Effect of substructure fabrication method and design on the fracture resistance properties of metal–ceramic restorations

Journal of Prosthodontics, EarlyView.
Abstract Purpose In metal–ceramic restorations, the substructure fabrication method and design may affect the prognosis of the prosthesis. This study evaluated and compared the fracture resistance of metal–ceramic restorations fabricated with different substructure fabrication methods using two different alloy powders and designs.

Pressed lithium disilicate glass ceramics: Microstructural characterization, in vitro and in silico nonlinear dynamic analysis for biaxial flexural strength

Journal of Prosthodontics, EarlyView.
Abstract Purpose To evaluate the mechanical properties of lithium disilicates, and to assess the predictive capability of in silico models for biaxial flexural strength (BFS). Materials and Methods Specimens of four heat‐pressed lithium disilicates (IPS e.max Press, Rosetta SP, LiSi Press, Vintage Prime Press) were obtained.
