97 of both sexes (males - 38 and females- 59) at the age of 75-90 years were analyzed. Among them, 58.74% patients used prosthetics firstly, 41.26% previously used complete removable dentures. During examination of the oral cavity in 61.85% bone formation was revealed and in 27 (45.00%) presented acute maxillofacial line from one or other sides, in eight (13.33%) with palpation or visual examination exostoses was revealed, 12 (20.00%) presented palatal torus of different size and length, in three (9.27%) sharply protruding lingual awn was revealed. In 88 (90.72%) patients the mucosa of the alveolar processes and the hard palate was dense, not amenable, and only in nine (9.31%) its vertical compliance in the posterior third of the hard palate was noted, in 10 (10.36%) patients there was A mobile alveolar ridge, in six (6.18%) - maceration of the skin and even cracks were observed in the corners of the mouth. When studying the psychological changes in geriatric patients it was found that 66 (68.04%) had a balanced, harmonious personality type, 25 (25.77%) presented uncertain, and asthenic, excitable, sensitive type and had a negligible percentage of the total number of patients. Among 97 patients with geriatric age with complete loss of teeth in 57 cases (58.76%) hypertension was present, in 28 patients (28.86%) ischemic heart disease, arterial hypertension were present, in 26 (26.80%) chronic disorder of the cerebral circulation was revealed. Also in the anamnesis it was noted that 23 (23.71%) patients presented such diseases as type 2 diabetes, glaucoma, arterial hypertension and 22 patients (22.68%) had stomach and duodenal ulcers and gastritis. The presence of a large percentage of general somatic pathology in elderly patients with complete loss of teeth and a combination of two or three diseases indicates a decrease in the compensatory capacities of the aging organism. The study of the anamnesis of diseases revealed the causes of tooth loss. Thus, in 20 (21.62%) patients teeth were removed due to caries and its complications, in 77 (78.38%) the causes were combined: tissue diseases, somatic pathology and others. To access the jaws according to Schroeder and Keller, the predominance of type II atrophy was established at the bottom and I- at the upper. Ie, the conditions for prosthetics on the upper jaw were favorable, and on the lower one were not favorable to prosthetics. Clinical observations of geriatric patients prove that the lack of attention to the patient's state of mind, disregarding the need to establish the type of their personality before orthopedic intervention often leads to unfavorable consequences.
