Research Abstract

The aim of this study is to establish a novel technology to achieve efficient bone regeneration by controlled release of bioactive factors from titanium implants. We designed a titanium implant chamber which contains a biodegradable material releasing bioactive factor (b-FGF). We found that this system induces bone regeneration around the implant in an animal model. We also identified osteogenesis inducible peptide and small molecule, and elucidated mechanisms of these molecules on bone regeneration.
