Outline of Final Research Achievements

Titanium has been used as a dental implant material and osteoblast is known to attach well to titanium with moderately rough surface. In contrast, gingival epithelial cell and fibroblast are known to attach well to titanium with turned surface. The aim of the present study is to elucidate the nature of tissue-implant interface and improve the tissue response toward implant, using both implant surface functionalization and host tissue activation. As a result, we could report that the distribution of proteins which localized at the bone-titanium interface changed over time, hydrothermal treatment of titanium with CaCl2 solution improved biocompatibility, and statins enhanced the wound healing of peri-implant tissue.
