The effect of repetitive firing cycles on physical and optical properties of zirconia reinforced lithium silicate ceramics
… showed that repetitive firing cycles reduced e.max® and Vita Suprinity’s® translucency, but not that of Celtra® Duo, which showed no significant difference. All materials of greater thickness exhibited less translucency, and e.max® CAD had the highest mean light transmission; however, it was not …

Comparative study of physical properties of zirconia based dental ceramics
… specimens (Kavo Everest ZS-blanks with IPS e.max® Ceram and IPS e.max® Zirpress) were submitted to the fatigue followed by biaxial flexural strength test. The microstructure was analysed using AFM, and elemental analysis and fracture pattern were analysed via SEM. Additionally, stress induced …
