A new approach for Y-TZP surface treatment: evaluations of roughness and bond strength to resin cemen

J. appl. oral sci; 27 (), 2019
Abstract Objective This study aims to evaluate the effect of sonochemical treatment on the surface of yttria-stabilized tetragonal zirconia (Y-TZP) before and after the final sintering. Material and Methods Twenty-eight Y-TZP discs were divided into four groups (n=7), according to surface treatment: ...

Polishing of ground y-tzp ceramic is mandatory for improving the mechanical behavior

Braz. dent. j; 29 (5), 2018
Abstract It evaluated the effect of aging by Low Temperature Degradation (LTD), executed after post- processing surface treatments (polishing, heat treatment and glazing), on the surface characteristics (micromorphology and roughness) and on the structural stability (phase transformation and mechanical b...

A study of the modification of Y-TZP and resin cement with titanium dioxide nanotubes

Titanium dioxide nanotubes (TiO2) have been applied to enhance the mechanical properties of dental materials. Yttria-stabilized tetragonal zirconia polycrystals (Y-TZP) has been increasingly used in dentistry. Aside from its optimal clinical results, Y-TZP is prone to failures related to insufficient thi...

Effect of ceramic thickness, grinding, and aging on the mechanical behavior of a polycrystalline zirconia

Abstract Monolithic restorations of Y-TZP have been recommended as a restorative alternative on prosthetic dentistry as it allows a substantial reduction of ceramic thickness, which means a greater preservation of tooth structure. However, the influence of grinding and aging when using a thinner layer of...
