Abstract

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. Inter-group differences were evaluated with Wilcoxon signed rank test, and intra-group differences were assessed with Mann-Whitney test at the P < 0.05 level. RESULTS Both were useful in improving the esthetics. However, more AP skeletal changes were seen with TB appliances as compared with Forsus. Vertical skeletal measurements were increased after functional appliances. These results were more pronounced with Forsus appliance than TB. Increase in incisor mandibular plane angle was seen in both groups, but was found to be more pronounced with Forsus group. Similarly, extrusion of upper and lower molars and lower incisors was also seen in both groups. CONCLUSION In this study we found TB to have more mandibular lengthening effect as compared to Forsus, and thus was found to be more effective in treatment of Class II cases.
