The adhesion mechanism of dental adhesive resin to the alloy. Adhesive ability of dental adhesive resin to the cleaned metal surface obtained by hydrogen gas reduction method.

Abstract

With the cleaned metal surface without passive film or an oxide layer, chromium, cobalt, and iron show excellent bonding strength, indicating values similar to 18-8 stainless steel. Therefore the existence of a passive film and oxide layer at the interface metal/resin is not essential for metal-resin bonding. The adhesive ability decreases in the order: Cr congruent to Co congruent to Fe greater than Cu greater than Ag greater than Au congruent to Ni greater than Pt greater than Pd.
