This study aimed to compare cephalometric changes of Class II malocclusion patients treated with Jasper Jumper and Forsus, associated with fixed appliances. The sample consisted of 62 individuals divided into 3 groups: group 1 included 22 subjects with a mean initial age of 12.39years, treated with Jasper Jumper associated with fixed appliances for a mean period of 2.43years; group 2 included 19 subjects with a mean initial age of 12.43years, treated with Forsus associated with fixed appliances for a mean period of 3.54years; and group 3 included 22 Class II malocclusion untreated subjects at a mean age of 12.14years, followed for a mean period of 1.78years. Intergroup comparison was performed with one-way ANOVA, followed by Tukey test. 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. The Jasper Jumper and Forsus appliances were effective and showed similar changes in the treatment of Class II malocclusion.
