Management of root resorption of anterior teeth caused by impacted canines with emergency traction for replacement of central incisors

Impacted maxillary canines occasionally incline mesially and cause severe root resorption of the maxillary incisors. Here, we describe a case of severe root resorption of the maxillary central incisors caused by impacted canines and the successful alignment of the maxillary arch with the replacement of the central incisors by the canines using a super-elastic Ni-Ti alloy. Furthermore, we successfully managed the patient’s psychological distress using this approach. In the future, if the lateral incisors cannot be conserved, the retracted canines will be available as abutment teeth for prosthodontic treatment.
