摘要/Abstract

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。

Abstract: Abstract Objective：To investigate the clinical effect of micro-screws with rocking-chair archwire in treatment of Bi-maxillary dental protrusion. Methods: A total of 12 cases of Bi-maxillary dental protrusion patients with removal of four first premolars were chosen。The cases were treated with micro-screws and rocking-chair archwire .Cephalometric indicators changes before and after treatment were compared. Results: 12 patients were successful treated, Incisors retracted significantly :U1-SN mean reduced 12.92°,U1-NA mean reduced 12.92°,U1-NA (mm) mean reduced 5.90mm, L1-MP mean reducted12.75°,L1-NB mean reducted of 9.98°,L1-NB (mm) mean reduction 5.19mm ;Soft tissue profile improved significantly:NLA mean reduced 11.39°,EP-UL mean reduced 3.58mm, EP-LL mean reduced 3.78mm; MPA、OP-FH increased not significantly. Conclusion: Micro-implant anchorage with rocking-chair archwire can effectively treat Bi-maxillary dental protrusion.

Key words: micro-screws, rocking-chair archwire, Bi-maxillary dental protrusion
