Abstract

Micro- and nano-porous TiO 2 films were created on the surface of Ti implants using micro-arc oxidation and anodic titanium oxide treatments, respectively, to load a sol-gel derived silica xerogel for the controlled release of the antibiotic drug, tetracycline-hydrochloride (TCH). When the silica xerogel containing TCH was loaded into porous TiO 2 films, a very high drug loading efficiency was observed compared to when it was loaded in Ti implants without a TiO 2 film. Moreover, TCH was released in a controlled manner for up to 7 days.
