摘　　要：目的 通过直丝弓矫治器辅助微螺钉种植体对双颌前突患者进行拔牙矫治,对矫治前后的数据进行测量分析,评价对面部软组织侧貌的影响程度.方法 选择30例双颌前突患者,采用直丝弓矫治器辅助微螺钉种植体进行拔牙治疗.对矫治前后的头颅侧位X线片进行测量,分析治疗前后面部软组织的变化.结果 上切牙切端平均远中移动6.5 mm,上唇突点平均内收3.8 mm,下切牙切端平均远中移动5.8 mm,下唇突点平均内收5.6 mm,上唇平均向远中移动3.21 mm,下唇平均向远中移动3.67 mm,鼻唇角由治疗前的平均86.7°变为平均103.7°.上下前牙切端移动距离、上下唇突距、鼻唇角的变化差异有统计学意义.结论 直丝弓矫治器辅助微螺钉种植体对双颌前突患者进行拔牙矫治,有效地内收上下前牙,从而有效地改善面部软组织侧貌.Objective To examine the effects of fixed appliance and micro-implant on the improvement of facial profile in patients with protruding.Methods 30 protruding cases were treated by fixed appliance and micro-implant.Cephalometric data before and after treatment were measured and analyzed to assess the effects.Results The upper incisors were retracted 6.5 mm.The upper lip was retracted 3.8 mm.The lower incisors were retracted 5.8 mm.The lower lip was retracted 5.6 mm.UL-E was retracted 3.21 mm.LL-E was retracted 3.67 mm.NLA was changed from 86.7°to 103.7°.The U1-SN,U1-Y,L1-MP,L1-Y,UL-Y,LL-Y,UL-E,LL-E,and NLA demonstrated significant differences between pre-and post-treatment.Conclusions Fixed appliance and micro-implant might retract the anterior teeth and lead to an improvement of facial profile.
