Efficiency of chewing load deficiency correction in clinical dental practice

Abstract

Weakening of the chewing act, typical for modern humans due to consumption of soft food, causes a deficit of chewing load and has a negative effect on the dental system. To combat hypodynamia of the masticatory apparatus with the aim of preventing destructive processes in its structures, a gnathotraining system was developed, including electrical stimulation of the masticatory muscles themselves in physiological parameters, which develops the effect of “imaginary chewing”, and gnathotraining using chewing gum. In addition, functional training of the masticatory apparatus using chewing exercises was proposed. Considering that chewing gum practically does not compensate for the deficit of chewing load observed in modern society, the staff of the Kazan State Medical University and the Kazan National Research Technological University developed the “Denta Fit” dental trainer and a dental training system. It has been established that dental and jaw training stimulates secretion of saliva, its mineralizing potential, functional resistance of tooth enamel, allows achieving a good level of oral hygiene, reduces the rate of increase in the intensity of dental caries, as well as the severity of muscular-articular disorders of the temporomandibular joints, enhances neuromuscular activity of the masticatory muscles and regional blood flow. In children with permanent bite, dental and jaw training maintains the hydrogen index (pH) of oral fluid at a neutral level and provides, in combination with a toothbrush, optimal hygienic dental care, contributes to the formation of a correct dental occlusion. Thus, the effects of increased neuromuscular activity of the masticatory muscles, as well as regional vascular tone, arising during dental and jaw training, indirectly indicate that the dental and jaw system receives adequate mechanical loads necessary for the normal functioning of all its links. The results of the conducted studies indicate the effectiveness and feasibility of using dental training to improve dental status, which serves as a new approach to the prevention and treatment of dental diseases.
