[摘要]目的：研究肌功能训练对安氏Ⅱ1下颌后缩患者的疗效，并对疗效产生的可能机制进行探讨。方法：选取安氏Ⅱ1下颌后缩患者10例，年龄8～10岁，均处于生长发育期。采用肌功能训练治疗，利用头颅侧位片进行治疗前后硬组织的测量分析，选取硬组织测量项目22项。结果：通过肌功能训练前后的头影测量对比分析显示，肌功能训练后，Go-Me距增加、Ar-Go增高、SNB角增大（P

Abstract： Objective  This study researched the effects of myofunctional training therapy to Class Ⅱ1mandibular retrognathia patients，and the effect of the myofunctional training on these cases was discussed in detail. Methods 10 patients who were all Class Ⅱ1mandibular retrognathia during growth were selected. Their age was during 8 to 10. They all accepted myofunctional training therapy. They were photographed cephalometric X-ray pretherapy and post-treatment. Hard tissue was analyzed by cephalometric X-ray. 22 indicators of hard tissue profile were gathered. Results Cephalometric measurement showed that： after myofunctional training the distance of Ar-Go and Go-Me increased. The angle of SNB also increased and the angle of ANB and NA-PA decreased（P
