Abstract

Maximum (MOF) and average (AOF) isometric mouth-opening forces were measured with an extra-oral gnathodynamometer in 34 females. Mean MOF and AOF with the teeth in centric relation were respectively 99.6 +/- 22.2 and 89.0 +/- 19.4 N with significant relationships between both MOF and AOF and body mass. Analysis of cephalometric measurements from 22 of the subjects revealed significant relationships between opening force (OF) and certain facial dimensions. In particular, larger OF were associated with features characteristic of an angular facial profile, viz long mandibular base, short mandibular body, large gonial angle and large angle NS-ML.

摘要

用口外测力计对34名女性测量了最大等长张口力（MOF）和平均等长张口力（AOF）。牙齿处于正中关系时，平均最大等长张口力和平均等长张口力分别为99.6±22.2牛顿和89.0±19.4牛顿，最大等长张口力和平均等长张口力与体重之间均存在显著关系。对其中22名受试者的头影测量分析显示，张口力（OF）与某些面部尺寸之间存在显著关系。特别是，较大的张口力与角形面部轮廓的特征相关，即下颌基部较长、下颌体较短、下颌角较大以及NS-ML角较大。
