Microscopic examination was done of biopsy material of hard palate mucosa in healthy subjects with normal teeth and in edentulous patients with a long history of complete upper prostheses. The examination in transmission electron microscope included cells of the multilayer flat-cell epithelium of the mucosa covering the hard palate. Isolated cilia were found in the cells of the germinative layer and in the lamina propria of the mucosa where they penetrated from the epithelium across the basement membrane. The cilia were present in a significantly higher number of cells in hard palate epithelium subjected to long-term pressure exerted by the prosthesis. On the basis of observations of the structure of cilia and its environment one may assume that this apparatus may serve as an epithelial receptor of local changes produced by long-term and changing pressure of the mucosa through the mediation of masticatory forces transmitted onto the mucosa by the plate of the prosthesis.
对牙齿正常的健康受试者以及佩戴全口上颌义齿历史较长的无牙患者的硬腭黏膜活检材料进行了显微镜检查。透射电子显微镜检查包括覆盖硬腭的黏膜多层扁平上皮细胞。在生发层细胞和黏膜固有层中发现了孤立的纤毛，纤毛从上皮穿过基底膜进入固有层。在长期受义齿压力的硬腭上皮细胞中，纤毛存在于数量明显更多的细胞中。基于对纤毛结构及其周围环境的观察，可以推测该结构可能作为一种上皮感受器，通过义齿托传递到黏膜上的咀嚼力介导，感受黏膜长期变化压力所产生的局部变化。
