What this Trial Is About

The goal of this clinical trial is to see if expanding the upper jaw with orthodontic therapy can help improve sleep related breathing problems in children. Parents or caregivers will complete the Pediatric Sleep Questionnaire (PSQ) to assess their child's sleep before and after treatment. The study will include 20 children with a narrow upper jaw, and a control group of children without this condition. The main questions it aims to answer are: * Will the 3D scans show significant changes in the face after therapy? * Will the dental scans show a larger palate volume after treatment? * Will parents/caregivers notice an improvement in their children's sleep problems after therapy? Researchers will compare 3D facial and dental scans, as well as PSQ results, before and one year after therapy to see if the treatment makes a difference. Participants will: * Receive orthodontic treatment to expand the upper jaw. * Have their sleep related breathing problems assessed by parents or caregivers using the PSQ before and after treatment. * Have 3D scans of their face and teeth taken before and after treatment.
