The condition of the orbicularis oris muscle in elderly people with complete loss of teeth using complete removable structures

Abstract

Resume. Masticatory and mimic muscles are one of the components of the gnathological system, which ensures the coordinated work of the chewing apparatus when performing various functions. This is especially important for elderly people who lost their teeth many years ago. Clinical studies have shown that the orbicularis oris muscle+ is involved in both the maintenance of the CRP and the chewing of the food bolus. Since, with long-term use of CRP, there is a decrease in the interalveolar height of the bite, wear of artificial teeth in removable structures. Thus, chewing and facial muscles try to compensate for the above. The determination of their bioelectrical activity allows us to evaluate changes in muscle parameters.
