Resin bonding to various alloys by means of the Silicoater MD System.
The aim of this research was to evaluate the effectiveness of the Silicoater MD System for bonding resin to four different Brazilian alloys. The alloys included the following proprietary materials: Duracast, Durabond II, Palad and Premium. Biobond II, a popular nickel-chromium alloy has been used as control. Dentacolor served as the veneering agent. All specimens were thermo-cycled for 24 hours between 41 degrees and 131 degrees C at a dwell time of one minute per temperature. Shear-bond strengths ranged from 1667 to 2842 psi. Scanning electron microscopic evaluation demonstrated no gap formations at the resin/metal interface for all of the aforementioned systems, the Silicoater MD System demonstrated acceptable retention efficiency in five types of metallic alloys.
