The author noticed the relation between articulatory functions and the prosthesis. For the purpose of clarifying the influence of the insertion of denture on the duration of speech sound and the articulatory functions before pronunciation and on the self-compensation of these organs. The experimental palatal plates were inserted on 13 subjects with natural dentition, assuming that they were inserted with complete denture, and the duration of speech sound, muscular discharge of facial muscle and tongue pressure before pronunciation were evaluated longitudinally with the pre-insertion of palatal plate as basis. As the result of this study, the following conclusions were obtained. The results of this study suggest that speech sound, lips and tongue being important organs as the articulators are placed under strong influence before pronunciation by insertion of the denture, whereas on the self-compensation of the articulators before pronunciation differed according to the point of articulation and the manner of articulation of each speech sound. Therefore, it was necessary to take care on the relation between the shape of palatal plate and the articulatory functions of lips and tongue in the clinical prosthodontics.
作者注意到发音功能与修复体之间的关系。为了阐明义齿的戴入对语音时长、发音前的发音功能以及这些器官自我代偿的影响。将实验性腭板戴入13名天然牙列受试者口中，假定他们戴的是全口义齿，并以戴入腭板前为基础，纵向评估语音时长、面部肌肉的肌电发放以及发音前的舌压力。作为本研究的结果，得出了以下结论。本研究结果表明，作为发音器官的语音、嘴唇和舌头在发音前会受到义齿戴入的强烈影响，而发音前发音器官的自我代偿因每个语音的发音部位和发音方式而异。因此，在临床口腔修复学中，有必要关注腭板形状与嘴唇和舌头发音功能之间的关系。
