Aim: The aim of this study was to evaluate and compare the skeletal and dentoalveolar effects of Jasper Jumper (JJ) and activator-headgear (AcHg) combinations and an untreated control group. Materials and Methods: The sample comprised 37 Class II high-angle patients. Twenty of them (mean age: 12.4 ± 0.61 years) were treated with JJ and 17 of them (mean age: 10.9 ± 0.74 years) were treated with AcHg. Mean treatment time was 5 months for the JJ group and 11 months for the AcHg group. Control group consisted of 20 Class II high angle patients (mean age: 10.4 ± 0.41 years) and mean observation period was 10 months. Results: Co-A showed significant increase in the JJ and control groups while SNA angle decreased significantly in only JJ group. Increase in SNB angle in AcHg group was significantly greater than in the JJ and control groups. In the JJ group, mandibular incisors protruded significantly. Conclusion: Both the AcHg and JJ treatments had restraining effect on maxillary growth, but stimulated significant mandibular growth. Anteroposterior discrepancy was corrected in the AcHg group mostly by the mandibular growth compared to JJ treatment. Maxillary incisors were retroclined in the AcHg group while mandibular incisors were proclined in the JJ group. |
