Outline of Final Research Achievements

The dental peri-implantitis is caused by adhesion of dental biofilm to the open surface of pure titanium. The purpose of this study is to establish a highly durable DLC film on the surface of the implant on the surface around the gingival margin, and innovative dental implant that is compatible with alveolar bone attachment and deterrence of biofilm adhesion such as dual-phase surface conditions of the biocompatible and anti-biofilm.
As a result of depositing GCIB-DLC on the surface of pure titanium sample, it was confirmed that an adhesion strength of the DLC to the pure titanium surface is significantly high in comparison with a standard DLC coat. It could be applied to biofilm adhesion preventing type implants. In addition, GCIB-DLC showed an inhibitory effect on biofilm adhesion. We are going to examine biocompatibility and the safety by the animal test.
