New multi-layered zirconias: Composition, microstructure and translucency [PDF]

open access: yesDental Materials, 2019
To fully realize the range of indication and clinical advantages of the new multi-layered zirconias, a comprehensive understanding of their chemical composition, microstructure, low temperature degradation (LTD) resistance, and translucency properties is paramount.A zirconia system (Katana, Kuraray Noritake), including 3 distinct grades of multi ...

Fracture load of colored and non-colored high translucent zirconia three-unit fixed dental prosthesis frameworks

open access: yesActa Biomaterialia Odontologica Scandinavica, 2018
Aim: The use of colored translucent zirconia may enable restorations of a more natural tooth-like appearance than previous opaque white zirconia. The shift from non-colored to colored zirconia may however entail a risk of reduced strength. The aim of the

Comparison of cytomorphometry and early cell response of human gingival fibroblast (HGFs) between zirconium and new zirconia-reinforced lithium silicate ceramics [PDF]

open access: yes, 2018
New zirconia-reinforced lithium silicate ceramics (ZLS) could be a viable alternative to zirconium (Y-TZP) in the manufacture of implantological abutments—especially in aesthetic cases—due to its good mechanical, optical, and biocompatibility properties.

Evaluation of translucency of monolithic zirconia and framework zirconia materials

open access: yesThe Journal of Advanced Prosthodontics, 2016
The opacity of zirconia is an esthetic disadvantage that hinders achieving natural and shade-matched restorations. The aim of this study was to evaluate the translucency of non-colored and colored framework zirconia and monolithic zirconia.The three groups tested were: non-colored framework zirconia, colored framework zirconia with the A3 shade ...

Comparative Evaluation of the Translucency of Monolithic Zirconia

open access: yesThe Journal of Contemporary Dental Practice, 2020
New techniques are being developed to invent zirconia with high translucency and better esthetics leading to the development of several brands of monolithic zirconia. The aim of this study is to compare the translucency of three brands of zirconia available for the fabrication of monolithic restorations.An in vitro study was designed to compare the ...

Damage tolerance of six dental zirconias with different translucencies [PDF]

open access: yesBiomaterial Investigations in Dentistry, 2020
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. Little is known regarding how these alterations affect other properties than translucency and flexural strength.
