目的:分析面部软组织侧貌修复过程中拔牙与非拔牙矫治的影响效应.方法:以正畸矫治,拔牙矫治,软组织侧貌,orthodontics.corrective,tooth extraction,soft tissue profile为检索关键词,应用计算机检索近10年中国期刊网全文数据库、万方数据库、中文科技期刊全文数据库、CBM文章库、Medline(ovid)、Sciencedirect以及手工检索并辅以文章追溯的方法收集国内、国外学者10年内公开发表的有关拔牙与非拔牙矫治软组织侧貌比较的文献.运用meta分析技术对拔牙与非拔牙矫治前后上下唇与审美平面及软组织平面的距离进行综合定量分析,根据资料异质性检验,采用固定效应模型及随机效应模型,计算合并加权均数差及其95%Cl.使用Revman 5.0进行数据处理.结果:共纳入文献5篇,共纳入患者356例.资料异质性检验显示,下唇与审美平面及软组织平面距离变化的异质性检验Ⅰ~2<50%,没有异质性,采用固定效应模型.上唇与审美平面及软组织平面距离>50%,具有异质性,采用随机效应模型.Meta分析结果显示,除上唇与审美平面距离外,上唇与软组织平面、下唇与审美平面及软组织平面距离合并加权均数差及95%Cl均具有显著性意义.结论:拔牙矫治明显减小了下唇与审美平面、软组织平面的距离以及上唇与软组织平面的距离.

OBJECTIVE: To analyze the impact of extraction and nonextraction in soft tissue profile repair. METHODS: Databases of CNKI, Wanfang, VIP Chinese Periodical Database, CBM, Medline (ovid) and Science direct had been searched for studies of soft tissue profile after orthodontic treatment with and without extractions published in recent decade, with orthodontics, corrective, tooth extraction, soft tissue profile as key words. Hand searching was also done to obtain any further information about the studies. Meta analysis was used to comprehensively quantitatively analyze the upper (lower) lip with esthetic plane and soft tissue plane before and after extraction and nonextraction treatment. According to homogeneity test, fixed effect model and random effect model were adopted to calculate weighted mean difference (WMD) and 95% confidence interval (95% Cl).Revman 5.0 was used for data management. RESULTS: Five studies with 356 patients were included. Homogeneity test showed that lower lip-esthetic line and lower lip-soft tissue line Ⅰ~2 < 50%, without heterogeneity, so fixed effect model was adopted. Upper lip-esthetic line and upper lip-soft tissue line were more than 50%, indicating heterogeneity, so random effect model was adopted. Result of meta-analysis showed that, the WMD value and 95% Cl of lower lip-esthetic line, lower lip-soft tissue line, and upper lip-soft tissue line has statistically significance. CONCLUSION: The extraction treatment significantly decreased the distance of lower lip-esthetic line, lower lip-soft tissue line, and upper lip-soft tissue line.
