| Research Abstract |
Aiming to develop dental titanium alloys with antibacterial property and biocompatibility, we prepared experimental Ti-Ag alloys and investigated their properties. The Ti-Ag alloys inhibited biofilm formation, but did not have bactericidal activity. Calcium phosphates were spontaneously formed on the Ti-Ag alloys in a simulated body fluid. The Ti-Ag alloys had excellent corrosion resistance similar to that of titanium. It was suggested that the Ti-Ag alloys were a new type of biomaterial which inhibited biofilm formation without affecting normal microbial flora.
