TiO2 nanotubes for bone regeneration

Nanostructured materials are believed to play a fundamental role in orthopedic research because bone itself has a structural hierarchy at the first level in the nanometer regime. Here, we report on titanium oxide (TiO2) surface nanostructures utilized for orthopedic implant considerations. Specifically, the effects of TiO2 nanotube surfaces for bone regeneration will be discussed. This unique 3D tube shaped nanostructure created by electrochemical anodization has profound effects on osteogenic cells and is stimulating new avenues for orthopedic material surface designs. There is a growing body of data elucidating the benefits of using TiO2 nanotubes for enhanced orthopedic implant surfaces. The current trends discussed within foreshadow the great potential of TiO2 nanotubes for clinical use.
