| Outline of Final Research Achievements |
Ultraviolet photo functionalization is a new method for improving the surface characteristics of titanium implants. The purpose of this study was to examine the effect of photo functionalization on morphological analysis. The implant on one side was photo functionalized with UV light (UV group). The implant on the other side was served as the control group (control group). Resin cast specimens were examined by SEM.
In the control group, peri-implant bone was not observed clearly along the implant surface. Instead of bone, In the photo functionalization group, peri-implant bone was thicker than the control group. Blood vessels were buried under newly formed bone tissue. Bone trabeculae are attached to the thick peri-implant bone.The photo functionalization of implants using the photocatalytic activity of titanium improved the bone-binding strength of implants.
