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 30mm, height 4mm, and a spherical shape with a diameter of 5mm and length of 6mm. 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.
