Many cases of mandibular lateral deviation in adults, while having contributory factors such as malalignment of teeth and poor dental habits during the development stage of a normal lifestyle, are believed to be the result of adaptations made to activate the stomatognathic function as fully as possible.<BR>Conversely, in addition to the primary functions of functional occlusion such as mastication, speech, respiration, esthetics and maintaining posture, some also advocate the function of stress management through bruxism. Recently, various dynamic adaptation strategies of the body to stress are reported to be relieved through the process known as allostasis, and it has been suggested that maintenance of allostasis in the body is a further function of occlusion.<BR>The treatment of mandibular lateral deviation can be achieved with a total jaw occlusion reconstruction, combining corrective treatment with crown restoration/crown prosthesis treatment. Through corrective treatment, the mandibular position can be easily changed, although the skeletal morphology is difficult to change. Further, while the occlusal plane, tooth configuration, and tooth axis can be altered through corrective treatment, crown configuration does not change. The existence and degree of problems associated with each of these aspects must therefore be accurately understood, and it is necessary to perform treatment that considers the body's adaptation response.
