Delayed replantation of avulsed teeth with 8-hour extra oral time

Introduction: Dental avulsion is defined as a complete removal of tooth from the alveolar socket resulting in the complete disruption of blood supply to the pulp. Dental replantation is indicated for avulsed teeth with viable and aseptic periodontal ligament cells. Replantation is associated with the insertion and temporary fixation of avulsed teeth and aims to prevent tooth loss, so the function and aesthetic value of the tooth can be maintained as well as the height of alveolar ridges. Case report: A 9-year-old male patient with the chief complaint of the first maxillary incisor having been released due to a fall. The avulsed tooth was carefully replanted in its original position after an extra oral root canal treatment, and a semi rigid splinting was consequently performed using the Ivy eyelet wiring ligation technique. Conclusion: The risk of root resorption in replantation case is relatively high and relays on the clinical conditions of the periodontal ligament, apical foramen closure, duration of extra oral time and the age of patient.
