目的:评价对比自锁托槽与传统托槽矫治错畸形的疗效。方法:计算机检索PubMed(1966~2009.12),Embase(1974~2009.12),Cochrane Library(2009年第4期),CBM(1978~2009.12),CNKI(1994~2009.12),VIP(1989~2009.12)等数据库,筛选比较自锁托槽与传统托槽矫治错畸形的随机对照试验。对纳入的研究进行资料提取与质量评价,运用Rev Man5软件进行Meta分析。结果:最终纳入4个研究,共284例,Meta分析结果提示,拔牙组自锁托槽与传统托槽排齐牙列时间差异无统计学意义[MD=10.00,95%CI(-27.67,47.67),P=0.60];非拔牙组自锁托槽与传统托槽排齐牙列时间差异有统计学意义[MD=-23.48,95%CI(-44.74,-2.22),P=0.03]。磨牙间距的改变拔牙组自锁托槽与传统托槽差异无统计学意义[MD=0.72,95%CI(-0.42,1.86),P=0.22];非拔牙组自锁托槽与传统托槽差异有统计学意义[MD=-1.08,95%CI(-1.77,-0.38),P=0.003]。而尖牙、前磨牙间距改变及切牙唇倾度改变在自锁托槽与传统托槽2组中差异亦无统计学意义。结论:对于拔牙或非拔牙矫治病例,自锁托槽与传统托槽在尖牙、前磨牙间距及切牙倾斜度改变方面并无明显差异;而对于非拔牙矫治方案,自锁托槽可以缩短矫治疗程,更好的改善磨牙间距。
Objective: To evaluate the effect of self-ligating brackets and traditional brackets in correcting malocclusion. METHODS: The databases of PubMed (1966 ~ 2009.12), Embase (1974 ~ 2009.12), Cochrane Library (2009), CBM (1978 ~ 2009.12), CNKI (1994 ~ 2009.12) and VIP , Screening and comparing the self-ligating brackets and traditional brackets correction of malformation deformity randomized controlled trials. Data extraction and quality assessment were included in the included studies and Meta-analysis was performed using RevMan5 software. RESULTS: Four studies were enrolled in 284 patients. Meta-analysis indicated that there was no significant difference in dentition dentition between self-ligating brackets and traditional brackets [MD = 10.00, 95% CI (-27.67, 47.67 ), P = 0.60]. There was significant difference in the time between self-ligating brackets and traditional brackets in dentition group [MD = -23.48,95% CI (-44.74, -2.22), P = 0.03]. There was no significant difference between the self-ligating bracket and the traditional bracket in the tooth extraction group [MD = 0.72,95% CI (-0.42,1.86, P = 0.22] The difference was statistically significant [MD = -1.08, 95% CI (-1.77, -0.38), P = 0.003]. The fangs, premolar pitch changes and incisors lip inclination changes in the self-ligating brackets and traditional brackets 2 group differences were not statistically significant. CONCLUSIONS: There is no significant difference between the self-ligating brackets and the traditional brackets in terms of canine fangs, premolar spacing and incisors’ inclination for cases of tooth extraction or non-extraction treatment, whereas self-ligating brackets can be shortened for non-extraction treatment programs Orthodontic treatment, better to improve molar spacing.
