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)
Skeletal Class II pattern with ANB angle exceeding 6° and Wits appraisal of 2 mm or more.
Mandibular deficiency (SNB angle less than 77°).
Growing patients.
No prior orthodontic intervention.
Developmental abnormalities with atypical or irregular patterns of growth and maturation.
Any indications or manifestations, as well as any prior medical records, of Tempro-Mandibular Joint (TMJ) disorders, such as the presence of clicking, pain, limitations, or deviations.
