Evaluation of UDMA's potential as a substitute for Bis-GMA in orthodontic adhesives
Dental Materials, 2013To investigate the effect of UDMA %, of a range of filled UDMA:TEGDMA resins, on viscosity, degree of conversion and shear bond strength. Furthermore, to compare between model filled and unfilled UDMA adhesives, and clinically used orthodontic adhesives on these properties.Four filled and four unfilled resins with a UDMA to TEGDMA weight ratio 50:50 ...

Water sorption of polymethacrylate networks: Bis‐GMA/TEGDM copolymers
Journal of Biomedical Materials Research, 1987AbstractPolymethacrylate networks were made by copolymerization of a range of compositions of bis‐GMA and triethylene glycoldimethacrylate (TEGDM). Polymerization was initiated both by heating with benzoyl peroxide or by photopolymerization (λ > 400 nm) using camphoroquinone as sensitizer. The uptake of water increased from 3 to 6% as the proportion

Network structure of Bis-GMA- and UDMA-based resin systems
Dental Materials, 2006The commonly used dental base monomers 2,2-bis[p-(2'-hydroxy-3'-methacryloxypropoxy)phenylene]propane (Bis-GMA) and 1,6-bis(methacryloxy-2-ethoxycarbonylamino)-2,4,4-trimethylhexane (UDMA) require the use of a diluent monomer, such as triethylene glycol dimethacrylate (TEGDMA).

The effects of BIS-GMA and TEG-DMA on female mouse fertility
Dental Materials, 2006The current study evaluated the effect of bisphenol A glycerolate dimethacrylate (BIS-GMA) and triethyleneglycol dimethacrylate (TEG-DMA) on female mouse fertility.Adult female mice were exposed to BIS-GMA or TEG-DMA (0, 25 and 100 microg/kg) intragastrically daily for 28 d and then mated with sexually mature untreated male mice and after mating their ...

Multifractality in the copolymerization of Bis‐GMA/TEGDMA by pulsed photoacoustics
Journal of Applied Polymer Science, 2008AbstractFractal development during polymerization of a dimethacrylate system (Bis‐GMA/TEGDMA) has been studied through the analysis of time series obtained sequentially by pulsed photoacoustics. The photoacoustic signals as obtained in situ during photopolymerization of Bis‐GMA/TEDGMA were analyzed by rescaled range analysis, dispersion analysis, and ...

Marginal Adaptation of BIS-GMA-based Composites Containing Various Diluents
Journal of Dental Research, 1981Marginal leakage is a result of inadequate marginal seal. Curing shrinkage of the resin is a major contributor to breaking the margin seal. The chemical structure and concentration of the diluent in the resin formulation affects curing shrinkage and marginal adaptation of composite restorations.

Mechanical properties of BIS‐GMA resin short glass fiber composites
Journal of Biomedical Materials Research, 1989AbstractThe use of short glass fibers as a filler for dental restorations or cement resins have not been examined extensively. The mechanical properties and untreated glass fibers (5 μm dia × 25 μm) in Bis‐phenol A glycidyl methacrylate (BIS‐GMA) diluted with triethylene‐glycol dimethacrylate (TEGDMA) resin were investigated for possible use as a ...

Evaluation of a phosphonate BIS-GMA resin as a bracket adhesive.
Quintessence international (Berlin, Germany : 1985), 1992Panavia is a modified phosphate ester of dimethacrylate that purportedly forms a strong bond to tooth structure and to metals. The ability of this adhesive to bond orthodontic brackets to enamel was compared to the bond strengths of a no-mix bracket adhesive and a paste/paste autopolymerizing composite resin.
