Summary form only given. Biological integration of implant to surrounding tissue is important process as it determines its clinical success and attraction of bone cells. Also, in order to reduce the problems of implant-related infections, many kinds of the surface treatment on titanium have been proposed. The formations of TiO 2 nanotubes on the titanium have been widely studied to improve the biocompatibility of the surface, and silver nanoparticles have been known to exhibit the antibacterial efficacy. The purpose of this study was to carry out surface treatment on titanium and observe response of human periodontal ligament (hPDL) cells using combination of nanotube formation and silver nanoparticles treatment.

Summary form only given. Silver-containing titanium oxide (Ag-TiOx) nanocomposite thin films were deposited on cp-Ti substrate using DC reactive magnetron sputtering system. After deposition, heat treatment process was performed under 600°C for 1 hour. It is well known fact that the success of dental implant surgery is dependent on the bone-implant osseointegration. Also, longterm success rate is dependent on the absence of bacteria surrounding the implants which can induce the bio-film formation. In this study, effect of heat treatment on osseointegration and mechanical behavior of the antibacterial sputtered films was investigated.
