE IMPLANTATION

Abstract

Fixation of orthopedic titanium implants to living bone is one of keys to achieve a successful result but still developing. Enhancement of bone formation around the implants can make a contribution to long-term stable fixation. In this study, spherical HAP ceramics (φ400-500μm) were implanted in the surface of cylinder shape pure titanium by the loading up to 1 kN at 1173 K to enhance bone formation around the implant. By this method, the spherical HAP ceramics were mechanically held on the surface of the pure titanium.
