Abstract
Titanium has widely been used as a biomaterial because of its excellent corrosion
resistance and biocompatibility. However, problems with respect to biological reaction and fitness of
elastic modulus for human bone or tooth have yet to be solved. Porous titanium is expected to be a
promising material to solve these problems. The aim of this study is to clarify the effect of the porous
structure of this material on the biomechanical compatibility. The spherical pure titanium powder,
with an average particle size of 100 µm, was sintered by spark plasma sintering. The sintered porous
titanium compacts had a porosity of 33 %. The specimens were machined from the sintered compacts
for the evaluation of the mechanical properties. The elastic modulus indicated a value close to human
bone, while the tensile and compressive strengths showed lower values than those of human bone.
