自锁托槽和结扎式托槽矫治排齐时间比较研究

Comparative study on alignment time of Smart clip self-ligating appliance and traditional ligation bracket appliance

目的:评价正畸治疗采用Smartclip自锁托槽矫治器的优越性。方法:随机抽取临床病例72例,其中使用Smartclip自锁托槽的36例(A组)、传统MBT金属托槽36例(B组),所有病例均为恒牙期错牙合畸形,中度拥挤。分别记录基本排齐所需要的时间,并进行统计学分析。结果:A组排齐时间为3.6个月,B组的排齐时间为5.9个月,差异有统计学意义(P<0.01)。结论:Smartclip自锁托槽矫治器能明显缩短牙齿排齐时间,从而缩短疗程。
