自锁托槽非拔牙矫治牙列拥挤的效果观察

Observation on the Effect of Self-locking Brackets and Non-tooth Extraction Orthodontic Crowding

目的探讨自锁托槽非拔牙矫治牙列拥挤的临床效果。方法随机抽样法选取2017年1月-2018年1月南方医科大学顺德医院(佛山市顺德区第一人民医院)90例牙列拥挤患者,平行对照法分为A组(自锁托槽非拔牙矫治)与B组(传统结扎式托槽非拔牙矫治)。比较治疗效果。结果治疗后,A组上下颌第一前磨牙、第二前磨牙、第一磨牙牙弓宽度均大于B组(P<0.05);治疗后,A组UI-NA、UI-NA距低于B组,U1-L1高于B组(P<0.05);治疗后,A组ULP低于B组,Ls-E、Li-E、Snls-SiLi高于B组(P<0.05)。结论牙列拥挤采用自锁托槽非拔牙矫治可改善牙弓宽度及软硬组织,值得临床推广。

Objective To investigate the clinical effect of self-locking socket non-tooth extraction in the treatment of dental crowding.Methods 90 patients with dental crowding in the hospital from January,2017 to January,2018 were selected by random sampling method,and they were divided into group A(non-tooth extraction orthodontic treatment of self-locking brackets)and group B(non-tooth extraction orthodontic treatment of traditional ligation brackets)by parallel control method.The therapeutic effects were compared.Results After treatment,the width of the first premolar,the second premolar,and the first molar arch of the upper and lower jaw in group A were greater than that in group B(P<0.05).After treatment,the distance between UI-NA and UI-NA in group A was lower than that in group B,and U1-L1 was higher than that in group B(P<0.05).After treatment,ULP in group A was lower than that in group B,and Ls-E,Li-E and Snls-SiLi in group A were higher than that in group B(P<0.05).Conclusion Non-tooth extraction orthodontic treatment with self-locking brackets can improve the width of dental arch,and soft and hard tissues,which is worthy of clinical promotion.
