A total of 10 groups were prepared from feldspar ceramic (18), 3Y-TZP (36), and 5Y-TZP (36). Feldspar ceramics were glazed; half of the zirconia groups of each material were polished, and the other half were polished-then-glazed. Feldspar ceramic, 3Y-TZP, and 5Y-TZP materials were divided into two groups due to the enamel and dentin antagonists. Ninety extracted third molars (45 enamel and 45 dentin) were used as antagonists. Tooth surfaces were scanned with a 3D laser scanner before and after testing. Samples were subjected to 2,40,000 cycles with a dual-axis chewing simulator (50 N, 5\u00b0C\u201355\u00b0C).
