Surface roughness and bond strength between Y-TZP and self-adhesive resin cement after air particle abrasion protocols
(2016-09-01)
The aim of this study was to evaluate the influence of different air particle abrasion (APA) protocols - with variations in particle types, duration of application, and the distance between the device tip and the ceramic ...
Aging effect of atmospheric air on zirconia surfaces treated by nonthermal plasma
(2015-01-01)
Purpose: The purpose of this study was twofold: 1) to characterize the zirconia (Y-TZP) surfaces through scanning electronic microscopy associated with energy-dispersive spectroscopy and atomic force microscopy after the ...
Microestrutura e resistência da zircônia parcialmente estabilizada
(Universidade Estadual Paulista (Unesp), 2022-06-29)
O objetivo deste estudo foi desenvolver um vidro termicamente compatível
ao ser infiltrado em uma zircônia parcialmente estabilizada por óxido de ítrio (5YPSZ), caracteriza-la, avaliar sua confiabilidade estrutural e ...
Low-fusing porcelain glaze application on 3Y-TZP surfaces can enhance zirconia-porcelain adhesion
(2016-09-01)
The aim of this study was to assess whether surface treatment improves zirconia-porcelain adhesion. The 3Y-TZP blocks were cut into squares, then polished and sintered. The zirconia surface treatments were performed as ...
Adesão à cerâmica Y-TZP: estudo da deposição de nanofilmes à base de sílica na superfície da Y-TZP
(Universidade Federal de Santa MariaBROdontologiaUFSMPrograma de Pós-Graduação em Ciências Odontológicas, 2013-08-15)
This study in vitro proposed to evaluate the influence of silica-based film coated on the Y-TZP surface on the durability bond strength (BS) between ceramic and resin cement. Eighty Y-TZP blocks (5x5x4 mm) were obtained, ...
Bonding of Y-TZP to Dentin: Effects of Y-TZP Surface Conditioning, Resin Cement Type, and Aging
(Operative Dentistry Inc, 2014-05-01)
Purpose: To evaluate the effects of two surface treatments, aging, and two resin cements on shear bond strength between dentin and yttrium-stabilized tetragonal zirconia polycrystal ceramic (Y-TZP).Materials and Methods: ...
Effects of surface treatments on Y-TZP phase stability, microstructure and osteoblast cell response
(Elsevier, 2015-12)
The effects of hydrothermal and phosphoric acid treatments on the tetragonal ZrO2 stability and surface microstructure were determined for 3mol% yttria- partially stabilized zirconia (Y-TZP) and Al2O3 doped Y-TZP (Y-TZPA). ...
Failure modes of Y-TZP abutments with external hex implant-abutment connection determined by fractographic analysis
(2016-07-01)
Yttria-stabilized tetragonal zirconia (Y-TZP) was introduced as ceramic implant abutments due to its excellent mechanical properties. However, the damage patterns for Y-TZP abutments are limited in the literature. Fractographic ...
Sintering, microstructure and hardness of Y-TZP- 64S bioglass ceramics
(Elsevier, 2018-04)
3 mol% yttria-partially stabilized zirconia (Y-TZP) powder and a sol-gel derived CaO- P2O5- SiO2 (64S) bioglass, were used to produce Y-TZP- 64S slip cast compacts. The compacts with 10.5 and 19.9 vol% 64S were sintered ...
Bond strength of zirconia to different core materials
(2016-10-01)
Background: Since bonding to zirconia is still questionable,the aim of this study was to evaluate the bond strength of yttrium-stabilized tetragonal zirconia polycrystal (Y-TZP) to different materials used to manufacture ...
