| Outline of Final Research Achievements |
We developed a novel and simple surface treatment process for forming thin hydroxyapatite coating of nanometer thickness on titanium. In the present research, optimization of the treatment parameters was performed, and thereafter, biocompatibility of the treated titanium was evaluated, in order to complete this process. The coating using optimum condition consisted of hydroxyapatite with excellent bonding strength, and its thickness was ca. 300 nm. Furthermore, the cell tests demonstrated that the treated-titanium has sufficient biosafety similar to an untreated surface and can activate a bone-formation of osteoblast.
