In Vitro Bioactivity of Hydrogen Peroxide Modified Titanium: Effects of Surface Morphology and Film Thickness

Abstract:

Anatase films with various morphologies were formed on Ti surface through different approaches using hydrogen peroxide solutions. A porous anatase surface was found to favor apatite deposition in SBF, or in vitro bioactivity. Thicker films with wider crack gaps also showed enhanced in vitro bioactivity. However, the most predominant effect was the abundance of Ti-OH functional groups incorporated in the anatase films.
