Objective: This study was aimed to compare the wear of four types of the ceramic dental materials with different surface treatments.
Material and Methods: Porcelain (low-fusing feldspathic, monolithic zirconia, lithium disilicate glass, and leucite glass-ceramic) samples (9 x 3 mm) were prepared with different surface treatments (glazed and mechanical polished). Samples were mechanically loaded in a chewing simulator (600.000 cyles of 50N) and 64 teeth were used to simulate as the antagonist. To evaluate the wear of the samples before and after the test, samples were scanned by 3D scanner, Dental Wings 7 Series. Then they were transformed into the digital platform. Surface analysis was performed by using an optical profilometer and scanning electron microscope. A sensitive digital scale was used for weight measurements of antagonist's teeth.
Results: It was a significant difference between the volume values of the groups with mechanical polish and the groups with glaze, except for zirconia samples (p 0.05). In terms of the weight measurement results of the antagonist teeth, while leucite reinforced overglazed group (PRG) has the highest weight loss as a result of wear, ZP group has the least weight loss.
Conclusion: It was concluded that glazed groups of ceramics lose more substances than polished groups, and that causes more wear on antagonist teeth. Zirconia ceramics showed less substance loss, and that causes less wear on antagonist teeth.
