Comparing Two Orthodontic Expanders for Better Breathing and Jaw Growth in Children

Sleep Apnea | Children | Orthodontics

This study aims to compare two orthodontic expanders—Invisalign Palatal Expander (IPE) and Hyrax Expander (RPE)—to see which is more effective in improving nasal breathing, sleep quality, and jaw growth in children with a narrow upper jaw (maxillary transverse deficiency). The study will measure airflow, sleep patterns, and jaw changes over a year. By understanding how these devices affect breathing and jaw development, this research will help orthodontists choose the best treatment for children who need palatal expansion.
