Abstract
AIM: To assess the mutual wear characteristics of various prosthodontic restorative materials. MATERIALS AND METHODS: Samples were prepared using base metal alloy, ceramics and aesthetic methyl metacrylate resin materials in cylinders with a diameter of 30 mm, height 4 mm, and a spherical shape with a diameter of 5 mm and length of 6 mm. The mutual wearing process of samples on each other in groups was tested using a pin-on disc wear tester machine. RESULTS: The data obtained were evaluated by means of variance analysis and T-test. It was determined that the percentages of the mutual wearing of the restorative materials were statistically significant (p<0.001), but whether the samples were in the upper or lower position had no statistical significance. CONCLUSION: Various prosthodontic restorative materials had wear characteristics affecting each other.
