In order to evaluate the role of magnetic retainers for the retention of complete overdentures, the authors applied self-made measuring instrument and absorbent methods to measure the real retentive force and masticatory efficiency quantitatively at pre- and post installation of magnetic retainers in the complete overdentures. The results showed that the retentive force of the denture in the mouth increased about 1500g which was 78.95% measured extraorally; the masticatory efficiency of the patients was 1/3 higher after installation of magnetic retainers in the dentures than before which meant that the denture fitting time of the patient could be shortened.
为了评估磁性固位体在全口覆盖义齿固位中的作用，作者应用自制测量仪器及吸光度法，在全口覆盖义齿安装磁性固位体前后，对其实际固位力及咀嚼效率进行了定量测量。结果显示，义齿在口腔内的固位力增加了约1500g，为口外测量值的78.95%；义齿安装磁性固位体后患者的咀嚼效率比安装前提高了1/3，这意味着患者的义齿适应时间可以缩短。
