Comparison of the mechanical properties of translucent zirconia and lithium disilicate
The Journal of Prosthetic Dentistry, 2018Three mol% yttria-stabilized tetragonal zirconia polycrystal (3Y-TZP) possesses excellent mechanical properties but is relatively opaque. Five mol% yttria-stabilized zirconia polycrystal (5Y-ZP) offers improved translucency, but many of its clinical properties have not been compared with those of 3Y-TZP and lithium disilicate.The purpose of this in ...

This in vitro study aimed to evaluate and compare the fracture resistance of lithium disilicate crowns fabricated from two CAD/CAM ceramic materials—IPS e.max CAD (Ivoclar Vivadent) and CEREC Tessera™ (Dentsply Sirona)—cemented using two different luting agents: glass ionomer cement and dual-cure self-adhesive resin cement.

Er:YAG laser debonding of zirconia and lithium disilicate restorations
The Journal of Prosthetic DentistryYttria-stabilized tetragonal zirconia polycrystal (Y-TZP) restorations of different formulations are being used increasingly in monolithic form for a range of clinical applications. Using rotary instruments to remove such restorations for any purpose is challenging, but they can be removed conservatively with erbium lasers.

Objective: CAD/CAM technology allows fabrication of thin lithium disilicate (LD) veneers to a LD crown substructure in place of using traditional feldspathic porcelain (FP) which has inferior mechanical properties. This project investigated the effect of different LD veneer applications to LD substructure on the biaxial flexural fatigue of LD veneer ...
