Improving fatigue resistance of translucent 4Y‐PSZ zirconia through glass gradation

European Journal of Oral Sciences, EarlyView.
Abstract To evaluate the effect of graded glass infiltration on the fatigue behavior and mechanical reliability of translucent 4Y‐PSZ zirconia before and after hydrothermal aging, disc‐shaped specimens were fabricated by uniaxial pressing and divided into control and glass‐graded groups (n = 36/group).

Translucency of 3D‐Printed 3Y‐ and 5Y‐Doped Zirconia

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objectives To evaluate and compare the translucency of 3D‐printed zirconia materials: 3Y tetragonal zirconia polycrystal (3Y‐TZP) and 5Y partially stabilized zirconia (5Y‐PSZ). Material and Methods 3D‐printed 5Y‐PSZ and 3Y‐TZP materials fabricated using digital light processing (DLP) were investigated.

Effects of Substructure Color and Restoration Thickness on the Final Color of Ultra‐Translucent Zirconia Ceramics

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective This in vitro study aimed to evaluate the effects of substructure color and restoration thickness on the final color of shade‐gradient ultra‐translucent zirconia ceramics. Material and Methods A total of 180 flat‐shaped ultra‐translucent zirconia specimens (5Y‐PSZ) with thicknesses of 0.4, 0.6, and 0.8 mm (n = 60) were fabricated and

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 ...

Systematic Review Evaluating the Influence of Veneering Design on the Clinical Outcome of All‐Ceramic Implant‐Supported 3–4 Units and Full Arch Fixed Dental Prostheses

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective To systematically assess survival, failure, and complication rates of all‐ceramic implant‐supported monolithic and micro‐veneered FDPs (i‐FDPs) in partially/completely edentulous patients compared to veneered restorations. Materials and Methods An electronic search identified prospective clinical studies on all‐ceramic i‐FDPs with at

Influence of Different Multilayer Zirconia Materials on the In Vitro Load‐Bearing Capacity of Resin‐Bonded Fixed Partial Dentures in the Posterior Region

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective Comparison of the load‐bearing capacity and failure pattern of posterior resin‐bonded fixed partial dentures (RBFPDs) differing in retainer design, zirconia material, and vertical nesting position. Materials and Methods RBFPDs replacing a maxillary first molar were fabricated with 2 retainer designs (inlay‐retained, IR; wing‐retained,
