Abstract
Introduction: Zirconia restorations present long-term clinical survival. It’s low translucency makes them esthetically less than lithium disilicate. The newly introduced ultra translucent (UT) zirconia blocks might help to overcome the aesthetic drawbacks for fabrication of laminate veneers.
Aim of this study: To evaluate the translucency of UT zirconia laminates and to assess the effect of tribochemical silica coating on its bond strength to the resin cement, using lithium disilicate as control.
Materials and Methods: Forty four disc-shaped specimens were fabricated and divided into two main groups; Group (I): Translucency test: the specimens (10×0.5mm (n=20)) were divided into 2 subgroups: Subgroup (IA) UT Zirconia, subgroup (IB) e.max CAD. Group (II): Shear bond strength (SBS) test, specimens (5mm x 4mm (n=24)) were divided into 3 subgroups. Subgroup (IIA): UT zirconia specimens treated only with airborne-abrasion, subgroup (IIB): UT zirconia specimens coated with tribochemical silica after the airborne-abrasion, subgroup (IIC): e.max CAD etched with hydrofluoric acid and silanated. For translucency measurements spectrophotometer was used.
Results: Translucency results showed p value
