Fracture of porcelain-veneered gold-alloy and zirconia molar crowns using a modified test set-up

Acta Biomaterialia Odontologica Scandinavica, 2015
Objective: The main aim of this study was to compare fracture load and fracture mode of yttria-stabilized tetragonal zirconia polycrystal (Y-TZP) and metal-ceramic (MC) molar crowns using a modified test set-up to produce fractures similar to those seen ...

Internal fit of two all-ceramic systems and metal-ceramic crowns

Journal of Applied Oral Science, 2012
OBJECTIVES: The aim of this study was to investigate the internal fit (IF) of glass-infiltrated alumina (ICA - In-Ceram Alumina), yttria-stabilized tetragonal zirconia polycrystals (Y-TZP - IPS e.max ZirCAD), and metal-ceramic (MC - Ni-Cr alloy) crowns ...

CBCT artefact-burden of zirconia-based as compared to titanium implants for different beam energies: an analytical approach

Scientific Reports, 2022
Beam hardening artefacts induced by highly-dense material (e.g. metal) is a common quality issue in maxillofacial Cone Beam Computed Tomography (CBCT-) images. This experimental and analytical study investigated attenuation patterns of two typical dental

Structure–Activity Relationships in Methyl‐Driven Overhauser Effect DNP

Chemistry – A European Journal, EarlyView.
Dynamic nuclear polarization (DNP) was investigated in a wide array of methyl‐containing Blatter radicals to identify design principles for the synthesis of an Overhauser DNP polarizing agent. Fourteen different radicals were synthesized, which revealed that only radicals possessing sterically unhindered methyl groups in sites of high spin density were

Evolutionary and Epidemiological Characterization of Multidrug‐Resistant Escherichia coli Isolated From Pangolins in China

Integrative Zoology, EarlyView.
ABSTRACT Malayan pangolin populations have fallen to a critically endangered level, and illegal trafficking of wild pangolins is a global problem. Little is known about antimicrobial‐resistant bacteria (MDRB) harbored by pangolins, although pangolins are frequently consumed as food or used in traditional medicine. In this study, we report for the first

The dual incretin agonist tirzepatide blunts nicotine‐induced behaviours and neurochemistry in male mice

British Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Nicotine dependence remains one of the leading causes of morbidity and mortality worldwide, with high relapse rates and post‐cessation weight gain representing persistent barriers to sustained abstinence. The incretin hormones glucose‐dependent insulinotropic polypeptide (GIP) and glucagon‐like peptide‐1 (GLP‐1) have ...

Effect of Cigarette Smoking on the Surface Roughness, Color, and Translucency of Zirconia Produced by Additive and Subtractive Manufacturing

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective To compare the surface roughness, color stability, and translucency of zirconia produced by additive manufacturing (AM) and subtractive manufacturing (SM) after exposure to cigarette smoking. Materials and Methods A total of 60 disc‐shaped specimens were fabricated from 2 methods: AM (INNI Cera BCM W500/1000) and SM (VITA YZ T).

Long‐Term Esthetic‐Functional Rehabilitation of Unilateral Cleft Lip and Palate With a Cross‐Arch Monolithic Zirconia Fixed Dental Prosthesis Following Multidisciplinary Treatment: 5‐Year Post‐Prosthetic Follow‐Up

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective This case report describes the esthetic‐functional rehabilitation of a patient with unilateral complete cleft lip and palate who was managed multidisciplinarily from 10 to 18 years of age, and reports the clinical outcome 5 years after definitive prosthetic rehabilitation, which was undertaken after late secondary alveolar bone ...
