Objective Study was conducted to 3D evaluate skeletal effects of two different intraoral force application systems for treating skeletally growing ClassIII patients(RCT). Material and Methods 33 patients recruited and randomly allocated between three groups: GroupI(n = 11)treated with CS2000(CSgroup/ pulling force), GroupII(n = 11)treated with reversed Forsus Fatigue Resistant(RFgroup/ pushing force) and GroupIII(n = 11)untreated control(negative control). A CBCT taken before treatment(T0) and after gaining a 2mm overjet or after observation period of 6months(T1). Skeletal measurements were assessed and compared between groups. Within group comparisons were done using Wilcoxon Sign Rank test. Results Sagittaly in RFgroup, OLp-Apt increased by3.60mm, OLp-Bpt decreased by-2.50mm and OLp-Pg decreased as well by-2.00mm(P P P |
