GC everX Posterior is a fiber-reinforced composite designed to be used as a replacement for dentin in conjunction with a conventional composite such as G-aenial Posterior for enamel replacement. The short fibers in GC everX Posterior form a perfect substructure to reinforce any composite restoration in large cavities. Indications: reinforced material for direct composite restorations, especially in large posterior cavities including: cavities with 3 or more surfaces, cavities with missing cusps, deep cavities (including Class I, II, and endodontically treated teeth), cavities after amalgam replacement (especially since the placement of amalgam often leads to the initiation of cracks and fractures of the cusps), and cavities where inlays and onlays are also indicated.
