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 ...

Effect of Occlusal Adjustment and Subsequent Repolishing on the Translucency Parameter, Contact Angle, and Flexural Strength of Different Types of Glazed Monolithic Zirconia

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objectives This study evaluated the effects of material and surface condition (glazed vs. polished after simulated occlusal adjustment) on translucency parameter, contact angle, and flexural strength of four monolithic zirconia. Materials and Methods Disk‐shaped specimens (n = 80, Ø12 × 1 mm) were fabricated from four monolithic zirconia ...

Effects of gastric acid on surface roughness, microhardness, fracture strength, and color change of dental ceramics: A systematic review of in vitro studies

Journal of Prosthodontics, EarlyView.
Abstract Purpose This systematic review evaluated the effects of simulated gastric acid (SGA) on surface and mechanical properties of dental ceramics to answer the research question: Does immersion in SGA alter the surface roughness, microhardness, fracture strength, and color of dental ceramics?
