ABSTRACT:Fixed functional appliances have been used for correction of skeletal class II malocclusion for sometime now, with the Forsus being a relatively newer addition. 6 skeletal class II patients were treated with Forsus spring for an average period of 6 months, after decompensation with 1st premolar extraction. The main objective was to evaluate the Skeletal, Dental and Soft tissue profile changes resulting in the correction of the class II malocclusion to either Class I or Super Class I occlusal relationship. Lateral cephalograms were taken before (T1) and after (T2) the fixed functional phase. Results showed significant improvement in soft tissue convexity and both skeletal and dental parameters contributed to the correction of overjet and molar relation. The skeletal contribution for overjet correction was 31.62% whereas the dental was 68.37%. The molar relation was corrected skeletally by 41.91% and dentally by 58.08%. The occlusal plane was rotated by 6.50 in a clockwise direction. This study concluded that dental changes contributed more to the correction of the malocclusion.
