Fracture Load of Zirconia Crowns Based on Preparation and Cement Type
Abstract
Limited research has been published evaluating the failure of cubic zirconia crowns with non-retentive preparations. Objective: The purpose of this study was to evaluate the effect of axial wall height (AWH) and cement type on the fracture load of cubic zirconia crowns. Methods: Ninety extracted maxillary human third molar teeth were prepared with standardized crown preparations with AWHs of zero, two, or four millimeters (n=10).The preparations were scanned and crown restorations were designed (Omnicam, Dentsply/Sirona).
