Brief summary

This research aims to provide pediatric patients with polysomnography (a sleep study) before and after orthodontic treatment to determine if the extraction of upper premolars for treating excessive overjet results in an increase of the AHI (Apnea Hypopnea Index) compared to similar patients treated without upper premolar extractions.
