This study was conducted to determine the effectiveness of orthodontic appliances in improving cerebral
circulation. The 24 participants of the study underwent a rheoencephalographic examination before and during the use
of mouth guards. Its results analysed the changes in blood filling and blood flow in the brain vessels and evaluated the
dynamics of treatment. According to the results of the study, insignificant, and slight positive treatment dynamics were
detected in 58.33% of the subjects, no negative dynamics were detected, and no significant changes were recorded in
41.67% of the participants. This effect of orthodontic appliances on improving cerebral circulation is explained by the
fact that by alleviating the symptoms of craniomandibular dysfunction, they affect the balance of the centre of gravity of
the skull, reduce tension and spasm in the neck muscles, and protect the joints from mechanical irritation, which helps
to reduce vascular tone and improves blood filling and blood flow in the masticatory muscles and jaw joint. The blood
filling of the chewing muscles and jaw joint has no direct connection with the blood filling of the brain vessels, as these
structures are supplied from different arteries, However, a decrease in vascular tone in the craniomandibular system and
in the muscle bed of the cervical spine can affect blood pressure reduction and venous outflow in the jaw joint, which
will indirectly improve cerebral circulation. The obtained results indicate that orthodontic problems can be factors of
deterioration of blood filling and blood flow in the vessels of the brain, so the use of mouth guards is an effective method
that should be used in the complex treatment of patients with cerebral circulation disorders
