Abstract

The properties of implant materials used in humans may have important influences on the outcomes of clinical treatments. Recently, titanium and titanium alloys have been extensively employed as in-vivo implant materials, due to their generally favorable biocompatibility, high resistance to corrosion, and relatively low cost. On the other hand, even when using chemically identical materials, the biocompatibility of an implant or its stability depends heavily on its surface structure, as well as the thickness and properties of the surface oxide film. As the characteristics of the implant surface have been reported to play an important role in the in-vivo reactions of implants, a great deal of interest has recently been focused on different surface treatment methods. Currently, there are a variety of methods with which titanium implant surfaces are treated. The anodizing method is an electrochemical technique, which forms a rough, thick oxidized capsule with nanotubular structures on the implant surface. To increase the biocompatibility and bone regeneration and to improve the current shortcomings of Ti and Ti alloy (Ti6Al4V)implants, we applied a uniquely fabricated nanotubular coating over the surface of such implants.
