Comparative studies on the adhesion of a silicone elastomer to a chromium-cobalt dental alloy.
Rocatec, Kevloc and Siloc bonding systems were used to bond Molloplast-B silicone elastomer to a metal alloy denture base material. The mechanical strength of the bonds was examined using tensile tests. Two groups of tests were performed, 30 samples after one day storage in water and 30 samples after 6 months in water at 37 degrees C. At both testing times, the Rocatec system exhibited high reproducibility and the highest mean results. For the Kevloc system the values were lower while the Siloc system yielded the lowest values. The strength of samples, bonded with the Rocatec system, was improved by storage in distilled water at 37 degrees C.
