🚫 Post and Core Restorations: Strengthening Severely Damaged Teeth
Post and core restorations are critical procedures in restorative dentistry, especially when managing teeth that have suffered extensive structural loss due to caries, fractures, or repeated restorative cycles. After endodontic treatment, many teeth are left with insufficient coronal dentin to support a definitive crown. Post and core systems provide the internal support and external buildup required to restore both function and aesthetics.
🔳 A post is placed inside the prepared root canal to retain the restoration, while the core reconstructs the lost coronal structure, creating an ideal foundation for a full-coverage crown. Modern posts—whether fiberglass, carbon fiber, or metal—are chosen based on case requirements such as root thickness, occlusal load, esthetic demands, and long-term prognosis.
☑️ Fiberglass posts have become highly popular due to their elastic modulus similar to dentin, reducing the risk of root fractures. When paired with adhesive luting cements and reinforced composite cores, they offer predictable strength, excellent integration, and superior esthetics for anterior and posterior teeth.
A properly executed post and core restoration ensures:
◽️ Improved retention and stability of the final crown
◽️ Better distribution of occlusal forces along the root
◽️ Reduced likelihood of catastrophic fractures
◽️ Long-term functional success in compromised teeth
👉 Ultimately, post and core restorations allow clinicians to save teeth that would otherwise be considered non-restorable, restoring both the integrity and longevity of the dentition.
