The relationship between the size of the denture foundation area and the resorption of the alveolar ridge was investigated in 55 edentulous subjects. The denture foundation area was recorded using a modelling compound impression technique with border moulding. Both sides of each edentulous mandible were examined separately, making a total of 110 experimental sides in the study. On a stone cast made from each impression, the size of of the superficial denture foundation area and of the projected denture foundation area on the tentative plane of occlusion of each anatomical zone were measured. The vertical height of the alveolar ridge at the lateral incisor and first molar region was also evaluated. The size of the superficial denture foundation area in the antero-lingual and postero-lingual zones showed no significant correlation with the degree of alveolar ridge resorption. The size of the projected denture foundation area on the tentative plane of occlusion in the anterior section showed negative significant correlation with the degree of alveolar ridge resorption. The size of the projected denture foundation area on the tentative plane of occlusion in the posterior section showed no significant correlation with the degree of alveolar ridge resorption.
在55名无牙颌受试者中研究了义齿基托面积大小与牙槽嵴吸收之间的关系。使用带有边缘整塑的模型材料印模技术记录义齿基托面积。对每个无牙颌下颌骨的两侧分别进行检查，本研究共110个实验侧。在由每个印模制作的石膏模型上，测量每个解剖区域在暂定咬合平面上的表面义齿基托面积和投影义齿基托面积大小。还评估了侧切牙和第一磨牙区域牙槽嵴的垂直高度。前舌侧和后舌侧区域的表面义齿基托面积大小与牙槽嵴吸收程度无显著相关性。前部暂定咬合平面上的投影义齿基托面积大小与牙槽嵴吸收程度呈显著负相关。后部暂定咬合平面上的投影义齿基托面积大小与牙槽嵴吸收程度无显著相关性。
