Abstract

Abstract

The abrasion responses were tested on four acrylic veneer materials, K+B Plus®, K+B 75®, Isosit®, and Ivocron®. The studies were performed in two independent research laboratories. Two different brushing machines were used with an abrasive slurry. The results were used for comparing the degree of abrasion for the resin materials. Three analytical methods of measuring the degree of abrasive wear were used: surface profile measurement, microscopic evaluation, and measurement of loss of volume. Isosit showed the best abrasion resistance of the four materials tested.
