Introduction: Functional appliances are used to stimulate mandibular growth by forward posturing of the mandible to correct class II skeletal and occlusal disharmony.

Aims and objectives: To evaluate the skeletal, dental and soft tissue effects of Power Scope and Leone Class II Corrector for correction of class II malocclusion.

Materials and Methods: Twenty four subjects were divided on the basis of fixed functional appliance therapy given for correction of class II malocclusion into two groups: Group I treated with Power Scope (n=12) and Group II treated with Leone Class II Corrector (n=12). Lateral cephalogram was taken for all the subjects and various skeletal, dentoalveolar and soft tissue; linear and angular measurements were done and data obtained statistically analysed using independent t-tests.

Results: Statistically significant differences (p>0.05) were found on intergroup comparison of pre-treatment and posttreatment values in both the groups treated for class II correctors. Both the fixed functional appliances were effective in the correction of skeletal Class II malocclusion with statistical insignificant changes were seen in the mean differences (p<0.05) in skeletal, dento alveolar as well as soft tissue.

Conclusion: Both PowerScope and Leone’s Class II Corrector are effective in correcting Class II malocclusion.
