It is a prospective descriptive study to evaluate TMJ disc-condyle-fossa relationship using MRI scan following functional appliance therapy in skeletal Class II Division 2 malocclusion in adolescent females. All records, including MRI scans will be collected at three stages and will be traced for various angular and linear measurements to document the alterations within the condyle glenoid fossa complex 1. Stage- I (pre-treatment), 2. Stage- II (after pre-functional therapy) 3. Stage-III (After 6-8 months of functional appliance therapy that is after correction to Class I molar relation
