Novel glass-ceramics for dental restorations.
BACKGROUND There are many different ceramic systems available on the market for dental restorations. Glass-ceramics are a popular choice due to their excellent esthetics and ability to bond to tooth structure allowing a more conservative approach. However, at present, these materials have insufficient strength to be used reliably in posterior regions of the mouth. PURPOSE The aim of this revi...
متن کاملDental Ceramics/Bioactive Glass Composites: Characterization and Mechanical Properties Investigation
Apart from a good bioactive behavior, composite materials for dental applications should attain high mechanical properties. Thus, the aim of this work was the fabrication and characterization of novel sol-gel derived dental ceramics/bioactive glass composites and the investigation of their mechanical properties such as flexural strength and Weibull modulus. Fourier Transform Infrared Spectrosco...
متن کاملDegradability of fluorapatite-leucite ceramics in naturally acidic agents.
This study was conducted to evaluate the titratable acidity and effect of naturally acidic agents on the surface microhardness, elemental composition, and surface morphology of fluorapatite-leucite ceramics. One hundred and ten ceramic disks (IPS d.SIGN), 12.0 mm in diameter and 2.0 mm in thickness, were fabricated. Before immersion, the baseline data of Vickers microhardness and elemental comp...
متن کاملLeucite content of selected dental porcelains.
Leucite is a major crystalline component of dental porcelains. The presence of tetragonal leucite in dental porcelains increases their coefficients of thermal expansion due to its high coefficient of thermal expansion (20-25 x 10(-6)/degrees C). This is particularly useful for those porcelains designed for bonding to precious metals and nickel alloys. The purpose of this study was to determine ...
متن کاملBiocompatibility study of lithium disilicate and zirconium oxide ceramics for esthetic dental abutments
PURPOSE The increasing demand for esthetically pleasing results has contributed to the use of ceramics for dental implant abutments. The aim of this study was to compare the biological response of epithelial tissue cultivated on lithium disilicate (LS2) and zirconium oxide (ZrO2) ceramics. Understanding the relevant physicochemical and mechanical properties of these ceramics will help identify ...
