RelyX™ Fiber Post: A new family member is welcomed

New post size to complement existing line of products, ensuring reliable clinical performance

ST. PAUL, Minn. – (March 10, 2010) – As of mid-March 2010, RelyX™ Fiber Post will be available in an additional size. The new, smallest post “0”, with a coronal diameter of 1.1 mm, presents a beneficial addition to the existing portfolio. RelyX™ Fiber Post radiopacity was rated “Good” by a leading independent dental publication. RelyX™ Fiber Posts are a reliable, esthetic and convenient solution standing for predictable clinical performance.

In contrast to metal posts, root canal posts made of glass fibers embedded into a resin matrix -- such as RelyX™ Fiber Post by 3M ESPE -- offer an esthetic solution for all-ceramic restorations. Due to their high translucency and an appearance similar to that of tooth structure, RelyX™ Fiber Posts are not visible through the restoration – unlike the dark shadow often caused by metal posts – and support a natural light reflection.

However, the similarity between RelyX™ Fiber Posts and natural teeth not only exists in terms of appearance: Their mechanical properties are related as well, ensuring reliable clinical performance. Since the modulus of elasticity is in the same range as that of dentin, forces are distributed evenly within the tooth and thus, the “wedge effect” characteristic of metal posts( i.e., occurring peak forces that may lead to root fracture) is avoided. The tapered shape of RelyX™ Fiber Post further helps to conserve valuable root canal dentin.

In order to make these benefits available for all clinical situations, 3M ESPE will offer the new post size “0” in mid-March 2010. With a coronal diameter of 1.1 mm, it will complement the existing sizes of 1.9 mm, 1.6 mm and 1.3 mm diameter very well. For the required adhesive cementation of the posts, a brilliant solution is provided: RelyX™ Unicem Self-Adhesive Universal Resin Cement eliminates the need for prior etching, priming and bonding as well as the necessity to prime and silanize the post. Since the material is available with the RelyX™ Unicem Aplicap™ Elongation Tip designed to reach into the root canal, cement application from bottom to top is simplified and the risk of cement voids is virtually eliminated.

With the useful addition to the popular RelyX™ Fiber Post System, 3M ESPE makes sure that users can rely on convenience and excellent clinical performance in every situation.
