Abstract

PURPOSE Intraoral adjustments of monolithic zirconia (MZ) necessitate intraoral grinding and polishing procedures, causing surface topography changes. The effect of various polishing and glazing procedures on surface roughness, topographical and phase changes of CoCr compared to zirconia, and assessment of the wear of the opposing dentition has been evaluated in this study. MATERIALS AND METHODS One group of square Cobaltchromium (CoCr) and four groups of sintered and polished zirconia specimens (12 × 12 × 1mm) were fabricated (N = 5,
