Effects of clear aligner-based expansion screw and nickel-titanium palatal expander on airway dimensions and sleep parameters in unilateral cleft lip and palate patients: a randomized clinical trial.

Both clear aligner-based and nickel-titanium palatal expanders improved airway volume and sleep quality in cleft palate patients with transverse maxillary deficiency, with anterior dental widening showing stronger correlation to airway gains than skeletal expansion alone.
