[Chemical bond of adhesive and palladium alloys].
Bond strength after SiOx-C-coating of palladium-alloys by heat treatment (Silicoater MD) and by sandblasting (Rocatec) to Bis-GMA-adhesives was evaluated. Up to 150 d storage in water we observed a mean bond strength of at least 25 N/mm2 for a palladium-tin-alloy using the Silicoater MD system and for a palladium-silver-alloy using the Rocatec-device/modified Bis-GMA-adhesive. There were only small differences between selfcuring and lightcuring preservation at the one hand and unpreserved samples at the other hand. Since the selfcuring preservation is easier to handle we favour this one. The bond strength of 25 N/mm2 is to be compared with the cohesive strength of human enamel which is known to be about 10 N/mm2. Bond strength after SiOx-C-coating (Silicoater MD) of a palladium-silver-alloy was about 10 N/mm2 only.
