Abstract
Resume. The article presents the results of a long-term examination of prosthetics in 100 patients aged 55 to 73 years with a complete absence of teeth in the lower jaw, of which 62 were made removable dentures based on intraosseous implants with installed bol-abutments, and 38 patients were made removable dentures with based on intraosseous implants with an installed beam structure. A significant superiority of prosthetics based on a beam structure, was revealed in terms of quality of life, fixation of prostheses, as well as functional efficiency. At the same time, when using implants with installed large abutments, a large degree of atrophy of the alveolar part in the distal parts of the mandible was registered. The results obtained indicate the need for further research, in particular, by studying stress-strain states, in order to develop an algorithm for determining indications for various types of prosthetics in patients with a complete absence of teeth in the lower jaw. Key words: complete edentulous mandible, bol-abutment, bar constructionthe level of quality of life, the effectiveness of treatment.
