A woman, aged 24 years and 8 months, had a convex profile, which she desired to improve. She was diagnosed with a skeletal Class II jaw-base relationship with a high mandibular plane angle. After extraction of four premolars, three miniscrews were implanted at the median palatine suture and the distal alveolus of the maxillary lateral incisors. Anterior rotation of the mandible was achieved by intrusion of the entire maxillary arch. The total active treatment period was 32 months. Acceptable occlusion and an improved facial profile were maintained after 29 months of retention.
