功能矫治器对生长发育期骨性Ⅱ类错[牙合]患者气道影响的Meta分析

目的分析功能矫治器早期干预对骨性Ⅱ类错[牙合]患者的气道影响。方法应用Medline、万方、维普和中国知网数据库检索1965年1月至2019年12月期间发表的有关不同功能矫治器对生长发育期骨性Ⅱ类错[牙合]气道影响的文献,筛选并提取数据进行质量分级,用Revman5.3软件对数据进行Meta分析。结果共纳入骨性Ⅱ类错[牙合]患者326例,其中将功能矫治器早期干预者分为试验组,未行治疗者为对照组。试验组中蝶鞍点-鼻根点-下齿槽座点角(SNB)和口咽体积(Or-V)变化值的增加均高于对照组,差异有统计学意义(P<0.05)。两组舌骨-下颌平面(H-MP)、会厌谷-咽下壁(V-LPW)、悬雍垂-咽中壁(U-PPW)和TB-咽后壁(TPPW)变化值的增加差异无统计学意义(P>0.05)。结论功能矫治器可促进生长发育期骨性Ⅱ类错[牙合]患者下颌骨的位置前移,同时可一定程度的改善通气功能。

Objective To study the effect of early intervention with functional appliances(FAS)on airway dimensions with skeletal class U malocclusion in order to provide clinical evidences for the theory of improving the function of respiratory.Method To searched the studies on changes of airway dimensions following different FAS in growing patients with skeletal class Ⅱmalocclusion using MEDLINE,Wan fang and VIP and China How Net databases,which published between January 1965 and December 2019.Screened and extracted and evaluated its quality.The data was assessed by Meta analysis using Revman5.3 software.Results 326 patients with skeletal Class Ⅱ malocclusion were contained in the test.Treated patients were divided into experimental group intervened by FAS early and untreated were in control group.The increase of SNB and Or-V in experimental group were all higher than that in control group(P<0.05).The changes of MP-H and V-LPW and U-MPW and TB-TPPW had no statistical significance in both groups(P>0.05).Conclusion The FAS can improve the position of mandible in a forward and also improve the function of respiratory to some extent in growing patients with skeletal class Ⅱ malocclusion.
