Wear of composite resin veneering materials in a dual-axis chewing simulator

The attritional wear of human enamel and four different composite resins for the veneering of crowns was evaluated in a dual‐axis chewing simulator over up to 1 200 000 loading cycles. Enamel showed less wear than the composite resins. However, an ultrafine compact‐filled composite resin (Targis®) showed a wear not statistically significantly different from that of enamel. The other composite resins showed a statistically significantly higher wear than enamel regardless whether microfine, ultrafine midway‐filled or ultrafine compact‐filled.
