Named after a study by scientists from Saratov State Medical University (SSMU). VI Razumovsky, braces and aligners change the structure of the activity of the cerebral cortex. results published In European Physical Journal Special Topics (EPJST).
During the study, scientists from SSMU examined changes in brain activity before and after starting teeth straightening using braces or aligners in patients without severe pain syndromes. To do this, they used electroencephalography, a research method in which electrical potentials arising in the cerebral cortex are recorded by a device and recorded on paper tape.
The results showed that when wearing braces, changes in the number of electrical activity patterns in the brain were observed in high-frequency areas in the cerebral cortex. Light correction with aligners results in a significant reduction in the number of activity patterns in these ranges.
According to scientists, this is due to the strong impact of braces and aligners on the sensors and bone structures of the face and oral cavity. Partial changes in the soft tissues of the face affect the activity of nerve fibers and related structures, which transforms the functional activity of the brain.
