研究概览
简要总结
This study aims to compare the skeletal and dentoalveolar changes produced by two maxillary expansion appliances namely MARPE and Hybrid Hyrax in patients with transverse maxillary constriction. The study includes eighteen participants aged between twelve and seventeen years who are undergoing fixed orthodontic treatment. Participants are divided into two groups based on the type of expander used. Three dimensional CBCT images are taken before maxillary expansion and three months after completion of expansion following the retention period. Skeletal alveolar and dental changes in the maxilla and mandible are evaluated in coronal and axial planes using CBCT measurements. The results of this study will help in understanding the pattern and magnitude of changes produced by MARPE and Hybrid Hyrax appliances and assist in selecting the appropriate expansion method in adolescent patients.
