Is Additive Manufacturing of Dental Zirconia Comparable to Subtractive Methods When Considering Printing Orientation and Layer Thickness? A Systematic Review and Meta‐Analysis

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective The aim of this systematic review and meta‐analysis was to determine whether the production of monolithic dental zirconia using additive manufacturing (AM), with consideration of different printing directions and layer thicknesses, enhances its mechanical and physical properties relative to subtractive manufacturing (SM ...

Electrical and Hydrogen Reduction Enhances Kinetics in Doped Zirconia and Ceria: II. Mapping Electrode Polarization and Vacancy Condensation in YSZ

, 2017
Knowing the correlation between grain boundary mobility and oxygen potential in yttria stabilized zirconia (YSZ), we have utilized the grain size as a microstructural marker to map local oxygen potential. Abrupt oxygen potential transition is established

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).

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 (
