With the limitations of this study, the veneered crowns were inferior to the non-veneered ones in terms of fracture load. Moreover, it can be deduced by numerical simulation that, interface between veneer layer and core material might be one of the stress concentration areas initiating crack development and growth, resulting in fracture. As the results of in vitro and numerical studies are coincident with each other, selection of stronger veneer ceramics which have less possibility to perform flaws in fabrication can reduce the chances of chipping and delamination under function.
