• A 150 g intrusive force is applied via elastomeric chains and reactivated every four weeks in the test group. — Efficacy of anterior intrusion-based vertical control versus conventional sagittal retraction in adolescents with hyperdivergent mandibular retrognathia: study protocol for a randomised controlled trial
• Miniscrews are inserted bilaterally into the anterior alveolar bone distal to the canines once both arches are fully aligned and levelled. — Efficacy of anterior intrusion-based vertical control versus conventional sagittal retraction in adolescents with hyperdivergent mandibular retrognathia: study protocol for a randomised controlled trial
• The vertical control protocol uses miniscrews inserted into the maxillary anterior labial alveolar bone to apply intrusive force to the upper incisors, flattening the steep occlusal plane. — Efficacy of anterior intrusion-based vertical control versus conventional sagittal retraction in adolescents with hyperdivergent mandibular retrognathia: study protocol for a randomised controlled trial
• Occlusal plane flattening from anterior intrusion drives counterclockwise mandibular rotation, simultaneously reducing anterior face height, decreasing the ANB angle, enhancing chin prominence, and expanding the pharyngeal space. — Efficacy of anterior intrusion-based vertical control versus conventional sagittal retraction in adolescents with hyperdivergent mandibular retrognathia: study protocol for a randomised controlled trial
• Monitored adverse events for the miniscrew-based intervention include gingival erythema, swelling, hyperplasia, root resorption, and demineralisation of dental necks at miniscrew insertion sites. — Efficacy of anterior intrusion-based vertical control versus conventional sagittal retraction in adolescents with hyperdivergent mandibular retrognathia: study protocol for a randomised controlled trial
