eFiber by Preat is a BisGMA and PMMA impregnated E-glass fibers. All the advantages of the first generation Preat Perma Fiber, but without the need to “wet” the material!
Use fiber to prevent Stress Cracks from starting before they begin. Increase fatigue resistance. Increase flexural strength.
The BIS-GMA allows eFiber to bond with light cure composites and well as acrylic (PMMA).
eFiber provides 28 MPa of adhesive strength to etched enamel/dentin and 27 MPa to composite.
