自锁与普通直丝弓矫治体系的矫治效率比较

Comparison of orthodontic treatment efficiency between self-ligating brackets and straight wire appliance

目的探讨自锁与普通直丝弓矫治器的矫治效率。方法选择已完成矫治的自锁托槽治疗组24例和普通直丝弓治疗组41例的病历资料进行回顾性分析,比较自锁与普通直丝弓矫治器的矫治效率。结果在拔牙组,非拔牙组数据中,自锁直丝弓的有效复诊次数均少于普通直丝弓矫治组,两组比较结果差异均有统计学意义(P<0.01)。结论自锁直丝弓矫治的矫治效率要高于普通直丝弓矫治,而且其高效率优势主要集中在拔牙病例组。临床矫治效率高,值得推广。

Objective To discuss the orthodontic treatment efficiency between self-ligating brackets and straight wire appliance. Methods 65 completely treated cases were selected. 24 cases with malocclusion were treated by self-ligating brackets. The other 41 ones were treated by straight wire appliance. And we investigated the efficient difference between self-ligating brackets and straight wire appliance,the data were analyzed statistically. Results Among two sets of data from extraction treatment group and non-ex- traction ones, the visit times with self-ligating brackets were lower than straight wire appliance. There was obvious statistical differ- ence among two groups（P〈0.01）. Conclusion The orthodontic treatment effects of self-ligating brackets were superior to straight wire appliance, especially in extraction cases.
