Clinical Overview
3M™ RelyX™ Fiber Post 3D Intro Kit (56957) is a comprehensive post-and-core restorative system designed for the reconstruction of endodontically treated teeth with insufficient remaining coronal structure. The system features glass-fiber reinforced posts with a unique 3D macro-retentive design that enhances mechanical retention for core build-up materials. Its microporous surface promotes strong bonding within the root canal without requiring additional surface treatment, while dentin-like elasticity helps distribute functional forces and reduce the risk of root fracture.
Key Benefits
- 3D macro-retention design: Coronal retention features improve mechanical retention with core build-up materials.
- Microporous bonding surface: Promotes strong adhesion within the root canal without the need for silanization.
- Dentin-like elasticity: Helps distribute occlusal forces and reduces the risk of root fracture.
- High radiopacity: Enhances radiographic visibility for accurate post positioning.
- Color-coded system: Posts and drills correspond by size for simplified clinical selection.
- Esthetic alternative to metal posts: Glass fiber construction provides translucency suitable for aesthetic restorations.
Kit Contents
- 20 RelyX Fiber Post 3D glass fiber posts (5 each of sizes 0, 1, 2, and 3)

Instructions for Use
- Remove gutta-percha from the root canal to the desired depth.
- Select the drill corresponding to the chosen fiber post size.
- Prepare the canal carefully using the designated drill.
- Clean and dry the prepared canal.
- Apply a compatible resin cement inside the canal.
- Insert the RelyX Fiber Post to the required depth.
- Build up the core material and proceed with the final restoration.
Summary
