目的：对正畸正颌联合矫治骨性Ⅲ类错(牙合)畸形在术后3年前牙位置及硬组织的稳定性进行系统评价。方法采用计算机检索及手工检索相结合的方式，全面查找研究正畸正颌联合矫治严重骨性Ⅲ类错畸形的所有文献，检索日期截止2013年12月。严格按照纳入标准和排除标准筛选文献，对纳入研究的文献进行质量评价，采用Rev?Man5.2软件对前牙位置及硬组织相关指标稳定性进行Meta分析或描述性分析。结果研究最终纳入4篇文献，均为前后对照试验，共180例患者，文献评价等级均为A。Meta分析结果表明：术后3年与术后相比，U1-SN的合并加权均数差?（WMD）为4.29，差异有统计学意义（P<0.05）；L1-MP、OB、OJ、SNA、SNB、ANB、MP-SN的合并WMD分别为-1.58、0、-0.41、-0.58、0.25、-0.70、0.39，差异均无统计学意义（P>0.05）。描述性分析表明，术后3年A点位置相对稳定，B点较术后有轻微复发（P<0.05）。结论下前牙的位置及前牙覆覆盖较为稳定，上前牙有轻微复发唇倾；上颌骨的位置基本保持稳定，仅下颌骨有少量的向前复发。
