TCP Doped with Metal Ions Reinforced with Tetragonal and Cubic Zirconia [PDF]

open access: goldBiomimetics, 2023
Ceramic biocomposites based on bioactive tricalcium phosphate doped with metal ions are a strategy for obtaining good biomimetics for human bone composition. Manufacturing with PMMA porogen also induces bone-like porosity morphology. The poor strength of

A 3‐year controlled clinical trial comparing high‐translucency zirconia (cubic zirconia) with lithium disilicate glass ceramic (e.max) [PDF]

open access: goldClinical and Experimental Dental Research, 2023
Introduction The rate of clinical success in veneers, under esthetics, has achieved a range of 18 months to 20 years. In a plethora of studies, it registers a success rate reaching 75% and even 100%.

X-ray photoemission spectroscopy determination of the InN/yttria stabilized cubic-zirconia valence band offset [PDF]

open access: bronze, 2007
The valence band offset of wurtzite InN(0001)/yttria stabilized cubic-zirconia (YSZ)(111) heterojunctions is determined by x-ray photoemission spectroscopy to be 1.19±0.17 eV giving a conduction band offset of 3.06±0.20 eV.

Optical, Structural, and Biological Characteristics of Rapid-Sintered Multichromatic Zirconia [PDF]

open access: yesBiomedicines
Background: To overcome the esthetic limitations of dental monolithic zirconia restorations, multichromatic systems were developed to combine improved structural integrity with a natural shade gradient that mimics the optical properties of natural teeth.

Transition to Electronic Conduction at the Onset of Flash in Cubic Zirconia

open access: greenSSRN Electronic Journal, 2019
We report in-situ measurements of impedance spectroscopy during flash experiments with single crystals of cubic-yttria stabilized zirconia, conducted in ambient air at 300 °C to 700 °C under a direct current electric field. Platinum electrodes transition from blocking to non-blocking behavior just before the onset of flash, indicating a transition to ...

Grain growth in ultrafine-grained Y-TZP ceramics [PDF]

open access: yes, 1997
Grain growth in dense ultrafine-grained (120–600 nm) tetragonal ZrO2-Y2O3 ceramics is studied as a function of temperature. At all temperatures investigated both segregation and phase partitioning occur.

Factors Affecting the Color Change of Monolithic Zirconia Ceramics: A Narrative Review [PDF]

open access: yesJournal of Functional Biomaterials
Zirconia restorations are widely used in dentistry due to their high esthetic expectations and physical durability. However, zirconia’s opaque white color can compromise esthetics.
