OBJECTIVE To analyze the effects of the Jasper Jumper appliance during the treatment of skeletal Class II malocclusion. METHODS Lateral cephalograms and hand-wrist radiographs were collected from 45 Class II growing patients (22 boys, 23 girls). Three sets of records (initial, before Jasper Jumper, after Jasper Jumper) from 25 patients were compared with 20 control subjects of similar skeletal developmental stage. Mean age of the treatment and control groups were 11.83 years and 11.3 years, respectively. The data were analyzed by using paired t-tests. RESULTS The results demonstrated that the Jasper Jumper effectively corrected Class II malocclusion, but the changes were 80% dentoalveolar. The Jasper Jumper induced a clockwise rotation of the occlusal plane without much alteration in vertical dimension. Skeletally, the maxillary growth was restricted and pogonion moved forward, improving the profile. CONCLUSIONS The Jasper Jumper appliance may be an effective method to improve both the skeletal imbalance and the profile in growing patients.
