Time-dependent fracture probability of bilayer, lithium-disilicate-based, glass–ceramic, molar crowns as a function of core/veneer thickness ratio and load orientation

Nov 25, 2017 by in Dental Materials Comments Off on Time-dependent fracture probability of bilayer, lithium-disilicate-based, glass–ceramic, molar crowns as a function of core/veneer thickness ratio and load orientation

Abstract Recent reports on bilayer ceramic crown prostheses suggest that fractures of the veneering ceramic represent the most common reason for prosthesis failure. Objective The aims of this study were…
