Introduction: Ideal coronal reconstruction of a fractured tooth is still a challenge for restorative dentistry. While there are many post systems on the market, none of them fully satisfies all necessary mechanical and biological requirements. Biological posts could be a useful substitute for traditional post systems
Objectives: Proper reconstruction of extensively damaged teeth can be achieved through the fragment reattachment procedure known as “biological restoration.”
Methods: A 32-year-old woman in this case study complained of a cracked crown in her right maxillary central incisor. A broken maxillary right central incisor with considerable tooth structural loss that extended into the cervical third of both the crown and root was revealed by clinical and radiographic investigations. The maxillary central incisor that had been endodontically treated for fracture required strengthening using a "Biological post." In this instance, a dentinal post was prepared using a recently extracted human maxillary cuspid, and it was then confirmed into the post space and bonded with dual cure resin cement, followed by core build up and prosthesis placement.
Results: Biological post obtained through extracted teeth from another individual–represent a low‑cost option and alternative technique for the morphofunctional recovery of extensively damaged anterior teeth, satisfying most of the mechanical as well as biological needs.
Conclusions: Since biological dentin posts offer superior adhesion, strength and retain internal dentin walls, they can be regarded as a good substitute for traditional post systems. This is because they closely resemble the structure found in natural teeth.
