Abstract

Biocompatible porous titanium could be used for surgical implants like bones, joint prostheses or dental roots due to its excellent biocompatibility and osteoconductivity. Porous structure permits ingrowth of bone tissue, transportation of body fluid and nutrients. Mechanical property like elastic modulus and compressive strength depends on the pore characteristics like porosity, pore size, pore morphology of the porous titanium fabricated by different methods. The tailored elastic modulus of porous titanium matches that of cancellous bones. Deposition of hydroxyapatite coating on the surface of porous titanium can improve its bioactivity and biocompatibility. The fabrication method, surface modification, in vitro and in vivo studies and future research directions of porous titanium are reviewed in this literature..
