AbouteverX Posterior is a fibre-reinforced composite designed to be used as dentin replacement, in conjunction with a conventional composite such as Essentia Universal shade used as enamel replacement. The short fibres make it a sub-structure intended to reinforce composite restorations in large cavities.Indications Cavities with 3 surfaces or more to be restored Cavities with missing cusps Deep cavities, including class I, class II, and endodontically treated teeth Cavities after amalgam replacement, especially where amalgam placement may have initiated cracks and cusp fracture Cavities where onlays and inlays would also be indicated Note: GC everX Posterior should always be covered with a layer of light-cured composite.Advantages Short fibres help prevent and stop the progression of fractures in the restoration Fracture toughness equivalent to dentin and almost double to any composite Minimal horizontal shrinkage as fibres contribute to shrinkage reduction in the direction of their orientation 4 to 5 mm increments can be cured simultaneously Reliable bond to the overlaying composite as well as to the tooth structure Product typeFibre-reinforced composite for dentin replacement.
