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?

The effects of material thicknesses and substrates on the translucency and color masking ability of additively manufactured definitive crown materials

Journal of Prosthodontics, EarlyView.
Abstract Purpose To investigate the translucency of the new 3D‐printable materials concerning thickness and the color masking ability of each material against different substrate colors. Materials and Methods Ninety square‐shaped specimens (12.0 mm × 12.0 mm) of two new 3D‐printable materials: ceramic‐infiltrated hybrid resin composite (VS) and light ...

Marginal Misfit Assessment in Common Restorative Materials for Cement‐Retained Fixed Implant Prostheses: An In Vitro Comparative Study

Clinical and Experimental Dental Research, Volume 12, Issue 2, April 2026.
ABSTRACT Objectives To assess the vertical discrepancy at the abutment–crown interface (ACI) for cement‐retained crowns fabricated from three commonly used restorative materials across implants featuring external and internal connections. Materials and Methods A total of 30 implants with external (EC) and internal (IC) connections were included in this

Impact Resistance of Yttria- and Ceria-Doped Zirconia Ceramics in Relation to Their Tetragonal-to-Monoclinic Transformation Ability

Ceramics
In this work, the impact resistance of three zirconia ceramics was investigated: two yttria-stabilized zirconia (3Y-TZP and 1.5Y-TZP) and a ceria-stabilized-zirconia (Ce-TZP) composite.

Exploring Cation Selection and Disorder Within Entropy‐Driven A6B2O17 (A = Zr/Hf, B = Nb/Ta) Oxides

Journal of the American Ceramic Society, Volume 109, Issue 4, April 2026.
ABSTRACT We investigate the local atomic and electronic structure, thermodynamic stability, and defect chemistry of A6B2O17 (A = Zr/Hf, B = Nb/Ta) oxides using first‐principles density functional theory (DFT) calculations. We examine both ordered unit cells as well as fully disordered special quasirandom structures to clearly discern the effects of ...
