Surface-Dependent Osteoblasts Response to TiO Nanotubes of Different Crystallinity.

One of the major challenges of implantology is to design nanoscale modifications of titanium implant surfaces inducing osseointegration. The aim of this study was to investigate the behavior of rat osteoblasts cultured on anodized TiO nanotubes of different crystallinity (amorphous and anatase phase) up to 24 days. TiO nanotubes were fabricated on VT1-0 titanium foil via a two-step anodization at 20 V using NHF as an electrolyte.
