摘要/Abstract

摘要： 目的观察Forsus推杆式矫治器对发育高峰期安氏Ⅱ类1分类下颌后缩患者牙、、颌面结构的影响。方法应用Forsus矫治器对11例生长发育高峰期的Ⅱ类1分类错 患者治疗，利用winceph7.0头影测量软件分析治疗前后头颅侧位片。结果 ANB角减小3.36°，SNB角增加3.05°，下颌体长度增加3.34 mm，Pg到OLP平面的距离增加2.32 mm，覆盖减少，磨牙关系改善，有显著性差异。结论 Forsus推杆式矫治器对发育高峰期下颌后缩患者有较好的下颌骨矫形效果，能促进下颌生长发育，使软硬组织侧貌得到改善。

Abstract: Objective To observe the clinical effects of Forsus appliance in the treatment of Mandibular Retrusion during the peak stage of development. Methods 11 Mandibular Retrusion patients were treated with Forsus appliance. Winceph 7.0 Cephalograms Analysis Software was used to analyze lateral cephalograms before and after the treatment. .Results ANB decreased by 3.36°while SNB increased by 3.05° and the mandibular body length was 3.34mm longer. The distance from Pg to OLP plane increased by 2.32mm with overjet decreased and the molar relationship improved significantly. Conclusion Forsus appliance is effective to correct Mandibular retrusion at the peak stage of development. It can stimulate the mandibular growth and improve sagittal discrepancy and soft tissue profile convexity significantly.
