Influence of Heliobond on Microtensile Bond Strength of a New BIS-GMA Free Versus BIS-GMA Containing Composite Resin Restoration

open access: yesOpen Access Macedonian Journal of Medical Sciences, 2023
AIM: The main objective of this study was to assess the micro-tensile bond strength (µTBS) of a free bisphenol-a-diglycidyl-ether-dimethacrylate (Bis-GMA) resin composite restorative material compared to a Bis-GMA-containing resin composite following the application of a hydrophobic coating (heliobond).

Properties of acrylic bone cements formulated with Bis‐GMA

open access: yesJournal of Biomedical Materials Research Part B: Applied Biomaterials, 2005
AbstractExperimental cement formulations were prepared by replacing part of the methylmethacrylate (MMA) liquid phase of a conventional surgical cement with an equivalent weight of 2,2‐bis [4(2‐hydroxy‐3‐methacryloxypropoxy) phenyl] propane (Bis‐GMA), which is the reaction product of diglycidyl ether of bisphenol A and methacrylic acid.

The effect of UDMA and Bis-GMA irradiation period on residual monomers in resin packable composite

open access: yesDental Journal, 2019
Background: Residual monomers are non-polymerized monomers which can cause clinical harm, for example inflammation, to oral cavity tissue while the remaining monomers can potentially be carcinogenic.

Development of new diacrylate monomers as substitutes for Bis-GMA and UDMA

open access: yesDental Materials, 2021
Bisphenol A-glycidyl methacrylate (Bis-GMA) and urethane dimethacrylate (UDMA) are widely used as the primary components of (meth)acrylic monomers. However, the use of Bis-GMA, which is a bisphenol A derivative, in dentistry is being questioned after bisphenol A was found to exhibit estrogenic activity. Although UDMA is being considered as a substitute

Analysis of Major Components Contained in Bis-GMA Monomer.

open access: yesDental Materials Journal, 1999
The major components contained in commercial Bis-GMA monomer were isolated by thin layer chromatography (TLC) and identified by NMR and high resolution mass spectroscopy. In addition to the two major components already known (Bis-GMA and Iso-bis-GMA), an unknown hydrophilic third major component was isolated and identified as 2,2-[4-(2-hydroxy-3 ...

Influence of hydrogen bonding on properties of BIS-GMA analogues

open access: yesJournal of Materials Science: Materials in Medicine, 1997
The influence of chemical structure on the important properties of composite matrix resins is being systematically investigated. This study addresses the relationships between pendent side chain structures, viscosity and curing shrinkage. In particular, viscosity is known to be greatly influenced by intermolecular interactions, such as hydrogen bonding,
