The next-generation zirconia glass fiber post featuring Active Adhesion System (AAS) — designed for exceptional adhesion, strength, and aesthetics.
What makes them special
Active Adhesion System (AAS)
Advanced biomimetic matrix-integrated chemistry enhances bonding with OverCEM SA self-adhesive cement — no additional silanization needed.
Optimized Geometry
Conical–cylindrical shape offers maximum coronal diameter where it exits the root canal while minimizing apical dimensions — this boosts prosthetic core stability and counteracts chewing forces.
Roughened Micro-Retentive Surface
No need for extra surface treatments — engineered roughness maximizes cement adhesion.
Zirconia Fiber Reinforcement
80% zirconia-infused glass fibers. High flexural strength (1700 MPa). Balanced modulus of elasticity (~60–70 GPa), mimicking dentin for stress distribution
Aesthetic & Radiopaque
Translucent material enhances light-transmission and cement curing, while radiopacity (~300% Al) provides clear X-ray visibility.
Long-Term Durability & Sterilization
Fatigue-tested up to 5 million cycles without failure; autoclave-safe at 135 °C/2.1 bar for 5 min with no mechanical degradation.
Clinical Advantages
• Enhanced retention & core stability due to optimized shape • Simplified protocol without silanization • Dentin-like flexibility reduces risk of root fracture • Ideal for compromised cases — maximum coronal support where needed  • Extra-fast cement polymerization thanks to translucency • Reliable removal — toughness aids retreatment when necessary
Best use cases
• Endodontically treated teeth with extensive coronal damage • Multiple posts in flared canals • Situations requiring high adhesive strength and mechanical resilience • Cases needing aesthetic integration and reliable retreatment options
Kit & Sizes
• Starter Kit 0–1–2 includes three sizes (#0, #1, #2) paired drills • Refill packs available (#0 through #3, and #4 for endodontic versions) • Color-coded post–drill system ensures intuitive use

About OverFibers Products
Why Dual-Cure Cementation Matters for Indirect Composite Restorations in Endodontically Treated Teeth
Indirect composite restorations require a luting material that combines reliable adhesion, efficient handling and predictable polymerization, even in areas where light transmission may be limited. A dual-cure resin cement offers […]
Oval Canal Reconstruction: The Hi-Rem Polygon Post Efficiency
The restorative management of endodontically treated premolars often presents a biomechanical challenge due to the prevalence of oval-shaped root canals. Traditional circular fiber posts frequently result in an excessive thickness […]
Endodontic retreatment and post endodontic restoration of a central incisor
In this case I had to retreat two badly decayed teeth. We put provisional crowns first, in order to preserve the aesthetics of the patient between treatments, then I scheduled […]
The patient, 72, had these crowns a few years earlier and had no desire to remove them. Tooth 4.5 had already been treated, but it was the only one that […]
Retreatment and post-retained restoration in a central incisor
When a tooth has undergone root canal treatment and has lost a large amount of coronal structure, the restorative challenge is not only to replace missing tissue, but to recover […]
A 47-year-old female patient presented with a structurally compromised maxillary left second premolar (tooth 25) following completed endodontic treatment. Due to the significant loss of coronal tooth structure, a post-endodontic […]
Retreatment and post endo restoration with Overfibers post
A patient came to my attention complaining about impossibility to chew on the right side of the mouth. A defective restoration was found on the first upper molar, with a […]
Endo restorative rehabilitation with fiber post of a lower premolar
In post endodontic restorations with post, the choice of the post is extremely important because we need to select the biggest post that fits into the root canal without touching […]
Comprehensive Dentistry: A Multidisciplinary Strategy for Periodontal-Endodontic Lesions and Restorative Care
The management of periodontal-endodontic lesions represents a complex clinical challenge requiring a comprehensive understanding of the interactions between the periodontium, the pulp, and restorative dental structures. These lesions often present […]
