Fiber Posts

Dental Fiber Posts

Dental fiber posts are pre-fabricated tooth-coloured intracanal posts made from glass-fibre or carbon-fibre reinforced epoxy resin, cemented into the prepared root canal of an endodontically treated tooth to retain a coronal core build-up before crown preparation. Their modulus of elasticity is closer to dentine than metal posts, reducing the risk of vertical root fracture and allowing translucent light transmission for aesthetic anterior cases. Dentalkart stocks the Hahnenkratt Contec Blanco Fiber Post + Drill alongside post systems from Angelus, Waldent, Superendo and AAA, trusted by 50,000+ dentists across 110000+ Indian pincodes.

Types of Dental Fiber Posts

Glass-Fibre Posts

Translucent glass-fibre posts such as the AAA Fiber Post (Pack of 10) transmit light through the post body, enabling complete polymerisation of dual-cure resin cement along the entire canal length and supporting an aesthetic translucent build-up for anterior crowns and veneers.

Carbon-Fibre Posts

Carbon-fibre posts such as the Angelus Reforpost Carbon Fiber offer higher flexural strength than glass-fibre alternatives, suiting posterior molar and premolar cases where mechanical loading is the dominant requirement and aesthetic translucency is not critical.

Radiopaque Composite Fiber Posts

Radiopaque composite fiber posts including the Waldent Radiopaque Composite Fiber Post show clearly on follow-up periapical and bite-wing radiographs, simplifying post-cementation verification and any future re-treatment planning.

Post + Drill Kits

Matched post-and-drill kits include a calibrated parallel-sided or tapered drill set to the exact diameter of the corresponding fiber post, guaranteeing a passive intracanal fit, minimal dentine removal and a uniform cement film thickness.

When Are Fiber Posts Used?

Fiber posts are used when an endodontically treated tooth has lost significant coronal structure and the remaining dentine is insufficient to retain a core build-up alone. Indications include extensively broken-down anterior crowns, cracked molars after root-canal therapy and structurally compromised premolars scheduled for full-coverage crown restoration where the post adds intracanal retention without the dentine-stress profile of a cast or pre-fabricated metal post.

How to Choose the Right Fiber Post

Pick glass-fibre posts for anterior aesthetic cases and any restoration where light transmission through the post body assists dual-cure cement polymerisation. Choose carbon-fibre posts for high-load posterior cases where flexural strength outweighs aesthetic translucency. Prefer radiopaque composite posts when follow-up radiographic verification is clinically important. Always size the post diameter to the smallest one that achieves passive fit with the matched drill, preserving radicular dentine and minimising vertical-fracture risk.

What is a dental fiber post?

A dental fiber post is a pre-fabricated tooth-coloured intracanal post made from glass-fibre or carbon-fibre reinforced epoxy resin, cemented into the prepared root canal of an endodontically treated tooth to retain a coronal core build-up before full-coverage crown preparation. Fiber posts replace traditional metal posts in most modern endodontic-restorative protocols.

What is the difference between glass and carbon fiber posts?

The difference between glass and carbon fiber posts is translucency and flexural strength: glass-fibre posts are translucent, allowing light transmission for dual-cure cement polymerisation and aesthetic anterior cases, while carbon-fibre posts are opaque and offer higher flexural strength for posterior molar and premolar cases where mechanical loading is the dominant requirement.

Why are fiber posts preferred over metal posts?

Fiber posts are preferred over metal posts because their modulus of elasticity is closer to dentine, reducing dentine stress concentration and the risk of catastrophic vertical root fracture during occlusal loading. They are also tooth-coloured (supporting aesthetic translucent build-ups), bondable with resin cement and easier to remove during endodontic re-treatment than cast or pre-fabricated metal posts.

How is a fiber post cemented into the canal?

A fiber post is cemented into the canal by first preparing the post space with the matched calibrated drill, irrigating with sodium hypochlorite and saline, drying with paper points, applying a dentine bonding agent into the canal walls, dispensing dual-cure resin cement into the canal, seating the post passively and light-curing through the translucent post body for glass-fibre systems.

Should a radiopaque fiber post be used?

A radiopaque fiber post should be used when follow-up radiographic verification of post position and length is clinically important — for medico-legal documentation, for cases at higher risk of re-treatment and for general endodontic-restorative workflows where the operator wants the post to be clearly visible on periapical and bite-wing follow-up radiographs.
