Incisor torque recovery in a transfer case with iatrogenic perforation of the labial cortical plate

This report presents an orthodontic retreatment of a patient seeking a second opinion because of severe retroclination of the maxillary incisors and anterior crossbite. Perforation of the labial cortical plate by the roots of the maxillary incisors was noted. The patient declined a surgical approach, so skeletal anchorage was planned to regain the incisor torque and improve the facial profile. The orthodontic treatment successfully repositioned the maxillary incisor roots within the alveolar bone. The facial profile was improved significantly through active vertical control. This report emphasizes the significance of torque control during space closure and the potential for active vertical control to enhance the profile. Overall, treatment stability was good after 1 year of retention.
