Abstract The aim of the present study was to evaluate the fracture resistance of zirconia reinforced lithium silicate (vita suprinity) single crowns with two margin geometries (feather edge and chamfer edge). Evaluation of the fracture resistance of restorations was carried out under cyclic loading and thermal cycling. SEM (scanning electron microscope) and srereomicroscope testing was also performed to evaluate the mode of failure. |
