背景双种植体覆盖义齿（2-IODs）是一种预期的治疗选择，以改善咀嚼性能（MP）的无牙颌个人。目的：本研究的目的是比较即刻负载和常规负载的磁性附着体固位的下颌2-IOD之间的MP。材料与方法19例无牙颌患者随机分为即刻加载组和常规加载组。每个参与者接受两个植入物。即刻组在种植体植入当天加载，而常规组在种植体植入后3个月加载。在基线和种植体植入后1、3、6、12、24和36个月，评估了通过变色口香糖和胶质果冻测量的MP和最大咬合力。结果在6个月的时间点观察到即刻组的MP显著较高（P = 0.034）。在任何时间点，两组之间通过咀嚼口香糖测量的MP或最大咬合力均无显著差异。结论在本研究的范围内，即刻负荷2-IODs比常规负荷2-IODs能在更早的时间点改善MP。
Background Two-implant overdentures (2-IODs) is an expected treatment option to improve the masticatory performance (MP) of edentulous individuals. Purpose The purpose of the current study was to compare MPs between immediately loaded and conventionally loaded mandibular 2-IODs retained by magnet attachments. Materials and Methods Nineteen participants with edentulous mandibles were randomly assigned to an immediately loaded group or a conventionally loaded group. Each participant received two implants. The immediate group was loaded on the same day as implant insertion, whereas the conventional group was loaded 3 months after implant insertion. Both MP, measured by a color-changeable chewing gum and a gummy jelly, and maximum occlusal force were assessed at baseline and at 1, 3, 6, 12, 24, and 36 months after implant insertion. Results A significantly higher MP, measured by gummy jelly, was observed at the 6-month time-point in the immediate group (P = .034). No significant differences in MP, measured by chewing gum, or maximum occlusal force were observed between the two groups at any time-point. Conclusions Within the limitations of the present study, immediate loading of 2-IODs could improve MP at an earlier time-point than conventional loading of 2-IODs.
