Abstract:

Marginal fit is one of the most important criteria for the long-term clinical success of crowns. Insufficient marginal adaptation may result in increased plaque accumulation, periodontal disease, secondary caries, and restoration failure. Preparation finish line configuration has a direct effect on the marginal fit of restorations. Objective: This study examined marginal fit (marginal discrepancy) of full coverage ceramic restorations milled to different finish line margins.
