Bruxism of bruxism. Examples include the "Bruxcore Bruxism-Monitoring Device" (BBMD, "Bruxcore Plate"), the "intra-splint force detector" (ISFD), and electromyographic devices to measure masseter or temporalis muscle activity (e.g. the "BiteStrip", and the "Grindcare"). The ICSD-R listed diagnostic criteria for sleep bruxism. The minimal criteria include both of the following: With the following criteria supporting the diagnosis: "Bruxism" is derived from the Greek word ("brykein") "to bite, "or" to gnash, grind the teeth". People who suffer from bruxism are called "bruxists" or "bruxers" and the verb itself is "to brux". There is no widely accepted definition of bruxism. Examples of definitions include:
Bruxism sleep, the voluntary muscles are inactive due to physiologic motor paralysis, and the jaw is usually open. Some bruxism activity is rhythmic with bite force pulses of tenths of a second (like chewing), and some have longer bite force pulses of 1 to 30 seconds (clenching). Some individuals clench without significant lateral movements. Bruxism can also be regarded as a disorder of repetitive, unconscious contraction of muscles. This typically involves the masseter muscle and the anterior portion of the temporalis (the large outer muscles that clench), and the lateral pterygoids, relatively small bilateral muscles that act together to perform sideways
