Abstract

The objective of the present investigation was to evaluate the resistance of metal-resin bonding using the Silicoater® MD system (Kulzer), five types of retention in the metal structure, and three commercial Ni-Cr alloys: Duceranium U, Wiron 99 and Wirocer. A total of 90 samples were submitted to the shearing test. Statistical analysis of the results permitted us to conclude that retention versus alloy interaction was statistically significant at a 1% level of probability, the highest mean value being obtained with the Wirocer alloy with mechanical retention with 0.6 mm spheres. The lowest mean values were observed with the Wiron 99 alloy with chemical retention. (AU)
