Post & Core

Post & Core: Fiber Posts, Metal Posts and Core Build-Up Materials for Endodontic Restoration

Post & core is the two-stage foundation restoration for an endodontically treated tooth — a fiber, quartz or metal post is cemented into the prepared root canal, then a dual-cure or light-cure composite core build-up is sculpted around the post coronally to recreate dentin volume and support the final crown. Dentalkart stocks fiber posts, metal self-posts and core build-up resins from Voco Rebilda DC, Prime Dental Restorite, AAA, Superendo, Medicept, Angelus and generic Chinese fiber post systems.

Types of Post & Core Materials

Glass / quartz fiber posts

Translucent fiber-reinforced epoxy posts with elastic modulus similar to dentin — the modern default for anterior aesthetic restorations and most posterior cases. For example, AAA Dental Fiber Post Kit (20 posts + 4 drills).

Metal screw posts

Stainless-steel or titanium self-threading screw posts that engage canal dentine actively — reserved for severely broken-down teeth where maximum retention is needed.

Branded fiber post systems (Angelus Reforpost)

Premium branded fiber post systems with calibrated matched drills, length markings and bonded-post protocols — for example, Angelus Reforpost Key.

Dual-cure core build-up resin

Self-mixing dual-cure composite resin from a 1:1 cartridge — packs and cuts like a regular composite but sets even in the dark depths around a fiber post, eliminating uncured material under the crown. For example, Voco Rebilda DC Set Refills.

Light-cure core build-up composite

Flowable or condensable light-cure composite for incremental core build-up where light access is good — for example, Prime Dental Restorite Core Build-Up.

When Post & Core Is Used

• Endodontically treated teeth with less than 50% remaining crown structure
• Anterior crowns and bridge abutments needing core retention
• Posterior crown preparation after extensive caries removal
• Re-cementation of dislodged crowns where remaining tooth height is insufficient
• Pediatric anterior aesthetic restoration after pulpectomy (fiber posts only)
• Implant-supported overdentures requiring custom post-and-core abutments

How to Plan a Post & Core Restoration

1. Verify good apical seal — leave 4–5 mm gutta-percha at the apex before post space preparation.
2. Choose fiber post over metal whenever possible — fiber matches dentin elastic modulus and reduces vertical root fracture risk.
3. Match post diameter to apical third of the canal; over-prepared canals weaken the root.
4. Bond the post with dual-cure resin cement and a silanated post surface for maximum push-out strength.
5. Use dual-cure core build-up (Voco Rebilda DC) when access is limited — it sets in the dark and eliminates uncured zones.
6. Leave at least 1.5–2 mm of ferrule height on remaining tooth structure for crown retention and biomechanical stability.

What is the difference between a post and a core build-up?

The difference between a post and a core build-up is structural role. The post is a fiber or metal rod cemented into the prepared root canal to retain the core. The core is a dual-cure or light-cure composite resin sculpted around the post coronally to recreate the missing dentin volume and provide a stable base for the final crown preparation.

What is a dual-cure core build-up resin?

A dual-cure core build-up resin is a self-mixing composite resin from a 1:1 cartridge that polymerises by both chemical (auto) and light activation. It sets even in the dark depths around a fiber post where curing-light access is blocked, eliminating uncured material under the final crown that would otherwise leak and fail.

When do I need a post and core instead of just a core?

You need a post and core instead of just a core when the endodontically treated tooth has less than 50% remaining crown structure or insufficient height for crown retention. With more remaining structure, a direct composite core bonded to dentin is enough — the post is added only when the core itself needs anchorage in the root canal.

Can I use fiber posts in pediatric pulpectomy teeth?

Yes, you can use fiber posts in pediatric pulpectomy teeth for anterior aesthetic strip-crown restoration. Translucent glass/quartz fiber posts cut easily, can be shortened intra-orally, and match the natural tooth shade under composite strip crowns. Metal posts are avoided in primary teeth because of root-resorption interference and aesthetic compromise.

Are the post & core materials on Dentalkart genuine?

Yes, every post and core material on Dentalkart is genuine. All Voco, Prime Dental, AAA, Superendo, Medicept and Angelus posts, fiber post kits and core build-up resins are sourced direct from the manufacturer or authorised Indian distributor and ship in sealed sterile packs with original lot number and expiry on every box.
