About

The goal of this clinical trial is to compare the pharyngeal airway changes after treatment with Myobrace and after treatment with Twinblock in developing skeletal Class II patients.

The main question it aims to answer is: Is the efficacy of the twin-block Vs Myobrace appliances in the improvement of pharyngeal airway dimensions in adolescents having skeletal Class II malocclusion with retrognathic mandible utilizing sagittal pharyngeal airway area measurements.
