Effect of glazed and polished 3Y-TZP and 5 mol% yttria-stabilized partially stabilized zirconia on fibroblast behavior: In vitro study

The Journal of Indian Prosthodontic Society
Aim: To evaluate and compare the viability, proliferation, and adhesion of HGFs on glazed and polished surfaces of 3 mol% yttria-stabilized tetragonal zirconia (3Y-TZP) and 5 mol% yttria-stabilized partially stabilized zirconia (5Y-PSZ).

High temperature deformability of ductile flash-sintered ceramics via in-situ compression

Nature Communications, 2018
Flash sintering allows for rapid ceramic processing, but the mechanical behavior of such ceramics remains poorly understood. Here, the authors compress micropillars of yttria stabilized zirconia to show flash sintering promotes outstanding plasticity.

A Comprehensive Multimodal Study of La0.45Sr0.45TiO3 Structure as Matrix for the Exsolution Process: From the Average to the Local Scale

Small, EarlyView.
We present a multimodal, multiscale study of La0.45Sr0.45TiO3 combining experimental and computational approaches to probe its local structure. The results reveal A‐site ordering along [001] and loss of centrosymmetry driven by electrostatic effects.

Ultra‐High‐Speed Sintering of 3.5Y‐TZP Zirconia: Time Reduction Without Compromising Translucency

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objectives To assess, firstly, the impact of three sintering speeds on translucency and grain size of 3.5Y‐TZP zirconia (Katana HT) across clinically relevant thicknesses, and secondly, the effect of thermocycling on translucency. Materials and Methods Disc specimens were fabricated at six thicknesses (0.7–2.0 mm) and sintered using SLOW (7 h),

Effect of Glazing Dwell Time and Cooling Duration on Flexural Strength and Surface Microhardness of 3 mol% Yttria‐Stabilized Tetragonal Zirconia: An In Vitro Study

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective To evaluate the effect of glazing dwell time and cooling duration on the flexural strength and surface microhardness of high‐translucency 3 mol% yttria‐stabilized tetragonal zirconia polycrystal (3Y‐TZP). Materials and Methods Total of 108 rectangular zirconia specimens (20 × 4 × 2 mm) were fabricated from preshaded monolithic blocks

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.

Influence of Simulated Clinical Finishing/Polishing Protocols and Thermocycling on the Surface Integrity and Mechanical Performance of 3Y‐TZP

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Purpose This in vitro study evaluated the influence of different finishing and polishing protocols associated with thermocycling aging on surface roughness, flexural strength, and topography of 3Y‐TZP. Methods and Materials Two hundred and eighty‐six specimens (16 × 3 × 1 mm) were distributed into 22 groups (n = 13) according to the finishing ...
