MARPE effects on sleep and the upper airway.

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This interventional protocol enrolls 15–18-year-old patients with maxillary transverse deficiency who receive miniscrew-assisted rapid palatal expansion (MARPE) as part of routine care. Participants complete the teen-STOP-BANG and Pittsburgh Sleep Quality Index (PSQI) at treatment start (T1) and after a 3-month consolidation period (T2), while CBCT scans at both timepoints measure changes in oropharyngeal and nasopharyngeal airway dimensions. Midpalatal suture maturation on the initial CBCT guides selection of MARPE versus conventional RME, and a follow-up CBCT at the end of screw activation checks for complications such as zygomatic buttress fractures, alveolar bending, dehiscence, or fenestration. The protocol compares pre- and post-treatment airway metrics and sleep-related questionnaire scores to determine whether MARPE leads to measurable airway widening and improved sleep-related risk indicators.
