无托槽隐形矫治器与固定矫治器对牙周状况影响的meta分析

目的:通过meta分析评价无托槽隐形矫治器与固定矫治器相比对牙周状况的影响。方法:计算机检索PubMed、EMBASE、The Cochrane Library、CNKI、CBM、Wanfang Data数据库,查找从建库至2017年10月16日国内外公开发表的有关无托槽隐形矫治器与固定矫治器对牙周状况影响的文献。2名研究者独立按照纳入和排除标准筛选文献、提取资料。应用RevMan 5.3软件对提取的数据进行meta分析。结果:共纳入11篇文献,543例患者。Meta分析结果显示,除3个月的牙龈指数与6个月的探诊深度的牙周指数无显著差异外,配戴2种矫治器患者的其余牙周指数具有显著差异(P<0.05),即无托槽隐形矫治器组的牙周指数显著低于固定矫治器组。结论:在正畸治疗矫治初期,无托槽隐形矫治器较固定矫治器更有利于牙周组织健康。

Influence of removable thermoplastic appliances and fixed appliances on periodontal status: a meta analysis

PURPOSE: To evaluate the influence of removable thermoplastic appliances and fixed appliances on periodontal status. METHODS: Cochrane library, PubMed, EMBASE, CBM, CNKI, VIP, Wanfang Database were searched from the date of inception to 2017.10.16,to find clinical trials about removable thermoplastic appliances and fixed appliances on periodontal status. The quality of the included studies was assessed by two reviewers independently, and meta analysis was performed using RevMan5.3. RESULTS: Totally 11 studies including 543 patients were identified. The results of meta analysis showed there were significant difference in PLI and SPD at 3 months and PLI and GI at 6 months between removable thermoplastic appliances and fixed appliances, and no significant difference was observed in GI at 3 months and SPD at 6 months between the two groups. CONCLUSIONS: In the early orthodontic treatment, removable thermoplastic appliances has better effect than the fixed appliance on periodontal health .
