Chronic temporomandibular disorder (TMD) patients, specifically those with severe symptoms, shows a reorganized activity, mainly resulting in worsening functional performances. Mastication is one of the most important vital functions of human being. This disorder can cause people to swallow food without chewing enough & they have more digestive complaints (in terms of the cost of medical treatment) than a comparable normal group.

The fundamental quantity in mastication analysis is the chewing cycle, representing the motion of the lower jaw from the point where teeth come closer to open and vice versa. In this, a magnet attached onto the lower front teeth and using a software, record video movie of movements of the magnet together with the lower jaw.

The analysis of the patterns of chewing in the onset of treatment and later in the course of treatment will provide us concrete information on the success of the treatment.
