摘　　要：目的:比较正畸舌侧扣结扎(A)、牙弓夹板(B)、正畸片段直丝弓(C)、麻花丝树脂粘结(D)用于外伤松动前牙固定的临床疗效。方法:采用随机同期对照方法,纳入符合条件的137例连续病例(4~14岁),随机采用(A)正畸舌侧扣和0.25mm金属丝结扎、(B)带钩金属夹板和0.4mm金属丝结扎、(C)直丝弓托槽和圆弓丝、(D)0.2mm结扎丝对折三次形成麻花丝后用树脂粘结进行固定,测量松动牙的愈合情况、牙龈指数、操作时间、材料脱落牙数和舒适指数,所得结果进行统计学分析。结果:A、D组的有效固定患者数显著高于B、C组(P<0.05);A、C组的牙龈指数显著低于B、D组(P<0.05);A、B组的操作时间显著低于C、D组(P<0.05);A、C组的材料脱落牙数显著少于D组(P<0.05);A组的舒适指数显著优于B、C、D组(P<0.05)。结论:正畸舌侧扣结扎固定是一种更高效舒适、易操作的松动前牙固定方法。Objective： To compare the clinical effects of orthodontic button ligation fixation （A）, dental arch splint method （B）, straight wire bow fixed orthodontic fragments （C）, and multistrand stainless wire resin bonding fixa- tion （D） in injuries of loose anterior tooth fixation. Methods： One hundred and thirty--seven eligible subjects aged from 4 to 14 years were randomly treated by （A） Orthodontic button and 0.25mm metal wire, （B） Metal splint with hook and 0.4mm metal wire, （C） Straight--wire bracket and circular arch wire, and （D） The 0.2mm ligature wire was folded three times and resin bonding method. The healing conditions of traumatized teeth, gingival index, operating time, shedding rate, and comfortable index were measured. All data were statistically analyzed. Results： The effectively fixed patients number of group A and D were significantly higher than those of group B and C （P〈0.05）. The gingival index of group A and C were significantly lower than those of group B and D （P〈0.05）. The treatment time of group A and B were significantly lower than those of group C and D （P〈0.05）. The shedding rate of group A and C were significantly lower than those of group D （P〈0.05）. The comfortable index of group A were significantly better than those of group B, C, and D （P〈O. 05）. Conclusion： Orthodontic button ligation fixa- tion is more effective and comfortable for the treatment of traumatized loosen teeth.
