後牙錯咬之擴張矯正治療模式:系統性回顧

THE ORTHODONTIC EXPANSION TREATMENT OF POSTERIOR CROSSBITE-A SYSTEMIC REVIEW

摘要


本篇目的是以實證醫學方式評估比較不同種類上顎擴張方式對後牙錯咬改善率是否有差異。研究選擇條件以上顎擴張治療後牙錯咬的隨機對照試驗(Randomized Controlled Trial, RCT),從Medline上搜尋72篇,共有十篇符合條件,其中五篇具較低偏差風險(Bias risk),如Martina R et al. (2012)、Petrén S et al. (2008)、Petrén S et al. (2011)、Godoy F et al. (2011)、McNally MR et al. (2005)等。結果顯示,快速上顎擴張和慢速上顎擴張在治療後牙錯咬的效果上沒有顯著差異,四環擴張器(Quad-helix)的表現較活動式擴張板(Removable expansion plate)好,混合齒列時期的後牙錯咬不會產生自發性改善。

並列摘要


The purposes of this literature review were to evaluate and compare the correction rate of posterior crossbite of different kinds of maxillary expansion. The study selection criteria included RCTs involving subjects with posterior crossbite with maxillary expansion which searched from MEDLINE. The search strategy resulted in 10 articles that fitted to the inclusion criteria from 72 searched papers. Five out of ten articles have low bias risk, which are Martina R et al. (2012), Petren S et al. (2008), Petren S et al. (2011), Godoy F et al. (2011), McNally MR et al. (2005). The result showed there were no significant difference between RME and SME on treating posterior crossbite. Quad-helix showed better result than removable expansion plate. Posterior crossbites did not be spontaneously corrected during the transition into the permanent dentition.
