[Morphological data on gerontostomatology]

On the base of the study of serial histological sections, freezed-sections and special bone-praeparates senile alterations of the structure of the palatine mucosa and the mandibular bones are discussed, with special regard on the gerontostomatological aspects. After the loss of the teeth the structure of the connective tissue of the gingiva diappears, in the processus alveolaris develops fibrosis. The glandular tissue of individual extension on the edges shows regression. Thickening of the epithelium in some area can be seen. The lamina propria in the anterior third is very thick in the pharyngeal part becomes thinner. Alveolar processes of the maxilla show signs of involution and atrophy of disuse, with a number of defects and assymetries on the palate. On the macrorelief of the mandibula characteristic changes can be observed: in the region of the corpus eburneationg and osteosclerosis of the spongiosa can be revealed.
