Introduction: The rehabilitation of patients with dental avulsion history could be complex and difficult to choose. The possibility of rehabilitation with dental implants may be considered when choosing the replantation, due to the possibility of bone tissue maintenance, especially in patients with incomplete facial growth. Objective: The purpose of this paper is to report a dental avulsion case treated by late tooth replantation, aiming at bone level maintenance for further rehabilitation with dental implant. Case Report: Male patient, 11 years old, suffered dental trauma during sports practice, resulting in tooth #21 avulsion. The tooth was found after 24 hours. The therapeutic choice was tooth replantation, although the conditions were adverse due to extraoral time (60 hours) and storage medium (dry). The tooth was cleaned, immersed in calcitonin for 15 minutes, and endodontically treated before replantation. Then, a semi-rigid splint was used for 10 days. One year after the replantation a replacement root resorption was radiographically diagnosed. After 7-year follow-up, the root was almost completely reabsorbed, with sufficient bone tissue for insertion of dental implant. The tooth remnant was removed and an immediate dental implant was performed. After 6 months, a ceramic-ceramic crown was confected.
Conclusion: Thus, the importance of avulsed tooth replantation is clear in the maintenance of bone tissue level for dental implant placement and, consequently, reestablishment of function, as of esthetic and phonetic.
