Clinical Overview
3M RelyX™ Fiber Post is a glass fiber–reinforced composite post system designed for the reinforcement of endodontically treated teeth with insufficient remaining tooth structure. Featuring dentin-like elasticity and a tapered anatomical design, it supports even stress distribution within the root canal while minimizing the risk of root fracture. Its translucent, radiopaque structure enhances esthetics and enables effective light transmission during cementation, making it suitable for both anterior and posterior restorations.
Key Benefits
- Dentin-like elasticity: Reduces risk of root fracture by distributing functional stresses more evenly.
- High mechanical strength: Glass fiber reinforcement ensures long-term stability and fatigue resistance.
- Simplified cementation: Compatible with self-adhesive resin cements, eliminating the need for etching, priming, or bonding steps.
- Translucent design: Enhances esthetics and facilitates light curing deep within the canal.
- Tapered anatomy: Conserves dentin during preparation and improves post adaptation.
- Radiopaque material: Allows clear radiographic identification during follow-up.
- Void-reducing application: Elongation tips enable controlled cement placement from apical to coronal.
Kit Contents
- 15 fiber posts (5 each of sizes 1 – 1.3 mm, 2 – 1.6 mm, 3 – 1.9 mm)
- 4 drills (Size 1, Size 2, Size 3, Universal)
- 20 elongation tips for cement delivery
Working & Setting Times
- Working: Determined by the selected luting cement system.
- Setting: Dependent on cement type; compatible with light-, dual-, or self-cure resin cements.
Indications
- Reinforcement of endodontically treated teeth with insufficient coronal structure
- Retention and support of core build-ups
- Foundation for crowns and indirect restorations
- Anterior and posterior post-and-core restorations
Instructions for Use
- Prepare post space following endodontic treatment using corresponding drills.
- Select appropriate post size and verify fit within the canal.
- Clean and dry the canal according to adhesive protocol.
- Apply compatible resin cement into the canal using an elongation tip.
- Insert the fiber post slowly to full depth and remove excess cement.
- Light cure or allow self-cure according to cement instructions.
- Proceed with core build-up and final restoration.
Summary
3M RelyX™ Fiber Post Intro Kit 56860 provides a complete, clinically efficient solution for post-and-core procedures. With dentin-like elasticity, strong fiber reinforcement, and simplified cementation, it enhances restoration longevity while reducing procedural complexity—making it a reliable choice for restoring structurally compromised teeth.
