Dentoskeletal Comparison of Changes Seen in Class II Cases Treated by Twin Block and Forsus.

Background: To evaluate skeletal and dentoalveolar effects of Forsus fatigue resistant devices (FRD) and twin-block (TB) appliance in Class II malocclusion cases.

Materials And Methods: Twenty young adult patients (age 13-17 years, overjet 6-10 mm) with a Class II division 1 malocclusion were randomly divided into two groups: group I included 10 patients treated with TB, Group II included 10 patients treated with FRD. Dentoskeletal changes were analyzed on lateral cephalograms taken before (T1) and (T2) at the end of the treatment.
