Device and method for detection and treatment of bruxism

A device to detect and treat bruxism, comprising;

• a) a set of muscle sensors to measure a series of muscle signals;
• b) a set of brain sensors to measure a series of brain signals;
• c) a biofeedback system to provide a set of biofeedback signals to a bruxer to stop a teeth grinding, the biofeedback system comprising:
• i) a visual feedback system in the form of LED lights;
• ii) an auditory feedback system in the form of sound through a set of speakers, and
• iii) a vibration feedback system through a set of vibrators,
• d) a microprocessor configured to
• i) identify a rhythmic grinding pattern in the series of brain signals and determine a frequency, a phase and an average amplitude of the rhythmic grinding pattern, and activate the biofeedback system with a biofeedback frequency that is the same as the frequency of the rhythmic grinding pattern but have a biofeedback phase shift (time delay) with respect to the phase of the rhythmic grinding pattern,
• ii) randomly change the set of biofeedback signals until the series of brain signals is not rhythmic, and
• iii) change the biofeedback system between the visual, the auditory, and the vibration feedback systems in a cycle of sleep if a temporalis muscle activity or the series of brain signals show a habituation pattern.
