Abstract The aim of this study was to evaluate the effect of convergence angle( 12° – 20° ) of tooth preparation on the internal fit and marginal accuracy of monolithic zirconia crowns. Marginal and internal gap distances measurements were done by internal replica technique. Digital microscope connected to computer software , at 60 magnification was used to measure marginal and internal gap. |
