Strong and long-lasting RelyX™ Fiber Posts are designed to make excellent clinical results easy to achieve. Elasticity of RelyX Fiber Post is similar to human dentin for a lower risk of root fracture due to the "wedge effect". Unique resin composition and equally dispersed parallel fibers lead to superior mechanical strength. Microporous surface allows for additional bond strength through microretentive effects. Excellent light translucency for efficient light cure deep into the root canal. Suggested Application: Supporting and securing coronal restorations in cases with insufficient residual tooth structure.
