What is Bis-GMA used for?

What is Bis-GMA used for?

Bis-GMA is the product of bisphenol A and glycidyl methacrylate that undergoes polymerization. It is used as a bond implant material, as well as the resin component of dental sealants and composite restorative materials. Bis-GMA has been used for most dental fillers for more than a decade now.

What is GMA material?

Bis-GMA (bisphenol A-glycidyl methacrylate) is a resin commonly used in dental composite, dental sealants. and dental cement. It is the diester derived from methacrylic acid and the bisphenol A diglycidyl ether.

Is Bis-GMA toxic?

The results from the current study suggest that BisGMA has an alternative mechanism of toxicity compared to other methacrylate monomers.

Is Bis-GMA the same as BPA?

BPA is a precursor to the resin monomer Bis-GMA. During the manufacturing process of Bis-GMA dental sealants, Bisphenol A (BPA) might be present as an impurity or as a degradation product of Bis-DMA through esterases present in saliva.

Is Bis-GMA hydrophilic?

Although Bis-GMA forms a polymeric backbone is relatively more hydrophobic, less prone to absorb water than do the highly hydrophilic monomers such as HEMA, PENTA, BPDM, Phenyl-P and others16; neither Bis-GMA nor its derivatives co-momonors (i.e. Bis-GMA-E) and other more hydrophobic monomers (i.e.UDMA) used in …

Is Bis-GMA a monomer?

Introduction. Bisphenol A-glycidyl methacrylate (bisGMA) is the most widely used monomer to prepare dental restorative composite resins [1], [2]. It is a high molecular weight monomer with two methacrylate moieties.

Is there Bis-GMA in your filling material?

White fillings, commonly called resin composites, are not made from pure BPA, but a BPA derivative. Further, the white fillings used in our office contain a compound called bis-GMA, which does NOT convert to BPA.

What is Tegdma?

Introduction. Triethylene glycol dimethacrylate (TEGDMA) is a resin monomer widely used in the composition of dentin bonding agents and composite resins to restore teeth structures impaired by caries and/or fractures.

Is there Bis GMA in your filling material?

Is BIS GMA a monomer or polymer?

The organic matrix of dental resin composites combines multi-methacrylate monomers to optimize the handling properties, polymerization rate, final degree of conversion, and mechanical properties. The most traditional organic system is composed of the highly viscous BisGMA as base monomer and TEGDMA as co-monomer [1].

What is UDMA dental?

In recent years, the elution of monomers from dental materials has been a cause for public concern. Urethane dimethacrylate, commonly abbreviated to UDMA, is one of the monomers that are most often tested with regard to elution from and cytotoxicity of resin-based materials.
