【摘要】：目的:比较牙支持式及混合支持式扩弓器进行上颌快速扩弓的临床效果。方法:计算机检索PubMed、Cochrane Library、EMbase、CBM、中国知网、维普、万方数据库,收集所有比较牙支持式及混合支持式扩弓器进行上颌快速扩弓的文献,检索时限均从建库至2015-10-31。按照纳入、排除标准,由2位研究者评价纳入研究的质量并提取资料后,采用Rev Man 5.3软件进行Meta分析。结果:共纳入研究8篇,患者206例。Meta分析结果显示,牙支持式及混合支持式扩弓器相比,两者在扩弓矫治前后右侧第一磨牙倾斜角度变化[MD=-1.62,95%CI(-3.18,-0.07)]、第一前磨牙间距变化[SMD=-0.86,95%CI(-1.47,0.25)]、牙槽突倾斜角变化[SMD=-0.86,95%CI(-1.10,-0.20)]方面的差异有统计学意义。在扩弓矫治前后第一磨牙间距变化[SMD=-0.08,95%CI(-0.61,0.45)]、左侧第一磨牙倾斜角度变化[MD=-1.12,95%CI(-2.57,0.33)]、上颌骨横向宽度变化[SMD=-0.30,95%CI(-1.08,0.47)]方面的差异无统计学意义。结论:牙支持式及混合支持式扩弓器对上颌牙弓的扩张效果相当,牙支持式扩弓器会造成更多的第一磨牙及牙槽突倾斜。
[Abstract]:Objective: to compare the clinical effect of maxillary rapid arch expansion with dental support and mixed support arch expander. Methods: the PubMed,Cochrane Library,EMbase,CBM, database of China Zhiwang, Weip and Wanfang were searched by computer, and all the literatures about the rapid maxillary arch expansion with dental and mixed support arch extenders were collected. The retrieval time was from the construction of the database to 2015-10-31. According to the inclusion and exclusion criteria, the quality of the study was evaluated by two researchers and the data were extracted. Meta analysis was carried out with Rev Man 5.3 software. Results: totally 8 studies were included. Meta analysis showed that the angle of the right first molar tilted before and after dilatation [MD=-1.62,95%CI (-3.18, -3.18, -3.18, -3.18, -3.18, -3.18, -3.18, -3.18, -3.18, -3.18] of the right first molar before and after dilatation, respectively. The change of the first premolar distance [SMD=-0.86,95%CI (-1.470.25)] and the obliquity of alveolar process [SMD=-0.86,95%CI (-1.10- 0.20)] were statistically significant. The distance between the first molars [SMD=-0.08,95%CI (-0.61U 0.45)] and the inclination angle of the left first molars (MD=-1.12,95%CI (-2.57U 0.33)] were changed before and after bowing treatment. There was no significant difference in transverse width of maxilla [SMD=-0.30,95%CI (- 1.08 ~ 0.47)]. Conclusion: the effect of dental support and mixed support arch expander on maxillary arch dilatation is similar, and dental support arch dilator will cause more first molar and alveolar obliquity.
