Using strain-gauged maxillary complete dentures, the effects of the surgical removal of soft mobile tissue over the maxillary edentulous alveolar ridges--flabby ridges--on the deformation pattern and magnitude of functional strain were studied in five subjects. The results showed that a 20-90% reduction in denture deformation had taken place after surgery. Furthermore, a pre-operative shear-straining pattern of the buccal flanges and the lateral palatal slopes was not evident post-operatively. The results of this study point on the beneficial value of early surgical removal of flabby maxillary alveolar ridges.
使用应变片式上颌全口义齿，在五名受试者中研究了上颌无牙牙槽嵴（松软牙槽嵴）上软组织的手术切除对义齿变形模式和功能应变大小的影响。结果显示，术后义齿变形减少了20%至90%。此外，术前颊侧翼缘和腭侧斜坡的剪切应变模式在术后并不明显。本研究结果表明早期手术切除上颌松软牙槽嵴具有有益价值。
