摘　　要：目的探讨术前正畸对骨性Ⅲ类畸形患者颞下颌关节关节盘和髁突位置的影响。方法选择骨性Ⅲ类畸形患者20例,通过影像科医生的诊断判定关节盘移位类型,通过对颞下颌关节磁共振图像进行关节间隙测量判定髁突位置情况,观察术前正畸治疗前后关节盘和髁突的位置变化。结果术前正畸治疗不会导致关节盘的位置变化(P>0.05)。术前正畸前后TMJ关节间隙和关节间隙指数变化的差异没有统计学意义(P>0.05)。结论术前正畸治疗不会导致骨性II类畸形患者关节盘和髁突的位置变化。Objective To investigate the effect of pre-surgical orthodontic treatment on the position of articular disc and condyle of temporomandibular joint in patients with skeletal ClassⅢmalocclusion.Methods T wenty patients with skeletal ClassⅢmalocclusion were selected.The type of disc displacement was determined by the diagnosis of radiologist.The condyle position was determined by measuring the joint space on the magnetic resonance imaging of temporomandibular joint.To observe the changes of disc position and condyle position before and after pre surgical orthodontic treatment.Results Pre-surgical orthodontic treatment did not cause disc position variation(P>0.05).There was no significant difference in joint spaces and joint space index before and after the pre-surgical orthodontic treatment(P>0.05).Conclusions Pre surgical orthodontic treatment does not cause the change of disc position and condyle position in patients with skeletal ClassⅢmalocclusion.
