What this trial studies

This clinical trial aims to compare the effectiveness of a protraction facemask and an upper partial fixed appliance in correcting anterior crossbite in growing children with class III malocclusion. Participants aged 7 to 10 years will be randomly assigned to one of the two treatment groups. The study will assess the success rates of each method, differences in dental and skeletal outcomes, patient perceptions, and any adverse effects associated with the treatments. Comprehensive orthodontic assessments and imaging will be conducted to evaluate the results.
