Description
Product Overview
The 3M ESPE Relyx Fiber Post Refill is a premium dental post designed to restore structural integrity to endodontically treated teeth. Manufactured by 3M Company, a global leader in advanced materials, this post combines a high‑performance resin matrix with uniformly distributed parallel glass fibers, delivering a balance of strength and flexibility that mimics natural dentin.
Unique to the Relyx line, the resin composition incorporates a proprietary blend of monomers that polymerize efficiently under standard dental curing lights. The evenly dispersed fibers create a continuous load‑bearing network, reducing the risk of fracture under functional stresses. This architecture also promotes even stress distribution along the root canal, enhancing long‑term durability.
Complementing the fiber reinforcement, the post features a microporous surface that encourages micro‑retentive bonding. The microscopic pores increase the surface area available for adhesive interaction, resulting in a stronger, more reliable bond between the post and the root canal dentin. This design also facilitates deeper light penetration, ensuring complete polymerization of the resin throughout the canal.
Package dimensions are compact at 1 × 1 × 1 inches and weigh only 1.6 ounces, making storage and handling straightforward for dental practices. The product is identified by model number 3M‑56872 and has been available since July 5 2018, reflecting a proven track record in the professional dental market.

Usage
This fiber post refill is intended for use by qualified dental professionals during post‑and‑core procedures following root canal therapy. It is suitable for single‑rooted teeth where a high level of mechanical reinforcement is required, such as premolars and molars that will support definitive restorations like crowns or bridges.
Clinicians can apply the post after thorough canal cleaning and shaping, using a compatible adhesive system to maximize the benefits of the microporous surface. The post’s translucency allows for efficient light curing, reducing chair‑time and improving patient comfort. Its design accommodates standard post‑space preparation techniques, ensuring a predictable fit and ease of placement.
Because the post is compatible with a wide range of resin cements, it integrates seamlessly into existing clinical workflows. Whether used in a private practice or a larger institutional setting, the Relyx Fiber Post Refill supports consistent outcomes across diverse case scenarios.

FAQ
What is the recommended curing time for this post?
For optimal polymerization, we recommend a minimum of 20 seconds of light exposure using a curing unit with an output of at least 1000 mW/cm². Extending the curing time to 30 seconds can further ensure complete conversion, especially in deeper canal sections.
Can this post be used with any adhesive system?
The Relyx Fiber Post Refill is compatible with most dual‑cure and light‑cure resin cements approved for endodontic use. However, for best results, we suggest using adhesives that contain a functional monomer such as 10‑MDP, which interacts favorably with the microporous surface.
What size does the post come in?
This refill is supplied as a single post with a standard diameter of 1.2 mm and a length of 14 mm, matching the dimensions of the original Relyx Fiber Post system. The size is suitable for most single‑rooted teeth requiring post placement.
How does the microporous surface improve bonding?
The microporous surface creates microscopic channels that increase the surface area available for adhesive infiltration. This micro‑retentive effect promotes mechanical interlocking of the resin cement, resulting in higher bond strength and reduced risk of debonding under functional loads.
Is there a warranty or guarantee for this product?
3M provides a limited warranty that covers manufacturing defects for a period of one year from the date of purchase. Should any issues arise related to product quality, our customer service team will work with you to resolve the matter promptly.
