Sleep bruxism is an oral parafunction characterized by grinding or clenching the teeth during sleep that is associated with an excessive sleep arousal activity.
Recent studies have shown that sleep bruxism features a typical muscular activation pattern (i.e., rhythmic masticatory muscle activation [RMMA] ) which is usually associated with arousals of autonomic nervous system. Bruxoff is the first portable system that can exactly identify this typical muscular activation.
The recording of the signal can be done by the patient during the night, at home. Thanks to the innovative Bruxmeter software the dentist can display the results of the automatic analysis and make a diagnosis in a simple and fast way.
Bruxoff uses the CoDe electrodes to detect surface electromyographic signals from the masseter muscles. These innovative electrodes offer two big advantages with respect to traditional electrodes:
1. they permit an easy application avoid orientation problems to the patient
2. they can exactly record the activity of the masseter muscle with a consequent high quality signal analysis
Scientific studies have shown that Bruxoff is a user-friendly device able to detect sleep bruxism in a very precise way. Considering the polysomnographic data as the gold standard, the sensitivity and specificity of Bruxoff automatic measurement were 92% and 85%, respectively.
