Sponsor's own description
This study is intended primarily to compare the effects of two Class II correction appliances, namely Twin block and Myobrace appliances, on pharyngeal airway dimensions during the treatment of class II division 1 adolescent patients, also evaluates three dimensional (3D) changes of pharyngeal airway including: minimum cross-sectional area and volume using Cone Beam Computed Tomography (CBCT), skeletal, dentoalveolar, and soft tissue changes using cephalometric analysis, and three dimensional (3D) soft tissue changes using facial scans. The hypothesis being a consideration of no significant difference in the changes of pharyngeal airway and facial dimensions in skeletal class II patients before and after treatment with Twin block and Myobrace.
