Abstract

The Tribological evaluation of commercial dental composite resins containing prepolymerized particle fillers was investigated. Composite resins such as Metafil, Silux Plus, Heliomolar, and Palfique Estelite were selected as specimens. In the wear tests, a ball-on-flat wear test method was used. The friction coefficient of Metafil was quite high. The wear resistance of Silux Plus and Palfique Estelite was better than that of Metafil and Heliomolar under the same experimental conditions. The main wear mechanism of the composite resins containing prepolymerized particle fillers was abrasive wear caused by the brittle fracture of the prepolymerized particles and the debonding of the filler and the matrix.
