| Outline of Final Research Achievements |
A method of coating commercially pure titanium (cpTi) implants with a highly crystalline, thin hydroxyapatite (HA) layer using discharge anodic oxidation followed by hydrothermal treatment (functionally graded nanohybrid titanium dental implant; NanoTi) has been reported for use in clinical dentistry. We reported that a thin HA layer with high crystallinity and nanostructured anodic titanium oxide film on such NanoTi implant surfaces might be a crucial function of their surface-specific potential energy. The cellular gene expression responses driving extracellular and intracellular molecular interactions thus play an important role in maintenance at the interface between NanoTi implant surfaces and the mesenchymal stem cells (MSCs). These data indicated that the change of physicochemical properties of NanoTi surface may play a key role in the phenomenon of homing mechanism of MSCs and osteoconduction during the process of osseointegration.
