Recent Progress in Mechanically Biocompatible Titanium-Based Materials

Mechanical and biological biocompatibility is important consideration for materials that are used as metallic implants. During the past two decades, many ß-type titanium alloys composed of non-toxic and hypoallergenic elements with low Young’s moduli have been developed worldwide. Recently, the development of new titanium-based materials to improve the mechanical and biological biocompatibility of metallic implants has progressed under advanced concepts. This chapter focuses on the improvement of mechanical biocompatibility, and recent research topics on such material developments are reviewed.
