Determinants of marginal gap of single crowns before cementation: An umbrella review
Crown type, crown fabrication material, and crown fabrication method demonstrated no significant effect on marginal gaps. The impression replica instrument overvalued marginal gaps in comparison with microscopy. Based on the results of this study, the contemporary acceptable limit for in vitro crown marginal gap is 120 µm.
