简要总结
The goal of this is to evaluate the skeletal, dental and soft tissue effects between aesthetic functional appliance and Twin block appliance in treatment of skeletal class II in ( growing male/female patients)
详细描述
The sample will be randomly divided into 2 equal groups according to the appliance will be used:
Group 1: Aesthetic Functional appliance Group 2: Twin block
Methods:
*Radiographs (CBCT) will be taken before starting the treatment (T1) and after obtaining Class I occlusion and normal overjet (T2) by sequential appliances.
