Interactions Between the Physiological Environment and Titanium-Based Implant Materials: From UndersTitanium and its alloying elements, such as aluminum and vanadium, can then be released as ions, which might trigger an immune system response and reduce biocompatibility. Several surface modifications have been proposed in order to improve the bone-bonding ability of titanium and its alloys, facili
