目的：通过临床验证自锁矫治体系的作用效果，为临床高效、合理地选择矫治体系提供参考。方法：临床选取不需拔牙的安氏Ⅱ类2分类错牙合畸形患者20例，随机分为两组，每组10例。实验组接受自锁矫治系统，对照组接受直丝弓矫治系统，均戴入上颌平面导板打开咬合。矫治前后分别拍摄 X线头颅定位片，制取记存石膏模型。选取X线硬组织和石膏模型指标分析测量，配对检验，比较两种方法矫治前后牙颌组织的变化有无统计学差异。结果：两种方法矫治前后上、下牙弓宽度和牙弓长度均增加，但两组间差异无统计学意义（＞0.05）；两种方法基骨弓宽度均略有增加，两组间的差异有显著性（＜0.05）；两种方法上颌基骨弓长度治疗前后未见明显增加，下颌基骨弓长度治疗前后均有明显增加，上下前牙唇倾度均有明显改善，但两组间，无明显差异。治疗完成时间实验组比对照组缩短，两组间有显著性差异。结论：自锁系统能够扩展牙弓和基骨弓宽度，唇倾前牙，有利于三维方向解除闭锁，在扩展基骨弓宽度上，略优于直丝弓，配合平面导板，可防止托槽脱落、快速打开咬合，缩短治疗时间，特别适合用于安氏II类2分类错牙合畸形的矫治。
目的：通過臨床驗證自鎖矯治體繫的作用效果，為臨床高效、閤理地選擇矯治體繫提供參攷。方法：臨床選取不需拔牙的安氏Ⅱ類2分類錯牙閤畸形患者20例，隨機分為兩組，每組10例。實驗組接受自鎖矯治繫統，對照組接受直絲弓矯治繫統，均戴入上頜平麵導闆打開咬閤。矯治前後分彆拍攝 X線頭顱定位片，製取記存石膏模型。選取X線硬組織和石膏模型指標分析測量，配對檢驗，比較兩種方法矯治前後牙頜組織的變化有無統計學差異。結果：兩種方法矯治前後上、下牙弓寬度和牙弓長度均增加，但兩組間差異無統計學意義（＞0.05）；兩種方法基骨弓寬度均略有增加，兩組間的差異有顯著性（＜0.05）；兩種方法上頜基骨弓長度治療前後未見明顯增加，下頜基骨弓長度治療前後均有明顯增加，上下前牙脣傾度均有明顯改善，但兩組間，無明顯差異。治療完成時間實驗組比對照組縮短，兩組間有顯著性差異。結論：自鎖繫統能夠擴展牙弓和基骨弓寬度，脣傾前牙，有利于三維方嚮解除閉鎖，在擴展基骨弓寬度上，略優于直絲弓，配閤平麵導闆，可防止託槽脫落、快速打開咬閤，縮短治療時間，特彆適閤用于安氏II類2分類錯牙閤畸形的矯治。

Objective To evaluate the clinical effects of the self- ligating bracket system. As a clinical reference for choosing bracket system efficiently and reasonablely. Methods Twelve patients diagnosed as class II division 2 were selected in the study.They all received non- extraction treatment.The patients were assigned to 2 groups:group 1 received non- extraction treatment with a self- ligating bracket and the other group with a conventional bracket.They were combined with occlusal guide to open bit.Lateral cephalometric radiographs and dental casts obtained at the beginning and the end of treatment were used to assess the alteration in hard tissue,and measurements of width and arch length of dentition were made on dental casts to investigate changes associated with the correction.Paired t- tests and group t- tests were used instatistical analysis. Results There was significant increase in length and widths of dental arch with self- ligating and conventional bracket after treatment,there was no significant differences between self- ligatiing and conventional group ( P>0.05);both group were enlarged in widths of the Basal Bone arch after treatment,there was significant differences between self- ligatiing and conventional group ( P<0.05);both groups were no enlarged in length of the maxillary Basal Bone arch after treatment, but they were enlarged in the mandibular Basal Bone arch , also there was significant increase in U1- SNoand L1- MPoin both groups,but there were no significant difference between self- ligating and conventional bracket groups;there was significant change in treat time between two groups, self- ligating groups were less. Conclusion Self- ligating bracket system can cause the proclination of the incisors and increase the arch and Basal Bone width to some degree,It is good to unlock from three dimensional Direction.Self- ligating bracket was better than conventional bracket for increase Basal Bone width.It can prevents the bracket off and open bit quickly combined with occlusal guide,and Shortening the treatment time.Particularly suited for angle class II division 2 malocclusion.
