306 Fabrication of Artificial Thighbone by Injection Molding of Mixture of Pure Titanium and Crystalline Hydroxyapatite Powder

Abstract

An artificial thighbone was fabricated by injection molding of mixed powders of hydroxyapatite suiting human body and pure titanium, followed by sintering the injected mold. Crystalline hydroxyapatite is a component which can rapidly bind with cells of human thighbone. The ability in the formation of apatite layer surrounding the apatite nucleation in simulated body fluid was investigated for various combinations of the ratio of titanium powders to hydroxyapatite powders.
