Optimizing Hard and Soft‐Tissue Esthetics With Anterior Cantilever Zirconia Ceramic Resin‐Bonded Fixed Dental Prostheses

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective The replacement of missing maxillary lateral incisors poses both functional and esthetic challenges, not only from a restorative but also from a periodontal aspect. This case report presents a step‐by‐step protocol for ideal hard and soft‐tissue esthetics with cantilever zirconia ceramic resin‐bonded fixed dental prostheses (RBFDPs).

Damage tolerance of six dental zirconias with different translucencies

Biomaterial Investigations in Dentistry, 2020
Purpose High-translucent dental zirconia has been introduced as a suitable material for anterior monolithic restorations. The material composition differs from traditional 3Y-TZP both with regard to yttria content and grain size.

Managing Fractured Ceramic Restorations: Current Evidence and Best Practices—A Scoping Review

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective This scoping review aims to assess the effect of different protocols on the outcome of ceramic restoration repairs. Materials and Methods An electronic search was conducted in three databases (PubMed, Cochrane Library, and Embase), up to July 31st 2025, with previously identified MeSH terms. Results Out of the 2423 records, title and

Fatigue Performance and Failure Loads of Composition‐Gradient Multilayer Zirconia: Partial‐Coverage Restorations Versus Single Crowns at Different Thicknesses

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective This study investigated the influence of restoration type (partial‐coverage versus crown) and ceramic‐layer thickness on the fatigue behavior and failure load of monolithic composition‐gradient multilayer zirconia (4Y‐PSZ/5Y‐PSZ) molar restorations. Material and Methods Seventy‐two CAD/CAM‐fabricated monolithic zirconia restorations (

The Effect of Glazing and Repeated Firing on Color, Translucency, and Flexural Strength of Different Types of Zirconia: An In Vitro Study

Ceramics
This study evaluated the impact of glazing and multiple firing on the flexural strength, translucency, and color stability of three types of zirconia: 3 mol% yttria-stabilized tetragonal zirconia polycrystals (3Y-TZP), 4 mol% yttria partially stabilized ...

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.

Contact damage in an yttria stabilized zirconia: Implications

Journal of Materials Science: Materials in Medicine, 2007
This paper presents the results of a combined experimental and computational study of contact damage in a 3 mole% yttria partially stabilized zirconia (3-YSZ) that is relevant to hip implants and dental restorations. Contact-induced loading in real applications is idealized using Hertzian contact model to explain plasticity phenomena and failure ...

A Hybrid Approach Using AI‐Assisted Chairside Staining for an Anterior Metal‐Ceramic Crown

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective To describe a hybrid approach for a metal‐ceramic anterior crown, combining traditional ceramic layering with a chairside staining technique guided by recipes generated using an artificial intelligence‐based software. Clinical Considerations The clinical case presented a step‐by‐step protocol from both laboratory and clinical ...

Atomically ordered solute segregation behaviour in an oxide grain boundary

Nature Communications, 2016
Solute segregation is challenging to experimentally identify at the atomic scale. Here, the authors report the direct observation of atomic site-dependent solute segregation behaviour in an yttria-stabilized zirconia grain boundary by atomic-resolution ...
