Effect of sliding wear mechanism condition on the wear behavior of dental biocomposite materials

Background: The purpose was to study the effect of sliding condition on the wear behavior of nanofilled composite material under two-body wear test mechanism. Materials and Methods: In this study, a supreme composite material with nanofiller was subjected to abrasion test procedures' in vitro conditions. In this study, the test samples were divided into two groups and subjected 50 N wear force, 1.6 Hz wear frequency, 240,000 wear cycles, constantly 37°C temperature, and 0.3 mm and 0.6 mm sliding conditions through wear test procedures, respectively. The volume loss in the wear area of the test samples after the wear test procedures was analyzed using a noncontact three-dimensional profilometer. In addition, microstructure analysis was performed by selecting random test samples from each group using scanning electron microscopy. Results: As per the data obtained during this study, with an increase in the amount of lateral movement, the volume loss in the composite material had also increased after wear test procedures. Conclusion: However, the increase in volume loss in the wear area of the composite material did not show a linear relationship with the amount of lateral movement.
