ABSTRACT
We have previously reported that insertion of coarse particles of beta-Quartz Glass Ceramic Insert (Megafiller) into a composite resin markedly reduced the polymerization shrinkage of resin restorative materials. In this study, we examined the effects of Megafiller insertion on wear resistance evaluated by the glass beads abrasion test, and the conventional toothbrushing abrasion test. The depth of wear was determined by measuring the thickness of the specimen before and after the wear tests using a profile projector accurate to 1 micron. In general, the depth of wear of the composites was reduced by Megafiller insertion, but the differences in the depth of wear between composites with and without the Megafiller were not significant except for a few materials. There were slight differences in the wetness of Megafiller in some composite resins.
