Adaptation, Marginal, and Occlusal Quality of Monolithic Zirconia Crowns: Effect of the CAD/CAM Milling Protocol

open access: yesJournal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objectives Variables related to CAD/CAM processing can affect the final quality of all‐ceramic crowns. This study aims to evaluate the effect of the milling protocol on the adaptation, marginal and occlusal quality of monolithic zirconia crowns.

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

open access: yesJournal 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,

Ultra‐High‐Speed Sintering of 3.5Y‐TZP Zirconia: Time Reduction Without Compromising Translucency

open access: yesJournal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objectives To assess, firstly, the impact of three sintering speeds on translucency and grain size of 3.5Y‐TZP zirconia (Katana HT) across clinically relevant thicknesses, and secondly, the effect of thermocycling on translucency. Materials and Methods Disc specimens were fabricated at six thicknesses (0.7–2.0 mm) and sintered using SLOW (7 h),

Effect of Glazing Dwell Time and Cooling Duration on Flexural Strength and Surface Microhardness of 3 mol% Yttria‐Stabilized Tetragonal Zirconia: An In Vitro Study

open access: yesJournal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective To evaluate the effect of glazing dwell time and cooling duration on the flexural strength and surface microhardness of high‐translucency 3 mol% yttria‐stabilized tetragonal zirconia polycrystal (3Y‐TZP). Materials and Methods Total of 108 rectangular zirconia specimens (20 × 4 × 2 mm) were fabricated from preshaded monolithic blocks

Processing and characterization of additively manufactured 2 mol% yttria-stabilized zirconia

open access: yesOpen Ceramics
2 mol% yttria-stabilized zirconia (2YSZ) has attracted increasing attention in recent years. Its key characteristic is the lower degree of stabilization compared to 3 mol% yttria-stabilized zirconia (3YSZ), which results in higher fracture toughness.

Long‐Term Clinical and Radiographic Outcomes of Ceramic Dental Implants: An 11‐Year Retrospective Cohort Study

open access: yesJournal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective Evidence on zirconia dental implants remains limited. This retrospective study evaluated clinical and radiographic outcomes of contemporary ceramic implant systems placed in private practice with variable follow‐up of up to 11 years.

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

open access: yesJournal 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.

Assessment of fit accuracy and retentive strength of additively manufactured zirconia crowns luted to Ti‐base abutments with different resin cements: An in vitro study

open access: yesJournal of Prosthodontics, EarlyView.
Abstract Purpose This study investigated the influence of cement gap size on the marginal and internal fit, and cement gap size and type on retention of additively manufactured zirconia (AM‐Z) crowns on titanium bases (Ti‐base). Materials and Methods A total of 135 zirconia crowns were designed with three different cement gap sizes: 20 µm, 30 µm, and ...
