The FIBIO aesthetic, nonmetal post is more than just a simple fiber root canal post. Made of a specially selected type of glass fiber, the mechanical and adhesive properties have been thoroughly tested to create the most effective design. This protocol allows the matching of the root anchor with the shape of the existing canal. The glass fiber used in the FIBIO is made radiopaque by the addition of zircon, which has the added advantage of enhancing the material's strength. For more information, call (800) 397-4433.
