RelyX™ Fiber Post
RelyX™ Unicem Self-Adhesive Universal Resin Cement

The stronger yet simpler solution for cementing a post.
More than a post alone, RelyX™ Fiber Post from 3M ESPE is a complete system, designed to make excellent clinical results easier to achieve.

RelyX Fiber Post offers long-term safety and stability.

Greater elasticity

RelyX Fiber Post has elasticity similar to dentin than do metal and ceramic posts – so there’s a lower risk of root fracture due to the "wedge effect."

There is no risk of corrosion that can occur with metal posts. RelyX Fiber Post offers greater fatigue resistance than competing brands of fiber posts.

The Fatigue Test proves it!
RelyX Fiber Post shows excellent fatigue resistance — the test was stopped after 5 million cycles with no RelyX fiber post failures. [Source: 3M internal data and preliminary results of external in vitro study (M. Ferrari, University of Siena, Italy)]

RelyX™ Unicem cement gives you confidence that your permanent restorations will stay permanent.

RelyX Unicem cement offers proven optimal bonding strength with less prep work. With RelyX Unicem cement, there is no need to etch, prime or bond. Its proven performance is backed by more than 60 studies and third-party endorsements.

RelyX™ Unicem Aplicap™ Elongation Tip makes cementation faster, easier and more reliable.

End the frustration and uncertainty often experienced when cement posts when you use the RelyX Unicem Aplicap™ Elongation Tip. This specialized application tip is designed to reach into the root canal. Because you can fill the root canal from bottom to top, you reduce the chance of cement voids that can compromise bond strength.

These SEM images show a cross-section and side view of a simulated root canal that was filled with RelyX Unicem cement using the new Elongation Tip.

These SEM images of a simulated root canal show the difference.

The image above shows a simulated root canal where resin cement was applied using a common method of putting the cement directly onto the post before placement. Voids are visible as dark spots in both the cross-section and side view, potentially compromising the strength of the bond.
