Degradation of titanium-based implants

Abstract During mastication, cyclic micromovements can be generated at dental implant connections leading to complex wear in the presence of the corrosive biological environment, such as acidic substances, bacteria metabolites, fluorides, and hydrogen peroxide. That can result in simultaneous degradation of dental implant materials by wear and corrosion processes, known as tribocorrosion. This chapter gathers knowledge from diverse fields contributing to a better understanding of the degradation mechanisms of titanium-based implants by wear-corrosion interactions in the oral environment.
