티타늄 및 티타늄 합금은 우수한 기계적 성질과 생체적합성, 그리고 골유착(osseointegration) 특성으로 인해 치과와 정형외과의 임플란트 재료로서 성공적으로 이용되고 있으며, 임상적으로도 높은 성공률을 나타내고 있다1). 또한 최근에는 골유착을 촉진시키기 위하여 임플란트 표면에 조골세포(osteoblast)의초기 부착을 증진시키기 위한 다양한 표면처리들이 연구, 개발되고 있다2~4). 하지만 임플란트 사용이 증가함에 따라 이에 따른 감염으로 인한 임플란트 실패 역시 증가하고 있으며, 이러한 실패를 줄이기 위하여 현재 임플란트의 항균능력을 증진시키려는 연구들이 진행되고 있다5~7). 따라서 이번 연구에서는 티타늄 임플란트의 항균코팅의 동향에 대해서 살펴보고 각각의 특징들을 설명하고자 한다.
Titanium and titanium alloys are the most common materials used for dental and biomedical implants, owing to their biocompatibility and favourable mechanical properties. However infection of the region surrounding a dental implant by pathogenic microorganisms is a significant factor in implant failure. Prevention and control of microbial colonization of implant surfaces is considerable interest to the biomedical community. One important strategy is to render the implant surface antibacterial by impeding the formation of biofilm. A number of approaches have been proposed for this purpose. Therefore, we reviewed the researches of antibacterial coatings on titanium implants in this articles.
