Comparative Evaluation of Skeletal, Dentoalveolar, and Airway Effects of Bone‐Borne and Hybrid Expanders in Young Adults

Both bone-borne and hybrid MARPE appliances are effective for correcting transverse maxillary deficiency in young adults. The bone-borne UxL appliance produced greater posterior skeletal expansion, while both systems showed similar effects on airway dimensions. These findings support evidence-based appliance selection in borderline surgical cases, favouring bone-borne devices for enhanced skeletal outcomes.
