【摘要】 目的引入动态的图象测里概念，进行口周软组织移动量的测量。方洁利用已开发的计算机图象处理系统．对三种测定条件下口腔周围软组织的移动量进行测量研究。结果（1）发／mo／时，口唇突出，上唇的测定点向上内前方．下唇的测定点向下内前方动作，因此．唇上三角形面积变化的大小依次为M3<M2<M1。（2）发／si／时，由于元音／i／的影响，下唇向后下方的移动量＞／o／，从而使唇下三角形面积大小依次分布为M3＞M2＞M1。结论发音是口腔三大功能之一，作为一种研究手段，能有效地进行动态测量。更多还原

【Abstract】 Objective This article introduced a concept of dynamic image measurement for calculate the quantity of circumoral soft tissue movements. Methods A developed computer image analyzing system was used to calculate the quantity of circumoral soft tissue movements under the three conditions. Results (1)When/mo/is pronounced,lip protrudes, the upper lip landmarks move upwards. inwards and forwards,and the lower lip landmarks downwards and backwards. The variation of upper lip triangular area will be M2<M3<M1.that of the lower lip will be M3>M2>M1. (2)When/si/is pronounced,as a result of vowel, the amount of lower lip moving down backwards is more than that when/mo/is pronounced, which makes the lower lip triangular area comes to be M3 > M2 > M1. Conclusion Pronunciation is one of the important oral functions. It could be used as a method of resarch to measure the facial soft tissue change dynamically and effectively. [更多还原
