The titanium implants have been widely accepted as an ideal material for orthopaedic and dental surgery, due to good biocompatibility, strength and osseointegration. However, the commercially used titanium implants are not without complications; corrosion has been a big concern. As described, corrosion of titanium implants is rare. Still, it can result in the release of titanium ions and particles that activate inflammatory pathways related to the development of peri-implant diseases (e.g., peri-implantitis). These factors may cause tissue necrosis, bone resorption, and ultimately, implant failure. Recent works have increasingly reported corrosion as one of the major factors in the progression of peri-implantitis connected with bacterial infection and lack of oral cleanliness, which lead to implant failure. Corrosion product may trigger the activation of the immune system, like macrophage activation and production of pro-inflammatory cytokines. In this review article, the literature regarding corrosion of titanium implants and their relationship with peri-implant diseases in the light of changing approaches to avoid such hazards is evaluated. Surface treatments, the use of modern titanium alloys, bioactive coatings and customised implant solutions are considered, in order to improve the corrosion resistance and prolong the lifetime of titanium implants. The most important research will be to combine these advances, eventually leading to enhanced patient success and less implant failure from problems related to corrosion.
