Abstract:ObjectivesTo compare volumetric wear of lithium disilicate against different ceramic (3 mol% yttria‐stabilized (3Y) zirconia, 5 mol% yttria‐stabilized (5Y) zirconia, lithium disilicate, porcelain and enamel antagonists).Materials and MethodsForty lithium disilicate (e.max CAD) specimens (n = 8/antagonist) were wet sanded to 1200grit SiC and mounted into a UAB wear device. Antagonist spheres (diameter = 4.75 mm) were made from polished 3Y zirconia, 5Y zirconia, lithium disilicate, porcelain and human enamel. A … Show more
