摘　　要：目的系统评价热激活镍钛弓丝在正畸治疗中的矫治效率。方法检索PubMed、Cochrane library、Web ofscience、Embase、中国生物医学文献数据库(CBM)、中国知网(CNKI)、中文科技期刊数据库(VIP)和万方数据库,查找比较热激活镍钛弓丝与其他镍钛弓丝矫治效率的随机对照试验(RCT),检索时间都为建库到2017年11月30日。文献筛选及提取资料均由2位研究者独立完成,然后利用Cochrane的“风险偏倚评估工具”对纳入的研究进行质量评价,最后使用Review Manager(RevMan)5.3.0软件进行Meta分析。结果本研究共纳入8篇研究,456名受试者,并对其中4个研究进行了Meta分析。Meta分析结果显示:热激活镍钛弓丝与对照镍钛弓丝相比,两者在排齐整平时间、托槽脱落次数、总疗程和疼痛视觉模拟评分法(VAS)指数方面的差异均具有统计学意义。定性分析结果与Meta分析结果一致,同时两者在弓丝断裂次数方面也有显著差异,但在排齐效率方面差异无统计学意义。结论热激活镍钛弓丝在排齐整平时间、总疗程、托槽脱落次数、弓丝断裂次数和患者舒适感等方面均优于其他镍钛弓丝。Objective In this study, we aimed to conduct a systematic review of the clinical effectiveness of heat-activated Ni-Ti (HANT) wires in orthodontic treatment.Methods A search was conducted in PubMed, the Cochrane library, Web of science, Embase, China Biology Medicine (CBM), China National Knowledge Infrastructure (CNKI), Chinese Scientific and Technological Journal (VIP) and Wan Fang databases until 30 November 2017.Then, we collected the randomised controlled trials (RCT) about the clinical effectiveness of HANT wires versus other Ni-Ti wires.The extraction of data and risk of bias evaluation were conducted by two investigators independently.Then, RevMan 5.3.0 software was used to conduct the meta-analysis.Results We included 8 trials which recruited 456 participants.Four studies were statistically pooled in meta-analysis.Meta-analysis results showed that patients with HANT wires had significantly lower time of levelling, bracket shedding, total course and visual analogue scale scores than those with other Ni-Ti wires.Qualitative analysis results were consistent with meta-analysis findings.The differences in wire breaking was significant, but no differences were found in alignment efficiency.Conclusion HANT wires were more effective than other Ni-Ti wires in terms of the time of levelling, bracket shedding, total course, wire breaking and comfort in orthodontic treatment.
