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

open access: yesJournal 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 ...

Does treatment‐induced surface roughness of 3 mol% yttria‐stabilized tetragonal zirconia polycrystals influence the wear of opposing restorative materials? An in vitro study

open access: yesJournal of Prosthodontics, EarlyView.
Abstract Purpose This study aimed to investigate whether different surface treatments applied to 3 mol% yttria‐stabilized tetragonal zirconia polycrystals (3Y‐TZP), with comparable mean roughness (Ra) values, result in comparable values of additional surface roughness parameters, and to evaluate the influence of zirconia surface topography on vertical ...

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.

Kinetics of Hydrothermally Induced Transformation of Yttria Partially Stabilized Zirconia

open access: yes, 2007
Yttria-stabilized zirconia undergoes tetragonal to monoclinic phase transformation under hydrothermal conditions in the temperature range of 150–350 °C. Phase transformation accompanied by volume change in bulk yttria partially stabilized zirconia (YPSZ)

Effects of low‐pressure plasma and ytterbium fiber laser on zirconia surface properties and bond strength to gingiva‐colored composite

open access: yesJournal of Prosthodontics, EarlyView.
Abstract Purpose To evaluate and compare the effects of surface activation by low‐pressure plasma (LPP) and surface texturing by ytterbium fiber laser (YFL) treatments on zirconia surface properties and shear bond strength (SBS) to a gingiva‐colored indirect composite under aged and non‐aged conditions.

Pyramidal Structures on Yttria‐Stabilized Zirconia after High Temperature Exposure at 1500°C: New Features on an Old Material

open access: yesAdvanced Engineering Materials, Volume 28, Issue 17, 9 September 2026.
New features on yttria‐stabilized zirconia after exposure at 1500°C: Newly discovered pyramidal structures on an old material. After exposure at 1550°C on the cross section of YSZ new features, namely pyramidal structures are discovered. These structures grow with time, increase in numbers, appear as singularities, are often arranged in strings, and ...

High Power Density, Low Temperature, Solid Oxide Fuel Cells at Elevated Oxygen Partial Pressure

open access: yesAdvanced Energy Materials, Volume 16, Issue 33, 2 September 2026.
Elevated pO2${{p}_{{{{\mathrm{O}}}_2}}}$ improves oxygen reduction reaction (ORR) kinetics, thus reducing electrode area specific resistance (ASR). The effect of pO2${{p}_{{{{\mathrm{O}}}_2}}}$ in open circuit potential (OCP) and ASR is demonstrated on both Sr0.5Sm0.5CoO3‐δ‐Gd0.1Ce0.9O2‐δ (SSC‐GDC) composite cathodes and our recently developed nano‐PSC
