Aim: To report a conservative orthodontic retreatment in a 23-year-old woman with class III malocclusion and root resorption in maxillary teeth. Background/case description: The patient was diagnosed with Angle class III subdivision malocclusion with edge-to-edge incisor bite and mild crowding of the lower anterior teeth. Treatment consisted of the use of miniplates as skeletal anchorage for distalization of mandibular teeth and no intervention in the maxilla. At debonding, the patient showed attractive dentofacial esthetics and a functional occlusion. Class I canine and molar relationship was obtained, with normal overjet and overbite. Cephalometric analysis demonstrated a retraction of the mandibular incisors and a distalization of the mandibular first molars (3 mm). One-year follow-up records exhibited stability of the treatment outcomes in the short term. Conclusion: Conservative orthodontic retreatment of a class III malocclusion associated with severe resorption of maxillary incisors was accomplished successfully using miniplates in the mandible and no appliance in the maxilla.
