Consist of strong fiber bundles braided in a multi-axial arrangement. Both posts are non-corrosive, biocompatible and offer superior resistance to bending and torsion forces. Virtually unbreakable. Elasticity is similar to dentin, enabling the posts to flex with the natural dentin. Dissipate occlusal stress and do not transmit it as metal posts do. Provides superior resistanceto bending and torsion forces compared to fibers in an ordinary axially parallel arrangement. Also offers passive retention slots instead of active cutting threads.
