Osteoconductivity of Superhydrophilic Anodized TiO₂ Films Using Hydrothermal Treatment

Abstract:

In this study, we conferred superhydrophilic properties on anodized TiO₂ coatings using a hydrothermal treatment, and developed a method to maintain this surface until implantation. The osteoconductivity of these coatings was evaluated with in vivo tests. A hydrothermal treatment made the surface of as-anodized samples more hydrophilic, up to a water contact angle of 13 deg. Storage in PBS(-) led to a reduction in the water contact angle, because of the adsorption of the inorganic ions in the solution, and the sample retained its high hydrophilicity for a long time. As the water contact angle decreased, the hard tissue formation ratio increased continuously up to 58 %, which was about four times higher than the hard tissue formation ratio on as-polished Ti.
