Abstract:

In the normal social and personal environment each person performs functions needed for its existence and development. These functions like eating, chewing, talking and more are a natural act. They are a vital necessity. In some cases, man also performs unnatural, unnecessary actions for its normal developmental activities and functions that are known as parafunctions. The parafunctions in the chewing area can be divided to: occlusal type – with the active involvement of the occlusal dental surface, non-occlusal type – with the active involvement of the lips, the cheeks and the muscles, of course not without the involvement of the dental surfaces. One of the main and often occurring parafunction of the occlusal type is bruxism.
