title: Complete replacement resorption after replantation of maxillary incisors: report of case.
abstract: This article describes the treatment of a 17-year-old patient with complete root resorption of the maxillary permanent central and lateral incisors following avulsion and replantation seven years ago. The most important factor influencing the prognosis of replanted teeth is the status of the periodontal ligament (PDL). As a result of replantation, the PDL cells necrosed and tooth replacement resorption occurred. The main factors, which affected the resorption after replantation and survival of PDL cells, could be summarize as; dry extraoral time greater than 30 minutes, the kept tooth in a dry environment, touching the cementum surface, and splint treatment for a prolonged time. Since complete root resorption was found in our case, these factors probably also occurred.
