项目摘要

The objective of this study was to clarify the characteristics of lip-closing force (LCF) measured by the multidirectional LCF measurement system. In 139 subjects, LCFs in eight directions during maximum voluntary pursing-like lip closure tasks, height, body weight, handgrip strength, dental status and the usage of removable denture were recorded. Summed value of LCFs for all eight directions (total LCF [TLCF]) in male was significantly greater than that in female. The directional LCF (DLCF) was large by vertical, oblique and horizontal directions order. No significant correlation between opposing DLCFs was observed in 3 pairs in male and the symmetric DLCFs were not observed from 4 pairs in female. The significant weak correlation between TLCF and height, body weight were observed in male not in female. TLCF was not statistically related to the number of residual teeth or vertical occlusal support and the preservation of all anterior teeth in both genders. In male, TLCF in the subjects with denture wearing was significantly greater than that without denture wearing.

摘要本研究旨在探讨多方向唇缘闭合力量测系统所量测之唇缘闭合力特性。在139名受试者中，记录了最大自主性类似于闭合嘴唇的任务中8个方向的LCF、身高、体重、握力、牙齿状况和活动义齿的使用情况。男性8个方向的LCF总和（总LCF [TLCF]）显著大于女性。方向性LCF（DLCF）按垂直、斜向和水平方向排列。3对男性的相对DLCF之间无显著相关性，4对女性的对称DLCF之间无显著相关性。男性TLCF与身高、体重呈极显著的弱相关，女性TLCF与身高、体重无显著相关。在两种性别中，TLCF与剩余牙数或垂直咬合支持以及所有前牙的保存均无统计学相关性。在男性中，戴义齿组的TLCF显著高于不戴义齿组。
