材料与方法：2名受试者参与本研究。换能器和实验上层结构已经调整到受试者的咬合方案，用钛螺钉连接到种植体上。被测试的食物是口香糖和花生。结果：咀嚼花生时种植体每次咀嚼周期的平均最大负荷明显高于咀嚼口香糖时。咀嚼花生时最大负荷方向比咀嚼口香糖时更分散。咀嚼花生时，各咀嚼周期力增加阶段的负荷方向变化幅度明显大于咀嚼口香糖时。结论：两组受试者的种植体负荷均受食物质地影响。这种测量方法可以用于研究咀嚼过程中种植体的负载调制机制。
Materials and Methods:Two subjects participated in this study. The transducer and the experimental superstructure, which had been adjusted to the subject's occlusal scheme, were attached to the implant with a titanium screw. The foods tested were chewing gum and peanuts.Results:The mean maximum load on the implant in each chewing cycle was significantly higher during peanut chewing than during gum chewing. The direction of maximum load was significantly more widely dispersed during peanut chewing than during gum chewing. The range of changes in load direction during the force-increasing phase of each chewing cycle was significantly wider during peanut chewing than during gum chewing.Conclusions:The load on the implant was affected by food texture in both subjects. This measurement method can be useful to investigate the mechanisms of load modulation on implants during mastication.
