Outline of Final Research Achievements

Dental implants have become modern option for dentists toreplace missing teeth, resulting in an increasing percentage of the adult population with implant supported prosthesis. However, they have still some serious problems. For example, peri-implantitis iswell-known as a destructive inflammatory disease throughinfectious of soft and hard tissuessurrounding dental implants. It causes bone loss around an osseointegrated implant with increasing risk of implant failure.Therefore, we developed experimental materials containing cetylpyridinium chloride (CPC) and phophopullulan to prevent and treat peri-implantitis. Microbiological examination revealed that Ti treated with the experimental materials showed excellent antibacterial effect. These results are useful to develop new commercially available antibacterial materials for prevention and treatment of peri-implantitis.
