The comparison of wear characteristics of prosthodontic restorative materials.
OBJECTIVE
To assess the mutual wear characteristics of various prosthodontic restorative materials.


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.


CONCLUSIONS
Various prosthodontic restorative materials had wear characteristics affecting each other.
