骨皮质切开术辅助正畸治疗的临床研究

Clinical study of corticotomy assisted orthodontic treatment

目的探讨骨皮质切开术辅助正畸治疗的临床应用。方法研究临床接受骨皮质切开术辅助治疗的正畸患者48例,男14例,女34例。骨皮质切开术应用于正畸临床:辅助扩弓,拔牙患者的前牙内收,修复前正畸治疗的磨牙前移、残冠牵引,根骨粘连牙齿的移动等。结果在正畸治疗中,辅助骨皮质切开术可以解除骨皮质阻力,加速正畸牙齿移动,增加牙周支持组织及骨覆盖,减少牙根吸收。结论骨皮质切开术辅助正畸治疗不仅可以加速牙齿移动,而且能够有效解决正畸临床的一些疑难问题。

Objective To investigate the clinical effect of corticotomy assisted orthodontic treatment. Methods 48 orthodontic patients were selected,14 males and 34 females,and they all accepted corticotomy assisted orthodontic treatment. Corticotomy had been used in the clinical treatment： auxiliary arch expansion,extraction of anterior teeth retraction,molar anterior displacement,traction crown,root bone adhesion teeth mobile,etc. Results Corticotomy could remove the cortical resistance,accelerate the orthodontic tooth movement,increase the periodontal support tissue and bone cover,reduce the root resorption,and enhance the stability of the treatment. Conclusion Corticotomy assisted orthodontic treatment can not only accelerate the tooth movement,but also effectively solve some difficult problems of the orthodontic treatment.
