Solid-solubilities of grain-growth inhibitors in WC-Ni-based cemented carbides: experimental investigations and thermodynamic calculations

open access: yesJournal of Materials Research and Technology, 2020
Cr3C2, TaC and VC are the most widely used grain growth inhibitors (GGIs) in cemented carbides. The inhibition effectiveness and the formation of brittle carbides by over-doping these GGIs are closely associated with their solubilities in the binder ...

Effect of Silane Incorporation on the Bonding Performance of Universal Adhesives to Dentin

open access: yesJournal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Purpose The effect of silane in universal adhesives (UAs) on dentin adhesion remains unclear. Therefore, this study evaluated the dentin bonding of UAs with and without silane immediately and after thermocycling. Materials and Methods Sixty‐four sound human molars were randomly assigned to eight groups according to silane incorporation (UAs ...

Effect of margin thickness and cement gap on the fabrication and fit accuracy of additively manufactured crowns in definitive resins with different filler content

open access: yesJournal of Prosthodontics, EarlyView.
Abstract Purpose To evaluate how commercially available composite resins in varying filler content affect the fabrication and fit accuracy (trueness and precision) of additively manufactured (AM) definitive crowns with different margin thickness and cement gaps by comparing them to subtractively manufactured (SM) polymer‐infiltrated ceramic crowns ...
