There were any postoperative complications until the finish of orthodontic expansion process. However, in the 30th postoperative day, patient mentioned pain in upper central incisor. Periapical radiography evidenced a root fracture of central upper right incisor. After endodontic treatment, the fractured apex was removed. After 3 years of follow-up, the patient finished orthodontics, and the damaged tooth was in good aspect. Apical fracture is an unexpected complication of SARME. However, follow-up and correct treatment lead to a good prognosis for tooth maintenance. © 2018 by Mutaz B. Habal, MD.
