Study of Functional Appliance Twin Block Effects on Jaw Growth and Sleep Breathing Problems in Children Ages 10 to 14

What this Trial Is About

Researchers are studying children aged 10 to 14 years who have a retrognathic mandible, a condition where the lower jaw is positioned backward. The trial aims to evaluate how functional appliance therapy using the Twin Block device affects 3D craniodentofacial features and reported sleep-related breathing disorders. This research also includes assessing the impact of the therapy on upper airway dimensions and sleep problems, which are important for overall child growth and development. Participants will receive the Twin Block functional appliance proposed after diagnostics, which they will wear for about one year. Three-dimensional facial scans will be taken before treatment, including at rest and with the mandible moved forward using the Fraenkel maneuver, as well as after the treatment ends. Caregivers will complete the Pediatric Sleep Questionnaire PSQ before and after treatment to evaluate perceived changes in sleep-related breathing issues. Additionally, lateral cephalogram X-rays will be taken from enrollment to the end of treatment to support the assessment. During the study, children will undergo detailed facial scans and X-rays to monitor changes in their facial structure and airway. Caregivers will provide input through questionnaires to assess sleep breathing problems. Researchers will compare initial scans and predicted treatment outcomes with actual results to evaluate therapy effectiveness. The total participation period is approximately one year, during which the team will closely observe facial growth, airway changes, and sleep-related symptoms to understand the therapys influence.
