本研究评估了一种测量咀嚼性能的筛选方法，并确定了咀嚼性能和咀嚼下颌运动之间的关系。10名有牙齿的成年人和3名全口义齿佩戴者参加了这项研究。在10 s咀嚼序列和另一个以吞咽阈值结束的序列后确定这些受试者的咀嚼性能指数。使用杏仁作为测试食物，并使用标准的0.65 mm见方尺寸的黄铜丝筛对杏仁碎片进行筛分。咀嚼下颌运动的同时记录的光电设备。咀嚼性能测试的再现性良好（10 s和吞咽阈值测试指标分别为r = 0.98和0.82）。有牙者与戴义齿者的咀嚼效能指标有显著差异。有牙列受试者的10 s咀嚼性能指数与下颌骨速度的所有参数均表现出中度至相当强的相关性（r = 0.6-0.7）。10 s指数与咬合水平阶段的持续时间和咀嚼周期的总持续时间呈强负相关（r = -0.7 ~-0.8）。这项研究证实，咀嚼性能水平是相对稳定的，并与特定的咀嚼下颌运动参数的疗效。
This study evaluated a sieve method for measuring masticatory performance and determined the associations between masticatory performance and masticatory mandibular movements. Ten dentate adults and three complete denture-wearing subjects participated in the study. The masticatory performance indices for these subjects were determined after a 10 s masticatory sequence and another sequence that ended at the swallowing threshold. Almond was used as the test food and almond fragments were sized using a standard 0.65 mm square size brass wire sieve. Masticatory mandibular movements were simultaneously recorded by an optoelectronic device. The reproducibility of the masticatory performance tests was good (r = 0.98 and 0.82 for the 10 s and swallowing threshold test indices, respectively). The masticatory performance indices were markedly different between dentate and denture-wearing subjects. The 10 s masticatory performance index in the dentate subjects, showed moderate to rather strong correlation with all parameters of mandibular velocity (r = 0.6-0.7). The 10 s index also showed a strong negative correlation to the duration of the occlusal level phase and the total duration of the chewing cycle (r = -0.7 to -0.8) in the dentate subjects. This study confirms that masticatory performance levels are relatively stable and associated with the efficacy of specific masticatory mandibular movement parameters.
