Kennedy I类（KC I）患者的咀嚼优势尚未得到很好的定义。本研究旨在探讨KC I患者的咀嚼优势和咀嚼性能，包括剩余后牙和可摘局部义齿（RPD）治疗的意义。入选左右两侧后牙数量存在差异（D+）的KC I患者和无差异（D-）的KC I患者。健康的齿状（HD）受试者也登记为阳性对照。咀嚼优势，定义为咀嚼优势指数（MPI;范围0-100%）计算从肌电图活动在自愿咀嚼，咀嚼性能进行了评价，在前和后RPD治疗。KC I D+组的Pre-MPI显著高于HD组。RPD治疗能显著改善KC I组的MPI和咀嚼效能。然而，无论RPD治疗如何，每个KC I组和HD组之间的咀嚼性能存在显著差异。认为KC Ⅰ型患者的咀嚼优势受剩余后牙数目差异的影响。RPD治疗可改善KC I患者的咀嚼优势和咀嚼效能，但后者与HD组的差异不显著。
Mastication predominance in Kennedy class I (KC I) patients has not been well defined. This study aimed to investigate mastication predominance and masticatory performance in KC I patients, including the significance of remaining posterior teeth and removable partial-denture (RPD) treatment. KC I patients who had differences in the number of posterior teeth between left and right sides (D+) and KC I patients who had no differences (D−) were enrolled. Healthy dentate (HD) subjects were also registered as a positive control. Mastication predominance, defined by mastication predominance index (MPI; range 0–100%) calculated from electromyogram activities during voluntary chewing, and masticatory performance were evaluated at pre- and post-RPD treatment. Pre-MPI in KC I D+ was significantly higher than in HD. RPD treatment could significantly improve MPI and masticatory performance in both KC I groups. However, there were significant differences in masticatory performance between each KC I group and HD, regardless of RPD treatment. It was considered that the mastication predominance in KC I patients was affected by the difference in the number of remaining posterior teeth. RPD treatment could improve mastication predominance and masticatory performance in KC I patients, although the latter was not similar to HD group.
