AbstractPorous titanium and its alloys are attractive for orthopedic/dental implant applications because of their good biocompatibility and tailorable mechanical properties. This paper reviews recent advances in the development of porous titanium materials, including fabrication techniques for metal forms, powder-metallurgy methods for producing porous titanium structures, mechanical properties, and modeling of elastic behaviors by analytical methods. For orthopedic implant applications, porous titanium materials with Young's modulus close to that of cortical and cancellous bones can be fabricated by the adjustment of porosity and processing parameters. However, the overal mechanical performance of the porous titanium is not yet fully satisfactory for most load-bearing implants and further improvements in mechanical properties are needed.
