下颌偏斜患者髁突位置的meta分析

目的:系统评价下颌偏斜患者髁突位置与个别正常▉髁突位置的差异。方法:计算机检索Pubmed、Embase、中国知网、万方数据库、维普、中国生物医学文献数据库,纳入所有关于下颌偏斜患者髁突位置的文章。检索时间截至2017年6月。由2名评价员独立进行资料提取和交叉核对后,采用RevMan5.3软件进行统计学分析。结果:共纳入6篇文献,均为下颌偏斜患者与个别正常▉髁突位置对照的研究。其中,下颌偏斜患者122例,个别正常▉110例。Meta分析结果表明,下颌偏斜组偏斜侧关节上间隙MD=-0.38,95%CI(-0.74,-0.01),P=0.04]、前间隙MD=-0.72,95%CI(-0.99,-0.04),P<0.00001]均显著大于偏斜对侧;下颌偏斜组偏斜侧关节后间隙MD=-0.35,95%CI(0.25,0.45),P<0.00001]显著小于偏斜对侧;与个别正常▉相比,偏斜组偏斜侧关节后间隙MD=-0.58,95%CI(-0.88,-0.28),P=0.0002]偏斜对侧关节后间隙MD=-0.30,95%CI(-0.59,-0.00),P=0.05]及关节前间隙MD=-0.85,95%CI(-1.58,-0.13),P=0.02]均显著小于对照组。偏斜组偏斜侧MD=-0.56,95%CI(-1.14,0.02),P=0.06]及对侧关节上间隙 MD=-0.58,95%CI(-1.27,0.10),P=0.10],偏斜组偏斜侧关节前间隙MD=-0.05,95%CI(-0.35,0.46),P=0.80]与对照组相比,差异均无统计学意义。结论:下颌偏斜患者偏斜侧髁突位置较偏斜对侧向后下移位。与个别正常▉相比,下颌偏斜患者偏斜侧髁突位置向后移位。

Meta-analysis of the condylar position with mandibular deviation

PURPOSE: This study was aimed to analyze the differences of condylar position between the mandibular deviation and the individual normal occlusion. METHODS: Databases of PubMed,Embase ,CNKI ,Wanfang ,VIP and CBL were searched for the relevant articles about condylar position with mandibular deviation. The deadline was June 2017.Data quality evaluation and extraction were independently conducted by two authors. Then meta analysis was performed using Rev Man 5.3 software. RESULTS: Six articles on controlled study of the condylar position in patients with mandibular deviation and individuals with normal occlusion were included. 122 patients had mandibular deviation and 110 had normal occlusion. Meta analysis results showed that the condylar superior spaceMD=-0.38,95%CI(-0.74,-0.01),P=0.04]and anterior spaceMD=-0.72,95%CI(-0.99,-0.04),P<0.00001]of the deviation side in mandibular deviation group were significantly greater than that of the opposite side; The condylar posterior spaceMD=-0.35,95%CI(0.25,0.45),P<0.00001]of the deviation side in mandibular deviation group was significantly smaller than that of the opposite side. The condylar posterior space of deviation sideMD=-0.58,95%CI(-0.88,-0.28),P=0.0002],opposite sideMD=-0.30,95%CI(-0.59,-0.00),P=0.05] and the anterior space of opposite sideMD=-0.85,95%CI(-1.58,-0.13),P=0.02] in the mandibular deviation group was significantly smaller than that in the individuals with normal occlusion; the differences were statistically significant. There was no significant difference in the condylar superior space between the deviation sideMD=-0.56,95%CI(-1.14,0.02),P=0.06] and the opposite sideMD=-0.58,95%CI(-1.27,0.10),P=0.10] and the anterior spaceMD=-0.05,95%CI(-0.35,0.46),P=0.80]in deviation side in the mandibular deviation group ,comparing with individuals with normal occlusion. CONCLUSIONS: The condylar position of deviation side in patients with mandibular deviation is posterior and inferior, comparing with the opposite side. The condylar position of deviation side in patients with mandibular deviation is posterior, comparing with the individuals with normal occlusion.
