摘要:
目的：评价分析Forsus矫治器治疗安氏II类错牙合下颌后缩患者对牙颌及颞下颌关节的影响。方法：选取21例下颌后缩的安氏II类错牙合畸形的青少年患者，使用Forsus矫治器引导下颌向前，每位患者治疗前后均进行CBCT扫描，通过Invivo 5软件分别对治疗前后的颌骨、牙与牙槽、颞下颌关节有关数据进行测量，并应用Pancherz分析法对治疗前后的颌骨变化进行对比。结果：经统计学对比发现在治疗前后两组中，与髁状突在关节窝内位置的有关测量指标没有明显差异（P>0.05），与颌骨相对位置有关的Pancherz测量指标有明显差异（P<0.05）。结论：安氏II类错牙合下颌后缩的青少年患者经Forsus矫治器治疗后，颞下颌关节髁状突位置改变较少，下颌骨发生明显的向前生长，侧貌的改善和咬合关系的纠正主要是由牙槽骨的适应性改建和颌骨的生长完成。
Abstract:

Objective: To evaluate the effect of Forsus appliance on maxillofacial and temporal- mandibular joint of class II mandibular retrusion malocclusion.

Methods: Twenty one youth patients with class II mandibular retrusion were treated with Forsus appliance and scaned with CBCT before and after treatment. The tooth, maxillofacial and temporal-mandibular joint were rebuilt and measured by Invivo 5 software, and the changes of maxillary and mandilular were metered by Pancherz analysis. Results: The indexes related to position of condyle were not significant changed (P>0.05), and the Pancherz analysis indicated significant difference between pre- and postreatment(P<0.05). Conclusion: With the treatment of Forsus, the condyle of temporal-mandibular joint could not change obviously, the mandibular grows forward, and the position of occlusion and lateral face is corrected probably due to the growth of mandibular and the rebuild of alveolar.
