【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(P0.05);A、C组的牙龈指数显著低于B、D组(P0.05);A、B组的操作时间显著低于C、D组(P0.05);A、C组的材料脱落牙数显著少于D组(P0.05);A组的舒适指数显著优于B、C、D组(P0.05)。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。
[Abstract]:Objective: to compare the clinical effects of orthodontic lingual ligation (An), dental arch splint (BJ), orthodontic segment (C) and hemp silk resin (D) in the treatment of traumatic loosening teeth. Methods: a randomized simultaneous control method was used. One hundred and thirty-seven consecutive cases, aged 14 years old, were enrolled in the study. They were randomly divided into two groups: a) orthodontic tongue side buckle and 0.25mm wire ligation (B) with hook metal splint and 0.4mm wire ligation with straight wire arch bracket and circular arch wire (D0. 2mm ligation wire in twistedfold) to form flax wire in three times. And then fixed with resin, The healing, gingival index, operating time, number of lost teeth and comfort index of loose teeth were measured, and the results were analyzed statistically. Results the number of effective fixation patients in group D was significantly higher than that in group B (P 0.05). The gingival index of group A was significantly lower than that of group B (P 0.05). The operating time of group B was significantly lower than that of group C (P 0.05). The number of teeth lost in group C was significantly lower than that in group D (P 0.05A), and the comfort index of group A was significantly better than that of group B (group B). Conclusion: orthodontic ligation and fixation of lingual side buckle is a more efficient and easy-to-operate method for loosening anterior teeth.
