• Mandibular retrognathia is a recognised risk factor for obstructive sleep apnoea, with documented consequences for maxillofacial development and psychological wellbeing in children and 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
• During open-mouth breathing, posterior teeth lose occlusal contact, promoting excessive posterior tooth eruption and backward-downward mandibular rotation that reinforces the long-face pattern in a self-perpetuating cycle. — Efficacy of anterior intrusion-based vertical control versus conventional sagittal retraction in adolescents with hyperdivergent mandibular retrognathia: study protocol for a randomised controlled trial
• Adolescents with a vertical skeletal growth pattern have a significantly narrower nasopharyngeal airway than those with a normal growth pattern. — Efficacy of anterior intrusion-based vertical control versus conventional sagittal retraction in adolescents with hyperdivergent mandibular retrognathia: study protocol for a randomised controlled trial
• Sagittal retraction alone without levelling the occlusal plane can increase the risk of upper airway stenosis and produce a double retrognathic profile. — Efficacy of anterior intrusion-based vertical control versus conventional sagittal retraction in adolescents with hyperdivergent mandibular retrognathia: study protocol for a randomised controlled trial
• Prolonged open-mouth breathing alters tongue posture, disrupting the force balance between inner and outer dental arch surfaces and causing progressive narrowing of the upper arch. — Efficacy of anterior intrusion-based vertical control versus conventional sagittal retraction in adolescents with hyperdivergent mandibular retrognathia: study protocol for a randomised controlled trial
