The purpose of this study was to investigate the influence of the thickness of soft lining materials on clinical evaluation, and the relation between clinical evaluation and thickness of oral mucosa.After obtaining informed consent, 4edentulous patients participated in this study. The thicknesses of soft lining materials based on test-dentures were 1mm and 2mm. The thicknesses of oral mucosa was measured using SDMI The test-dentures were clinically evaluated by measuring masticatory performance by the sieving method, and the value of the occlusal contact area, occlusal force and stability of track of center offorce using T-Scan II system.The results were as follow1.The thicknesses showed a tendency to be thinner on the lingual side rather than at alveolar crest2.The thickness of soft lining materials has no influence on the masticatory performance.3. There were no significant difference between the value of the occlusal contact area and that of the ocelusal force between 1mm and2 mm thicknesses.4.Only a minor relation was found between the clinical evaluation and the thickness of oral mucosa.

本研究的目的是探讨软衬材料厚度对临床评价的影响，以及临床评价与口腔粘膜厚度的关系。在获得知情同意后，4名无牙颌患者参与了本研究。基于测试义齿的软衬材料厚度为1mm和2mm。采用SDMI测量口腔粘膜厚度，采用筛分法测量咀嚼性能，采用T-Scan II系统测量咬合接触面积、咬合力和力心轨迹稳定性值，对试验义齿进行临床评价。结果如下：1、舌侧厚度较牙槽嵴处有变薄的趋势；2、软衬材料的厚度对咀嚼功能没有影响。性能.3. 1mm和2mm厚度之间的咬合接触面积值和咬合力值没有显着差异。4.临床评价与口腔粘膜厚度之间仅存在较小的相关性。
