The first step of clinical management of the temporomandibular disorders (TMD)is to distinguish the origin of
problem, to classify into myogeneous and joint problems, which have been regarded to be an important process.
Although the precise mechanisms for the symptoms or pathology of these conditions have not yet been clarified,
muscular parafunction or hyperfunction has been regarded to play an important role in the etiology of TMD. Excess
mechanical loading to the temporomandibular joint (TMJ) has been reported to be one of the possible causes for the
development of osteoarthritis. These forces might be exerted through mandibular parafunctions like sleep bruxism or
tooth contacting habit. For clinical control of sleep bruxism, a thick palatal appliance which fills the palate and does
not cover the occlusal surface have been developed. In this review article, clinical implication of the relationship
between occlusion, mastication and bruxism have also been discussed.
