Decrease in the interalveolar distance (IAD) that develops during a period of permanent occlusion as a result of progressive primary dental diseases: Increased abrasion of hard tissues of the teeth, extensive edentulous space, and generalized form of periodontitis is accompanied by morphofunctional changes in the masticatory muscles and the development of temporomandibular joint dysfunction. The objective of the study was to identify development mechanisms of the reduced occlusion syndrome that develops as a result of decrease in the IAD caused by primary dental disease
