Rehabilitation of a mutilated maxillary central incisor using autogenous dentin post.

Ideal coronal restoration that provides satisfactory esthetic and functional outcome for endodontically treated and extensively damaged teeth is still an arduous task for restorative dentistry. None of the available post systems have all the ideal biological and mechanical properties. Biological dentin posts are considered as a good alternative to conventional post systems as they preserve dentin walls, which results in better distribution of forces along the root surfaces in the compromised tooth. This case report is an attempt to detail "autogenous dentin post" which serves as a homologous unit for the reinforcement of endodontically treated tooth by virtue of its biomimetic property.
