Posts & Drills

Dental Posts and Drills for Endodontically Treated Tooth Restoration

Dental posts are tapered or parallel-sided endodontic posts — glass fiber, quartz fiber or metal — cemented into a prepared root canal of an endodontically treated tooth to retain the core build-up that supports the final crown. Dentalkart stocks glass fiber post kits, metal self-screw posts, post drills, and post-removal accessories from AAA, Superendo, Medicept, Angelus, Viva and generic Chinese fiber post systems.

Types of Dental Posts and Drills

Glass fiber posts (tooth-coloured, translucent)

Translucent quartz/glass-fibre-reinforced epoxy posts with elastic modulus similar to dentin — the modern default for anterior aesthetic restorations and posterior crown build-ups. For example, AAA Dental Fiber Post Kit (20 posts + 4 drills) or Superendo Super Fiber Post Kit.

Metal screw posts (active and passive)

Stainless-steel or titanium screw-type posts that engage canal dentine actively — used when extra retention is needed in severely broken-down teeth. For example, Medicept Self Post.

Branded fiber post systems (Angelus Reforpost)

Branded translucent fiber posts with calibrated matched drills and depth markings — Angelus Reforpost Key is a widely-used Brazilian system with conical-cylindrical shape for predictable canal seating, for example, Angelus Reforpost Key.

Post drills and post-prep kits

Matched-diameter rotary drills (typically 3–4 sizes per kit) for shaping the canal to receive the post — supplied as kits with the posts or as standalone drill kits like Viva Drills Kit.

When Dental Posts Are Used

• Endodontically treated teeth with extensive crown destruction (less than 50% remaining)
• Anterior crowns and bridge abutments needing core retention
• Posterior molars with single-canal post placement for crown retention
• Re-cementation of dislodged crowns where remaining tooth structure is insufficient
• Pediatric anterior restorations after pulpectomy (fiber posts only)
• Cast post fabrication (with post-pattern resin and indirect casting)

How to Choose the Right Dental Post

1. Pick translucent glass/quartz fiber posts as the default for anterior and most posterior teeth — elastic modulus matches dentin, reducing root-fracture risk.
2. Reserve metal screw posts for severely compromised teeth that need maximum retention; counsel patient on root-fracture risk.
3. Match post diameter to the apical 1/3 of the canal — leave 4–5 mm gutta-percha for apical seal.
4. Use matched-diameter brand drills only — mixed brands change post seating and cement gap.
5. Bond fiber posts with dual-cure resin cement and a silanated post surface for maximum push-out strength.
6. Verify post length is 2/3 of root length or equal to crown height, whichever is shorter.

What are dental posts used for?

Dental posts are used to retain the core build-up in an endodontically treated tooth with less than 50% remaining crown structure. The post is cemented into the prepared root canal, the core is built on top, and the final crown sits over the core — restoring function on a tooth that wouldn't hold a crown otherwise.

What is the difference between fiber posts and metal posts?

The difference between fiber posts and metal posts is elastic modulus and root-fracture risk. Glass/quartz fiber posts have an elastic modulus close to dentin, distributing load evenly and reducing vertical root fracture. Metal screw posts are stiffer, retain better in severely broken-down teeth, but carry higher root-fracture risk and lack translucency for anterior aesthetics.

Which fiber post is best for anterior teeth?

The best fiber post for anterior teeth is a translucent quartz or glass fiber post like AAA Dental Fiber Post or Angelus Reforpost Key. Translucency lets the natural tooth and ceramic crown shade come through, avoiding the grey shadow seen with metal posts. The dentin-like elastic modulus also reduces root-fracture risk under occlusal load.

Do I need a separate drill kit with fiber posts?

Yes, you need matched-diameter drills with fiber posts to shape the canal to receive the post precisely. Most fiber post kits ship with 3–4 matched drills covering the standard post sizes. Use only the manufacturer's drills — mixed brand drills change post seating, cement gap and retention. Standalone drill kits like Viva Drills cover replacements.

Are the dental posts on Dentalkart genuine and sterile?

Yes, every dental post on Dentalkart is genuine and sterile. All AAA, Superendo, Medicept, Angelus, Viva and Chinese fiber post systems are sourced direct from the manufacturer or authorised Indian distributor and ship in sealed sterile primary packaging with the original lot number and expiry printed on every box.
