3M ESPE’s RelyX™ fiber post is now available in an additional size. The new, smallest post “0,” with a coronal diameter of 1.1 mm, presents a beneficial addition to the portfolio. RelyX Fiber Post radiopacity was rated “Good” by a leading independent dental publication. 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. Improved radiopacity is among the highest of available glass fiber posts. RelyX™ Unicem system makes cementing a post fast, easy and reliable.
