•2. Normal or horizontal growth pattern,
•3. Increased positive overjet (more than 6 mm)
•4. No or minimum crowding in the dental arches.
•For control group:
•1. Subjects with same age group having skeletal class I malocclusion with class I molar relationship
•2. Less than 6 mm overjet,
•3. Treatment done without the use of bite jumping appliance or functional appliance or expansion device or intermaxillary elastics

•1)Medically compromised patients.
•2)Patients with abnormal growth of maxilla.
•3)Patients with history of trauma to Temporomandibular joint.
•4)Patients with previous history of respiratory problems.
