Improvement of Osteoconductivity of Titanium using Surface Modification

Abstract

Synopsis Many techniques for the surface modifi cation of titanium and its alloy have been proposed from the viewpoint of the improvement of the bioactivity. This review contains an overview of the methods of surface treatments such as coatings with osteoconductive compounds, e.g., hydroxyapatite (HAp) and titania. Coating methods are classifi ed into following two groups; pyro-processing and hydro-processing. In this review, we mainly outlined the hydro-processing for the coating of the HAp and titania on the titanium substrate. And also, mentioned the processing to create the metallic surface with fi ne and coarse roughness. Moreover, the evaluation by the implantation of the surface-modifi ed samples in the rats' tibia was explained.
