Novel translucent monolithic zirconia fixed restorations in the esthetic zone

Clinical Case Reports, 2022
Novel translucent monolithic zirconia has improved optical properties, and it may fulfill patient's esthetic demands and overcome the chipping risk of bilayer metal‐ceramic restorations. New zirconia's microstructures allow us to mimic natural teeth.

Effect of Successive Bleaching Treatments Followed by Staining on Color, Whiteness, and Translucency of Polymer‐Based CAD‐CAM Materials

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective To evaluate differences in color, whiteness, and translucency of CAD‐CAM materials after successive bleaching treatments and coffee immersion. Materials and Methods Lava Ultimate (LU) and VITA Enamic (VE) were divided into four groups (n = 12): untreated (control), 35% hydrogen peroxide (WH), 10% carbamide peroxide (OP), or WH ...

Effect of sintering cycle on the strength and translucency of multilayered zirconia

Journal of Prosthodontics, EarlyView.
Abstract Purpose A newly introduced sintering protocol promises to offer higher translucency while not significantly compromising the flexural strength of the material. However, the effect of the novel sintering protocol has not been thoroughly validated.
