title: Nonsurgical class iii orthodontic treatment.
abstract: 1. Lower incisor angle was decreased due to the closing of the extraction sites and tipping of the incisors. 2. Maxillary incisor angle was increased. 3. Maxillary arch expansion was maintained. 4. The buccal segments remained in Class III occlusion. 5. Rotation of the mandible during treatment recovered as shown by the almost parallel lower borders of the mandible on the composite cephalometric tracing of the initial and final cephalograms. 6. Facial profile did improve. 7. The dental compensations were increased as the facial contour improved, however, most Class III characteristics are still present. 8. Periodontal tissues appear to be acceptable. 9. In select Class III malocclusions orthodontic treatment alone can accomplish an acceptable result without submitting the patient to surgical procedures.
