Effect of adhesive metal primers on bonding a prosthetic composite resin to metals.
The effect of three adhesive metal primers on the shear bond strength of a light-cured prosthetic composite resin bonded to cobalt-chromium or silver-palladium-copper-gold casting alloy was evaluated. The adhesive metal primers used were New Metacolor opaque bonding liner, Cesead opaque primer, and 0.5% VBATDT in acetone. A newly prepared light-cured opaque resin was used to bond a light-cured veneering resin to dental alloys. The specimens were thermocycled in water for up to 20,000 cycles between 4 degrees C and 60 degrees C, and shear bond strengths were recorded. The light-cured composite resin bonded most strongly to Co-Cr alloy primed with Cesead primer and to Ag-Pd-Cu-Au alloy with the VBATDT primer. These adhesive metal primers may be clinically acceptable for bonding a light-cured prosthetic composite resin to base or precious metal.
