9.1 Introduction
Among all metallic biomaterials, Ti and its alloys are most widely
used because of their great strength, low density, high corrosion
resistance, and good biocompatibility [45, 69, 78]. However, the
problem for dental as well as orthopedic implant applications is the
mismatch of Young's modulus between the bone (10-30 GPa) and
metallic part (110 GPa for Ti) [24, 65]. This mismatch may result in
the formation of stress and retard the bone healing, which results
in increased bone porosity and failure of the implants. One way to
reduce Young's modulus of the metallic materials is to introduce
the pores [64, 101], minimizing tissue damage, and extended
implant life time. Pores introduced into the implant improve its
