Replantation and transplantation following avulsion of two maxillary incisors

Abstract

Here we describe replantation and transplantation as a treatment conducted in a 16-year-old patient following a bicycle accident. An avulsed left central incisor in maxilla was replanted after extra-oral root canal treatment, and the lost right central incisor of the maxilla was replaced by a left lateral incisor of the mandible in the region of the fracture fissure. Follow-up examination at 34 months showed validity of treatment, although slight evidence of replacement resorption in the transplanted and replanted teeth was revealed.

Replantation after traumatic avulsion

“…[3][4][5][6][7] The outcome and success rate of the replantation depend on many factors such as status of avulsed tooth, root development stage, dryness in extra-alveoler period, storage environment, the treatment time and modality. [10][11][12][13] Storing the tooth in a physiological medium (saline e.g.,) until replantation for a short period is accepted as a well application. [2,14] It is necessary to splint the replanted tooth to the adjacent teeth flexibly during 7-10 days for periodontal healing and then to perform root canal treatment to prevent the inflammatory root resorption in cases with closed apex.…”

Root formation of an autotransplanted tooth

“…In young patients, autotransplantation may allow bone development, provide proprioceptive stimulation reestablishing a normal alveolar process (17)(18)(19).…”
