Effect of Deep Margin Elevation on the Fracture Resistance of Maxillary Molar Zirconia Crowns
Background: The purpose of this in vitro study was to evaluate the fracture resistance of maxillary molar zirconia crowns cemented with deep margins relocated with resin composite. Methods: A maxillary right first-molar typodont tooth was prepared for a complete-coverage zirconia crown and modified to have: (1-DME) a 3...
