目的：磁性附着体可用于各种口腔修复应用。然而，在过去几年中，随着其使用的增加，注意到了一些问题。在这项研究中，与磁性附着体在口腔修复的挑战进行了总结，根据收集的数据超过8 year periods.Materials和方法：77例患者覆盖义齿和磁性附着体，观察1992年11月至2000年8月在大坂齿科大学医院。通过Kaplan-Meier生存分析分析问题发生与时间的关系。结果：37.1%的基牙和30.6%的基托存在问题;结论：磁性附着体可以帮助改善义齿固位，但颌骨切除的情况下，已被切除的肿瘤进行显着不如传统的覆盖dents.Conclusion。
Purpose : Magnetic attachments are available for various prosthodontic applications. However, several problems have been noted over the past few years as their use has increased. In this study, the challenges associated with magnetic attachments in prosthodontics are summarized, based on data collected over an 8-year period.Materials and Methods : Seventy-seven patients with overdentures and magnetic attachments were observed from November 1992 to August 2000 at Osaka Dental University Hospital. The relationship between the occurrence of problems and time was analyzed through the use of the Kaplan-Meier survival analysis. The prognostic factors were classified into two categories : complete vs. partial dentures, and conventional dentures vs. dentures for resected jaws, which were the compared using the Log rank test at a significance level of 0.05.Results : Problems were noted for 37.1% of the abutment teeth and 30.6% of denture bases. The overdentures placed in cases where jaws had been resected for tumor removal performed significantly worse than conventional overdentures.Conclusion : Magnetic attachments might help to improve denture retention, except for cases where jaws have been resected.
