TL;DR: Altered environments induced by bacterial biofilms and/or inflammatory processes may trigger oxidation of the surface of titanium dental implants, which can lead to permanent breakdown of the oxide film and hinder re-integration of the implant surface with surrounding bone.

TL;DR: Implant surface oxidation occurred in bacteria-containing medium even at early stages of immersion (2 days), and incremental corrosion resulted in dissolution of metal ions and debris into the testing solution.

TL;DR: The goal is to simulate the oral environment where an implant will be exposed to a combination of acidic electrochemical environment and mechanical forces, and to understand the synergistic effects of mechanical forces and bacterial biofilm on the surface of dental implants.

TL;DR: TiZr and ZrO2 dental implant surfaces were not more susceptible to colonization and surface degradation by oral Streptococcus species than commercially pure Ti implants.

TL;DR: The ability of bacteria in the oral environment to solely induce changes in the oxidation states of titanium and subsequent corrosion of the implant surface, even in the absence of mechanical loads is demonstrated.
