Abstract

INTRODUCTION Class II malocclusion second most common malocclusion after class I. The prevalence of Class II malocclusion was reported 19.56% globally(2) and 14.6% in India. Management of class II malocclusion becomes intricate because of its variable etiology and the age at which the patient presents to the orthodontists. During 1900 first fixed functional appliances (FFA) emerged and then plethora of appliances followed. Amongst various appliances AdvanSync™ appears to be the latest addition to FFA in orthodontist’s arsenal whereas Forsus™ Fatigue Resistance Device (FFRD) is the most widely accepted and used FFA. AIMS &OBJECTIVES: The aim of this study is to compare the differences in the skeletal, dentoalveolar and soft tissue changes produced by AdvanSync™2 and FFRD METHODOLOGY: The sample comprised of 30 patients presented to the Department of Orthodontics and Dentofacial Orthopaedics, as outpatients. Total 15 patients in each group were treated and analyzed using Lateral cephalograms at two time period, pretreatment and post functional orthodontic treatment. RESULTS: Both the appliances were effective in normalising class II malocclusions with mandibular deficiency. Both the appliances showed more of dentoalveolar effects when compared to skeletal. They both have a positive effect on the profile CONCLUSION: The FFRD and AdvanSync™2 both the appliances were effective in treating class II division malocclusion. AdvanSync™2 demonstrated greater headgear effect but less mandibular advancement as compared to FFRD. Both appliances caused significant dentoalveloar changes and soft tissue changes.
