A clinical study of FR II appliance in early treatment of Class Ⅱ malocclusion
摘要
Abstract
Objective To investigate the clinical effect of function regulatorⅡ(FRⅡ)appliances in the treatment of skeletal ClassⅡ1 malocclusion. Methods Totally 26 child patients with skeletal ClassⅡ1 malocclusion were treated with FRⅡappliances. Cephalometric radiographs were taken and analyzed at pre-treatment and post-treatment. Paired T-test was used to determine if there were significant differences by SPSS 13.0. Results After a treatment by FRⅡ,the growth of the mandible was stimulated. Overbite,overjet,ANB(°)and lip protrusion decreased significantly(P<0.05), while SNB(°)and L1-MP(°)increased significantly(P<0.05). Conclusion FRⅡappliances is fit for the early orth-odontic treatment of skeletal ClassⅡ1 malocclusion. A harmonious relationship between upper and lower jaws and a bet-ter profile can be obtained.关键词
