Fiber Post

Dental Fiber Posts

In modern endodontic-restorative practice, fiber posts have largely replaced cast and pre-fabricated metal posts as the routine intracanal-retention choice for the post-and-core build-up following root canal therapy. Their dentine-matched modulus of elasticity, bondability with resin cement and tooth-coloured aesthetics suit anterior, premolar and molar reconstruction alike, with vertical-root-fracture rates significantly lower than metal alternatives. Dentalkart stocks the Hahnenkratt Contec Blanco Fiber Post + Drill alongside fiber post systems from Angelus, Waldent, Superendo and AAA, trusted by 50,000+ dentists across 110000+ Indian pincodes.

Fiber Post Selection by Clinical Indication

Anterior Crown Reconstruction

For anterior crown reconstruction where aesthetics dominate, translucent glass-fibre posts such as the AAA Fiber Post (Pack of 10) allow light transmission through the post body, supporting a translucent dual-cure cement layer and a natural-looking porcelain or composite veneer build-up that avoids the grey shine-through associated with metal posts.

Posterior Molar & Premolar Reconstruction

For posterior molars and premolars under heavy occlusal load, higher-strength carbon-fibre options such as Angelus Reforpost Carbon Fiber offer greater flexural strength than translucent glass-fibre alternatives, suiting the bulk-load demands of bruxism patients and full-coverage molar crown work.

Re-treatment-Ready Restoration

For cases at elevated risk of endodontic re-treatment — patients with high caries indices, residual periapical pathology or specific medico-legal documentation requirements — the Waldent Radiopaque Composite Fiber Post shows clearly on follow-up periapical and bite-wing radiographs, simplifying future canal-access planning and post-removal.

Starter Kits with Matched Calibrated Drills

For clinics adopting fiber-post protocols for the first time and prosthodontic-heavy practices wanting consistent passive fit across cases, all-in-one starter sets such as the Superendo Super Fiber Post Kit bundle posts and calibrated parallel-sided or tapered drills sized to the exact diameter of each post for a guaranteed passive fit.

The Post-and-Core Workflow Step by Step

After confirming the apical seal of completed root canal therapy, post-space preparation begins by removing 4–5 mm of gutta-percha apically (leaving an apical seal), calibrating the canal with the matched fiber-post drill, etching the canal-wall dentine with phosphoric acid, applying a dentine bonding agent, dispensing dual-cure resin cement into the canal, seating the fiber post passively and light-curing through the translucent post body. The exposed coronal post-stub is then built up with composite or dual-cure core material before crown preparation in the same or a subsequent visit.

How to Match a Fiber Post to Canal Anatomy

Match the post diameter to the largest passive fit achievable without further dentine removal — over-sizing the post space weakens radicular dentine and increases vertical-fracture risk far more than under-sizing the post does. Tapered posts suit naturally tapered canals (commonly anterior teeth) while parallel-sided posts engage straight middle-third dentine more uniformly. For curved canals, avoid forcing a straight post past the apical curvature; use a shorter post and rely on the core build-up plus a ferrule for retention instead.

Brands of Fiber Posts at Dentalkart

Hahnenkratt (Germany) leads the catalogue with the Contec Blanco Fiber Post + Drill system, an established European prosthodontic standard. Angelus (Brazil) supplies Reforpost Carbon Fiber for high-load posterior cases. Waldent contributes the Radiopaque Composite Fiber Post for follow-up-visible cementation. Superendo's Super Fiber Post Kit gives clinics a complete starter bundle with matched drills. AAA Fiber Posts in 10-piece bulk packs offer an economy translucent glass-fibre option for high-volume general practice.

Why Buy Fiber Posts from Dentalkart

Dentalkart supplies fiber posts directly from authorised manufacturers including Hahnenkratt, Angelus and Waldent, with batch-coded packaging, cash-on-delivery, GST invoices and 110000+ pincode coverage across India. Practices ordering fiber-post systems get matched calibrated drills, dual-cure cement-compatible designs and clear post-cementation radiographic verification, all in a single bulk order ready for the next post-and-core appointment.

How long do fiber posts last in clinical service?

Fiber posts last for the full clinical lifespan of the post-and-core restoration — typically 10–15 years or longer when cemented with a dual-cure resin cement and protected by a well-fitting full-coverage crown with an intact ferrule. Long-term clinical studies show failure rates significantly lower than cast metal posts, with the most common failure mode being post-debonding (recoverable) rather than catastrophic root fracture.

When is a fiber post contraindicated?

A fiber post is contraindicated when sufficient coronal dentine remains for a direct core build-up alone, in canals too narrow to accommodate the smallest matched drill safely, in cases with active periapical infection requiring re-treatment first, and in immature open-apex teeth where canal anatomy does not support standard post placement. In these scenarios a direct composite build-up or alternative retentive approach is preferred.

How does post diameter affect root fracture risk?

Post diameter is a major determinant of vertical root fracture risk because over-sizing the post space removes radicular dentine that the tooth needs for structural integrity, while a larger post does not improve retention proportionally. The clinical principle is to match the post to the largest size achievable with passive fit and no additional dentine removal, preserving as much radicular wall thickness as possible.

Can fiber posts be used in primary (deciduous) teeth?

Fiber posts are not routinely used in primary teeth because deciduous tooth roots are short, conical and undergo physiological resorption ahead of permanent-tooth eruption. For pulpally compromised primary molars after pulpectomy, intracanal retention is usually achieved with composite or zinc oxide eugenol packed directly into the canal and a stainless-steel crown placed coronally — fiber posts are reserved for permanent dentition.

Do fiber posts require a ferrule on the remaining tooth structure?

Fiber posts require a ferrule of at least 1.5–2 mm of circumferential coronal dentine above the crown margin to deliver predictable long-term success. The ferrule is a stress-distribution mechanism where the crown engages residual tooth structure independently of the post-and-core, sharply reducing load transferred to the post-cement-dentine interface and preventing catastrophic post debonding under heavy occlusal force.
