The impact of corrosion on titanium implants and on patient health is not well determined or elucidated based on current knowledge. Although titanium has the ability to passivate through the formation of a protective titanium oxide film and has excellent biocompatibility, it is susceptible to alteration under certain conditions. The objective of our study is to specify the factors inducing corrosion and their influences on titanium implants, namely fluorinated media, pH and temperature in comparison with cobalt-chromium. Electrochemical measurements and surface observation were carried out in these implants and compared with cobalt-chromium. In our study, inside an acidic environment and high temperature solution that a resistance to corrosion was objectified. Basic pH values, low temperatures and very high fluoride concentrations are the main factors that increase the risk of corrosion of titanium. The conditions in the oral cavity are likely to trigger corrosion phenomena on a titanium implant. [ABSTRACT FROM AUTHOR] |
