摘　　要：目的探讨种植支抗配合摇椅弓矫治双颌前突畸形的临床效果。方法本研究共12例双颌前突患者,均拔除4个第一前磨牙直丝弓固定矫治,应用摇椅弓配合种植支抗矫治内收上下颌切牙完成矫治。矫治前后头影测量分析对比。结果12例患者获得成功矫治,上下切牙明显内收:上中切牙唇倾度U1-SN平均减少12.92°,上中切牙与NA角度U1-NA平均减少13.08°,距离U1-NA(mm)平均减少5.62 mm,下中切牙唇倾度L1-MP平均减少12.75°,下中切牙与NB角度L1-NB角度平均减少12.82°,距离L1-NB(mm)平均减少5.19 mm,变化均具有统计学意义(P<0.01);软组织侧貌明显改善:鼻唇角NLA平均增加9.24°,EP-UL平均减少2.82 mm,EP-LL平均减少2.62 mm,变化均具有统计学意义(P<0.01);MPA,OP-FH没有明显变化(P>0.05)。结论微种植支抗配合摇椅弓可以有效矫治双颌前突畸形。Objective To investigate the clinical effects of implant anchorages with rocking-chair archwire in the treatment of bimaxillary protrusion. Methods 12 cases of bimaxillary dental protrusion patients were chosen. Four first premolars of all cases were removed,and they were treated with implant anchorages and rocking-chair archwire in order to adduct maxillary and mandibular incisors. Cephalometric indicators changes before and after the treatment were compared. Results 12 patients were successful treated with their incisors retracted significantly（ P〈0. 01） ： the mean reduction of U1-SN,U1-NA,U1-NA（ mm）,L1-MP,L1-NB,and L1-NB（ mm） was 12. 92°,13. 08°,5. 62 mm,12. 75°,12. 82°,and 5. 19 mm,respectively. Soft tissue profile improved significantly（ P〈0. 01） ： NLA averagely increased 9. 24°,EP-UL averagely reduced 2. 82 mm,EP-LL averagely reduced 2. 62 mm. MPA and OP-FH didn＇t change significantly（ P〉0. 05）. Conclusions Micro-implant anchorage with rocking-chair archwire can effectively treat bimaxillary protrusion.
