Popis: Objective This study aimed to compare cephalometric changes of Class II malocclusion patients treated with Jasper Jumper and Forsus, associated with fixed appliances. Methods The sample consisted of 62 individuals divided into 3 groups: group 1 included 22 subjects with a mean initial age of 12.39 years, treated with Jasper Jumper associated with fixed appliances for a mean period of 2.43 years; group 2 included 19 subjects with a mean initial age of 12.43 years, treated with Forsus associated with fixed appliances for a mean period of 3.54 years; and group 3 included 22 Class II malocclusion untreated subjects at a mean age of 12.14 years, followed for a mean period of 1.78 years. Intergroup comparison was performed with one-way ANOVA, followed by Tukey test. Results Both treated groups had similar dentoskeletal changes: restrictive effect on the maxilla; clockwise rotation of the occlusal plane; mild increase in lower anterior facial height; limitation on the vertical development of the maxillary molars; labial tipping and intrusion of the mandibular incisors; extrusion of mandibular molars; improvements of the maxillomandibular relationship, overjet, overbite, molar relationship; and retrusion of the upper lip. The mandibular incisors exhibited greater protrusion in group 1 compared to the other groups. In addition, group 2 presented mild protrusion of the lower lip, and groups 1 and 3 showed mild retrusion. Conclusion The Jasper Jumper and Forsus appliances were effective and showed similar changes in the treatment of Class II malocclusion.
