Development of Metallic Materials with High Bone Tissue Compatibility
　Metals are clinically used for artificial joints and artificial tooth roots owing to their high strength and toughness. We attempt to provide the metals with bone-bonding ability by several surface modification techniques.

Titanium metals with high bone tissue compatibility.	Bone-bonding of surface-modified tantalum metal.
