The aim of this study was to evaluate the sliding-induced wear of five commercial resin materials for reconstructing occlusion opposing an Au-Ag-Pd alloy. A polymethylmetacrylate (PMMA) resin and enamel were used as the control. The evaluation of the wear was to measure the volume and depth of wear of resin materials and the volume of wear of Au-Ag-Pd alloy.
There was a great variation in the wear of tested resin materials. A light curing composite resin for inlay (ES) and a light curing veneering hard resin (CE) had a wear near that of the PMMA resin (UN). Wear of a heat curing composite resin for inlay and a light curing composite resin for filling were less than that of UN, ES and CE, and were greater than that of a hard resin denture tooth and enamel. The smallest wear was shown by the hard resin denture tooth. The difference of wear between the hard resin denture tooth and enamel was not statistically significant.
