The purpose of this study was to evaluate speech disorder improvement by the maxillary prostheses of which palatal shape were modified utilizing the palatography in the patients with maxillary defect after surgery.The palatal contour of the prostheses were examined using "Palatography including teeth" and modified so as to show proper tongue-to-palate and teeth contact. The artificial palates made of black vinyl seat covering the palate and occlusal surfaces of maxillary teeth were coated with white alginate powder and inserted into the mouths of the subjects. After pronunciation of test sound, the tongue contact areas were demonstrated by wetting of powder. Each subject's five samples of same sound were averaged by the image processor system. The test sounds were voiceless plosive, voiced plosive and flapped sounds.Changes in speech of subjects before (BT) and after insertion of the maxillary prostheses (AT) were evaluated by the articulation tests : (1) The acoustical speech articulation test ; (2) the nasality measured by Nasometer (Model 6200-2) with reference to the nasalance scores, threshold, time history ; (3) voice print analyzed by a sound spectrograph (sonagram).The subjects were ten normal dentulous adults and five patients with maxillary defect by operation. They were classified into three groups according to the extent of the defect : Class I ; within hard plate (two). ClassII ; including soft plate (one). ClassIII ; reaching as far as posterior border of soft palate (two).The results were as follows :1. The articulation test score were low in BT., but became higher in AT..2. The nasalance scores of classI, II in BT. were high, but that in AT. were fairly close to that of normal subjects. In classIII, the scores were higher than that in classI, II.3. Abnomality of the sonagram decreased in AT. of classI, II, but in classIII, it showed a little improvement.

本研究的目的是评估在上颌骨缺损患者术后，利用腭造影术对修复体的腭部形状进行修改的上颌骨修复体对语音障碍的改善情况。使用“包括牙齿的腭造影术”检查修复体的腭部轮廓，并进行修改，以显示适当的舌腭和牙齿接触。将覆盖腭部和上颌牙齿咬合面的黑色乙烯基座制成的人工腭涂上白色藻酸盐粉末并插入受试者的口中。在发出测试音后，通过润湿粉末来证明舌接触面积。每个受试者的五个相同声音样本由图像处理器系统平均。测试音为清塞音、浊塞音和瓣音，通过语音清晰度测试（1）语音清晰度测试（2）鼻音测量仪（Nasometer）测量受试者安装上颌义齿前后的语音变化（3）声谱仪声纹分析。根据缺损程度将其分为三组：I类;硬钢板内（2例）。II类;含软板（1个）。Ⅲ类：远及软腭后缘（2例）。BT组的清晰度测试得分较低，但在AT中变得更高。2. BT Ⅰ、Ⅱ级鼻平衡评分。很高，但在AT。与正常人的情况相当接近。Ⅲ级患者的得分高于Ⅰ、Ⅱ级患者。AT的声图异常减少。I、II级，但III级，它显示出一点改善。
