Effect of substructure fabrication method and design on the fracture resistance properties of metal–ceramic restorations

open access: yesJournal of Prosthodontics, EarlyView.
Abstract Purpose In metal–ceramic restorations, the substructure fabrication method and design may affect the prognosis of the prosthesis. This study evaluated and compared the fracture resistance of metal–ceramic restorations fabricated with different substructure fabrication methods using two different alloy powders and designs.

Effects of gastric acid on surface roughness, microhardness, fracture strength, and color change of dental ceramics: A systematic review of in vitro studies

open access: yesJournal of Prosthodontics, EarlyView.
Abstract Purpose This systematic review evaluated the effects of simulated gastric acid (SGA) on surface and mechanical properties of dental ceramics to answer the research question: Does immersion in SGA alter the surface roughness, microhardness, fracture strength, and color of dental ceramics?

Pressed lithium disilicate glass ceramics: Microstructural characterization, in vitro and in silico nonlinear dynamic analysis for biaxial flexural strength

open access: yesJournal of Prosthodontics, EarlyView.
Abstract Purpose To evaluate the mechanical properties of lithium disilicates, and to assess the predictive capability of in silico models for biaxial flexural strength (BFS). Materials and Methods Specimens of four heat‐pressed lithium disilicates (IPS e.max Press, Rosetta SP, LiSi Press, Vintage Prime Press) were obtained.

The effect of toothpaste and thermal aging on extrinsically stained additively manufactured zirconia: A comparative study on surface roughness and stain durability

open access: yesJournal of Prosthodontics, EarlyView.
Abstract Purpose The purpose of this in vitro study was to compare the average surface roughness (Ra) and stain durability of extrinsically stained additively manufactured zirconia, after brushing with different toothpastes and thermal cycling, with those of subtractively manufactured zirconia and lithium disilicate.

Peri‐implantitis—Is it mainly a clinician‐initiated complication of implant therapy?

open access: yesPeriodontology 2000, EarlyView.
Abstract Aim The high prevalence of peri‐implantitis is concerning, with a growing consensus that the majority of cases are complications initiated by clinician‐related errors rather than classic pathology. A primary predisposing factor for peri‐implantitis is exposure of the micro‐rough implant surfaces to the peri‐implant sulcus after treatment ...

Examination of industrial practice of ceramic glaze making with emphasis on particle size distribution

open access: yes, 2007
This article examines the existing industrial practice of glaze making with emphasis on particle size and particle size distribution of glazes. The importance of fine grinding affecting reduction in particle size on lowering the maturing temperature has ...

A Journey Between Science and the Arts: Templates for the Depiction of the Pineapple (Sixteenth to Eighteenth Centuries)

open access: yesRenaissance Studies, EarlyView.
ABSTRACT Native to America, the pineapple—Ananas comosus (L.) Merr.—delighted the Europeans who came across it. The fruit was mentioned by the voyagers and missionaries who observed and tasted it in the Americas and, from the 1500s onwards, infused reports, chronicles and natural history treatises with colour and flavour.

Small ceramic pot showing centimetre scale crystals within the glaze

open access: yes, 2010
Careful heat treatment of the glaze produces a very small number of willemite (zinc orthosilicate, Zn2SiO4) nuclei which can grow to centimetre dimensions over the course of a few hours at a suitably high temperature.
