目的探讨如何针对个体反牙合机制进行早期阻断治疗，诱导建立正常牙合。方法采用功能及各种加力矫治器并口外力综合运用治疗少儿反牙合，比较各年龄段对不同矫治方法的反应，评价其结果。结果全部病例反牙合解除，面部矢状方向得到不同程度发育，替牙牙合以ＦＲ３作用最为显著。结论反牙合的疗法取决于患儿所处的年龄阶段及牙合颌面形态特征，既往矫治方法单一是造成失败的主要原因
Objective To explore how to treat early occlusion of individual anti-occlusal mechanism and induce normal occlusion. Methods The function and all kinds of force appliance were used to treat children 's anti - occlusion combined with external force. The response of different age groups to different methods of correction was compared and the results were evaluated. Results In all cases, anti-occlusion was relieved, and facial sagittal direction was developed to varying degrees. The most obvious effect of molar occlusion was FR3. Conclusion Anti-occlusal therapy depends on the age of the patient and the morphological features of the occlusal and maxillofacial region. The previous single correction method is the main reason for the failure
