| Outline of Final Research Achievements |
We aimed to develop a zirconium (Ce-TZP) implant fixture functionalized by ultraviolet (UV). Ce-TZP/Al2O3 treated with hydrofluoric acid (HF) irradiated by UV with shifting the wavelength and the irradiation time. The adhesion, proliferation, differentiation, and expression of bone related genes of osteoblastic cell (MC3T3-E1) on these samples enhanced by 15-40% under the wavelength and time of a specific pattern. Similarly, osseointegration capability on UV functionalized Ce-TZP increased significantly compared to control group. Oxidant stress induced cell cytotoxicity by UV irradiation did not show deleterious effect on cellular level. We concluded about this matter that there is no our safety concern.
