Abstract

Background: Marginal accuracy is animportant factor influencing the clinicalsuccess and longevity of fixed dental restorations. Excessive marginal gaps mayincrease cement dissolution, microleakage,secondary caries, and periodontalcomplications. Computer-aided design andcomputer-aided manufacturing (CAD/CAM)
