Tribocorrosion in dental implants: an in-vitro study

26/11/2015

The relative motion between the zirconia abutment and the titanium implant in the presence of saliva might lead to tribocorrosion and consequently metal ion release and ion contamination of peri -implant tissues. In order to study this issue tribocorrosion, tests were performed in open circuit potential (OCP) and during anodic polarization in two different configurations: titanium ball pin on zirconia plate and zirconia ball pin on titanium plate. For both configurations, the OCP decreases and the anodic current increases during the wear testing. The results showed different tribocorrosion response between configurations. The higher OCP drop and anodic current was obtained for the configuration titanium ball pin on zirconia plate.
