The histologic tissue changes of the residual alveolar ridges were studied in five edentulous patients ranging from 55 to 80 years of age. The material studied was obtained from cadavers. The following observations were made: (1) The epithelium was hornified. Acanthosis was found in all specimens. (2) In four of the specimens, the collagen fibers covering the residual bone crest showed a hyalinized area. (3) Mucoid collagen degeneration was seen in all specimens. (4) The most striking finding, common to all specimens, was the epithelial remnants. Resting and proliferating types were identified. (5) Chronic inflammation was found in all specimens. (6) Both osteoid and necrotic bone types were observed. (7) An outstanding characteristic of the residual alveolar ridge was the reinforcement of the internal structure of the bone by endosteal apposition.
对5名年龄在55岁至80岁之间的无牙患者的残余牙槽嵴的组织学变化进行了研究。所研究的材料取自尸体。得到了以下观察结果：（1）上皮角化。在所有标本中均发现棘层增厚。（2）在4个标本中，覆盖残余骨嵴的胶原纤维出现透明化区域。（3）在所有标本中均可见黏液样胶原变性。（4）所有标本共同的最显著发现是上皮残余。识别出了静止型和增殖型。（5）在所有标本中均发现慢性炎症。（6）观察到类骨质和坏死骨类型。（7）残余牙槽嵴的一个突出特征是通过骨内膜附着加强了骨的内部结构。
