As the first step of evaluating the kinematic function and the coordinative movement among articulatory organs, attention was focused on the palatal form in various factors related to the function of pronunciation on complete denture. After the experimental palatal plate was inserted into 13 natural dentitions in the age ranging from 21-24 years old, muscular discharge of intrinsic muscles, tongue movement and mandibular movement before pronunciation were recorded longitudinally. These data were comparatively evaluated with those before insertion of the experimental palatal plate, and the following conclusion were obtained. It has been made clear in this study that from the change of muscular discharge of intrinsic muscles, tongue movement and mandibular movement before pronunciation between before and after the insertion of the experimental palatal plate, correction aspect of the kinematic function and the coordinative movement among articulatory organs varied with point and method of articulation on each sound. And these facts suggested that it was necessary to diagnose and treat under consideration of the relation between the palatal form and articulatory function of tongue and mandible in removable prosthodontic treatment.
作为评估发音功能以及发音器官之间协调运动的第一步，研究重点关注了全口义齿发音功能相关的各种因素中的腭部形态。将实验性腭板插入13名年龄在21至24岁之间的天然牙列后，纵向记录发音前腭部固有肌的肌肉放电、舌运动和下颌运动情况。将这些数据与插入实验性腭板之前的数据进行比较评估，得出以下结论。本研究表明，从实验性腭板插入前后发音前腭部固有肌的肌肉放电、舌运动和下颌运动的变化来看，发音功能的矫正方面以及发音器官之间的协调运动因每个音的发音点和发音方法而异。这些事实表明，在可摘局部义齿修复治疗中，有必要在考虑腭部形态与舌和下颌发音功能之间关系的基础上进行诊断和治疗。
