• Class II malocclusion is the most prevalent type of dental malocclusion, affecting approximately 20.05% of patients. — Efficacy of anterior intrusion-based vertical control versus conventional sagittal retraction in adolescents with hyperdivergent mandibular retrognathia: study protocol for a randomised controlled trial
• In hyperdivergent skeletal class II malocclusion, the mandibular plane is steeply inclined and the occlusal plane is steep as a consequence of backward (clockwise) rotation of the mandible. — Efficacy of anterior intrusion-based vertical control versus conventional sagittal retraction in adolescents with hyperdivergent mandibular retrognathia: study protocol for a randomised controlled trial
• Hyperdivergent patients present with mandibular retrognathia accompanied by excessive anterior facial height, resulting in the long-face or adenomorphic morphology. — Efficacy of anterior intrusion-based vertical control versus conventional sagittal retraction in adolescents with hyperdivergent mandibular retrognathia: study protocol for a randomised controlled trial
• Most skeletal class II malocclusion is caused by mandibular retrognathia, not true maxillary protrusion; only about 14% involves true maxillary protrusion. — Efficacy of anterior intrusion-based vertical control versus conventional sagittal retraction in adolescents with hyperdivergent mandibular retrognathia: study protocol for a randomised controlled trial
• Vertical overeruption of the maxillary incisors is the principal cause of the steep occlusal plane in hyperdivergent adolescents. — Efficacy of anterior intrusion-based vertical control versus conventional sagittal retraction in adolescents with hyperdivergent mandibular retrognathia: study protocol for a randomised controlled trial
