Galvanic Corrosion Behaviour of Ti and Ti6Al4V Coupled to Noble Dental Alloys

Cerapall ® 2 → Pontor ® 2 → V-Gnathos ® Plus → Pagalin ® 2. Values of the icouple, varying between 0.2 and 0.7 μA cm -2 , were obtained for the four noble alloys when coupled to pure titanium or to the titanium alloy, respectively. Among the couples studied the Pontor® 2 | Ti was found to be the more resistant galvanic couple, while the Cerapall® 2 | Ti6Al4V presents the lowest corrosion resistance.
