is a fibre reinforced composite designed for use as a replacement of dentin. The short fibres prevent and stop the advance of fracture in the restoration. A resistance to fractures equivalent to that of dentin and two times higher than any composite provides incomparable resistance in restoration. Minimum horizontal contraction, since the fibres contribute to reducing shrinkage in the direction they face. Increases from 4 to 5 mm can be polymerised in block. Safe adhesion to the coating composite and tooth substance.
