title: "Biological restoration": root canal and coronal reconstruction.
abstract: Anterior tooth fracture, as a result of traumatic injuries, frequently occurs in dentistry. Proper reconstruction of extensively damaged teeth can be achieved through the fragment reattachment procedure known as "Biological Restoration." This case report refers to the esthetics and functional recovery of extensively damaged central maxillary incisors through the preparation and adhesive cementation of "Biological Posts and Crowns" in a young patient. Both biological posts and crowns--post and dental fragment obtained through natural, extracted teeth from another individual--represent a low-cost option and alternative technique for the morphofunctional recovery of extensively damaged anterior teeth.
  
  
  CONCLUSIONS
  The biological restorations are an alternative technique for reconstruction of extensively damaged teeth that provides highly functional and esthetic outcomes.
