摘　　要：目的:探讨磁性附着体在下颌全口覆盖义齿中的直用价值。方法:用磁性附着体为17例患者制作下颌全口覆盖义齿,粘固磁体前、后,进行最大咬合力、固位力和咀嚼效率测试,并比较2基牙和3基牙磁性附着体全口覆盖义齿的功能效果。采用SPSS13.5软件包对数据进行单因素方差分析。结果:粘固磁体后,全口覆盖义齿的最大咬合力、固位力和咀嚼效率显著提高(P<0.01);3基牙磁性附着体全口覆盖义齿与2基牙者相比,最大咬合力和咀嚼效率差异无显著性(P>0.05),但固位力显著提高(P<0.01)。结论:应用磁性附着体下颌全口覆盖义齿能有效改善覆盖义齿的咬合力、同位力和咀嚼效率;2基牙磁性附着体制作下颌全口覆盖义齿具有良好的临床应用价值。PURPOSE： To evaluate the clinical usefulness of magnetic attachment in mandibular complete overdentures. METHODS： Seventeen patients were treated with Magnetic EX retained mandibular complete overdentures. The maximal masticatory force, retention and masticatory efficiency of mandibular complete overdentures with 2 or 3 Magnetic EX attachments were investigated at different periods. SPSS13.5 software package was used for statistical analysis. RESULTS： The results showed mandibular complete overdentures with magnetic attachments increased the masticatory force, retention and masticatory efficiency （P〈0.01）. Mandibular complete overdentures with 3 nmgnetic attachments provided better retention than those with 2 magnetic attachments （P〈0.01）, but the masticatory force and masticatory efficiency didn＇t increase significantly （P〉0.05）. CONCLUSIONS： Mandibular overdentures supported by magnetic attachments can be used to improve the maximal masticatory force, retention and masticatory efficiency. Mandibular overdenture with 2 magnetic attachment has more value in clinic.
