Introduction - For the successful correction of Class II malocclusion, the use of functional appliances such as FR II, TB, and Forsus FRD can be highly effective initially followed by a fixed appliance treatment later. This study has been done to analyze the impact of FR II, TB, and FRD on a class II malocclusion patient on skeletal, dentoalveolar, and soft tissue. Materials and Methods: The study included 60 patients aged between 12±0.85 and 14±0.91 years, divided into 3 groups of 20 patients. Group A, Group B, and Group C were treated with FR II, TB, and Forsus FRD respectively. All patients had class II malocclusion, cusp-to-cusp molar relationship, minimal or no crowding in mandible, overjet not less than 5mm, no previous orthodontic treatment etc. The patients were followed up regularly and their skeletal, dentoalveolar, and soft tissue changes were recorded, evaluated, and compared to determine which appliance resulted in these changes. Result: FR II shows forward mandibular growth and positive soft profile. TB shows mandibular growth in sagittal and vertical dimensions, correcting the overjet and reducing facial convexity. The group with Forsus FRD shows mandibular growth through continuous, low-force stimulation, aiding in the coordination of dental arches. Conclusion: FR II shows marked changes in the dentoalveolar relationship with a direct impact on soft tissue changes, TB shows significant skeletal and dentoalveolar changes with a positive effect on soft tissues, Forsus FRD group shows both skeletal and dentoalveolar changes but indirect and very minimal soft tissue changes.
