改良Forsus矫治器与肌激动器治疗安氏Ⅱ类下颌后缩疗效对比研究
The analysis of the treatment to Class Ⅲ patients between with modified forsus appliance and with Activator appliance by pancherz
摘要
Abstract
Objective: To evaluate and analysize the effects between with modified Forsus appliance and activator in the treatment of Class Ⅱ madibular retrusion by Pancherz. Method: 40 children with Class Ⅱ malocclusion and mandibular retrusion were selected and divided into two groups.20 patients treated with this new appliance and other 20 treated with activator. Cephalometric radiographs were taken and analyzed at the pre-treatment time(Tl) and the post-treatment time (T2) with the Pancherz analysis. Students' t-test was used to determine if there were significant differences between the 2 time periods. Result: After treatment, profiles of the two groups were obviously improved. The trends were similar in overjet and the molar relationship, SNB and ANB.all had significant differences. Conclusion: Both the modified Forsus appliance and activator appliance combined with straight wire appliance can effectively stimulate the mandibular growth, balance the jaw relationship, and correct the Class Ⅱ mandibular retrusion.关键词
