TLDR
It is found that strong scientific and collaborative foundations exist for the continued understanding and improvement of dental ceramic systems.Abstract:
This article presents a brief history of dental ceramics and offers perspectives on recent research aimed at the further development of ceramics for clinical use, at their evaluation and selection, and very importantly, their clinical performance. Innovative ceramic materials and ceramics processing strategies that were introduced to restorative dentistry since the early 1980s are discussed. Notable research is highlighted regarding (1) wear of ceramics and opposing enamel, (2) polishability of porcelains, (3) influence of firing history on the thermal expansion of porcelains for metal ceramics, (4) machining and CAD/CAM as fabrication methods for clinical restorations, (5) fit of ceramic restorations, (6) clinical failure mechanisms of all-ceramic prostheses, (7) chemical and thermal strengthening of dental ceramics, (8) intraoral porcelain repair, and (9) criteria for selection of the various ceramics available. It is found that strong scientific and collaborative foundations exist for the continued understanding and improvement of dental ceramic systems.read more

Relative translucency of six all-ceramic systems. Part I: Core materials
Michael Heffernan,Steven A. Aquilino,Ana M. Diaz-Arnold,Debra R. Haselton,Clark M. Stanford,Marcos A. Vargas +5 more
TL;DR: There was a range of ceramic core translucency at clinically relevant core thicknesses and one-way analysis of variance and Tukey's multiple-comparison test were used to analyze the data.

Structural reliability of alumina-, feldspar-, leucite-, mica- and zirconia-based ceramics
TL;DR: It is concluded that industrially prepared ceramics are more structurally reliable materials for dental applications although CAD-CAM procedures may induce surface and subsurface flaws that may adversely affect this property.

Relative translucency of six all-ceramic systems. Part II: Core and veneer materials
Michael Heffernan,Steven A. Aquilino,Ana M. Diaz-Arnold,Debra R. Haselton,Clark M. Stanford,Marcos A. Vargas +5 more
TL;DR: A range of translucency was identified in the veneered all-ceramic systems tested and may affect their ability to match natural teeth.

Antibacterial activity of dental composites containing zinc oxide nanoparticles.
Berdan Aydin Sevinç,Luke Hanley +1 more
TL;DR: It is demonstrated here that zinc oxide nanoparticles (ZnO-NPs) blended at 10% (w/w) fraction into dental composites display antimicrobial activity and reduce growth of bacterial biofilms by roughly 80% for a single-species model dental biofilm.
Journal ArticleDOI
Ceramics in restorative and prosthetic dentistry 1
TL;DR: Significant improvements seem possible in the clinical use of ceramics based on engineering solutions derived from the study of clinically failed restorations, on the incorporation of higher levels of “biomimicry” in new systems, and on the synergistic developments in dental cements and adhesive dentin bonding.

Assessment of Appearance Match by Visual Observation and Clinical Colorimetry
William M. Johnston,E.C. Kao +1 more
TL;DR: The overlap in ranges of the color differences for those comparisons rated matches and mismatches indicates the importance of other factors in appearance matching, such as translucency and the effects of other surrounding visual stimuli.

Hydrolytic Degradation of Dental Composites
TL;DR: The leakage of filler elements from four composites after storage in water was investigated by use of atomic absorption spectrophotometry and confirmed previous findings that leaching of silicon from different composites is strongly dependent on filler composition.

Visual and Instrumental Colorimetric Assessments of Small Color Differences on Translucent Dental Porcelain
TL;DR: The results support the use of the CIELAB colorimetric system in dentistry as a means of evaluating color by differences and could serve as a valuable tool for material selection and restoration design, particularly in the area of aesthetic restorative dentistry.
