对全口义齿的组织变化进行了组织学研究。对40例患者在第一磨牙区左侧硬腭，中缝与残脊之间进行了活检。同样的患者在放置合适的义齿3个月后接受检查。40名患者中有30人有反应。在这些患者右侧的同一区域进行了第二次活检。在显微镜检查的基础上，得出以下结论。1. 无牙非义齿佩戴者腭上皮的平均厚度为0.222 mm。2. 佩戴全口义齿3个月后，腭上皮厚度普遍增加。3. 腭上皮细胞的增加在腭突区比在腭突间区更为明显。4. 大多数患者的角蛋白层厚度增加。5. 颗粒细胞层和刺细胞层未见明显变化。6. 口腔黏膜对合适的假牙反应良好。
A histologic investigation to study the tissue changes occurring under complete dentures was done. Biopsies were obtained from 40 patients from the area of left side of the hard palate at the first molar region, midway between the median raphe and the residual ridge. The same patients were examined 3 months after placement of well-fitted dentures. Thirty of the 40 patients responded. A second biopsy was taken from the same area on the right side of these patients. On the basis of the microscopic examination, the following conclusions were drawn. 1. The average thickness of the palatal epithelium of edentulous non-denture wearers was 0.222 mm. in the rete peg region. 2. There was a general increase in the thickness of the palatal epithelium following 3 months of wearing complete dentures. 3. The increase in the palatal epithelium was more marked in the rete peg region than in the inter-rete peg region. 4. There was an increase in the thickness of the keratin layer in most patients. 5. No significant changes were found in the granular-cell layer or the prickle-cell layer. 6. The oral mucous membrane responded favorably to well-fitted dentures.
