| 目的 探讨自锁托槽在非拔牙正畸治疗中的应用体会。方法 选择错颌畸形患者60例,30例患者采用自锁托槽作为试验组,30例患者采用传统直丝弓矫治器作为对照组,均进行非拔牙矫治。结果 试验组治疗成功率为96.67%,对照组成功率为66.67%,对照组无效的10例患者有可能进行拔牙矫正才能排齐牙列。试验组成功率明显优于对照组,差异有统计学意义(P<0.05)。结论 自锁托槽降低了弓丝与托槽的摩擦力,同时具有扩弓作用,在非拔牙矫治中占有明显优势,值得在临床推广。 |

| Objective To investigate the application of self-ligating brackets in non-extraction orthodontic treatment.Methods Sixty patients with malocclusion were selected. 30 patients treated with self-ligating brackets were recruited as experimental group and 30 patients treated by traditional straight wire appliance as control group. Both groups received non-extraction treatment.Results The effective rate of experimental group was 96.67%, while that of the control group was 66.67%, and invalid 10 patients of control group may receive extraction treatment to align dentition. The success rate of experimental group was significantly higher than that of control group, and the difference was statistically significant(P<0.05).Conclusion Self-ligating bracket reduces the friction between archwire and bracket, and also with arch-expansion effect, which has obvious advantages in non-extraction treatment, thus it is worth clinical promotion. |
