TÍULO: Portal to Craniomandibular Orthodontics based on the concept of Occlusion Medicine and Polyvagal Theory

Research results had done by Kanagawa occlusion medicine project showed the close relationship between the masticatory organ, brain function, and the stress pathways, it has become even more important to progress toward this new research area that lies at the interface between stress medicine and occlusion dentistry and to synthesize new entity called occlusion medicine. This field of research promises to contribute not only to dentistry but also to psychosomatic medicine as new concepts in the healing arts. Stephen Porges proposed his philosophy of autonomic nervous system, the polyvagal theory, which explain newly developed autonomic nervous system (ANS) as neurophysiological foundations of emotions, attachment, communication, and self-regulation, the social engagement system. The social engagement system has an effect of inhibiting sympathetic influences to the heart and dampening the hypothalamic-pituitary-adrenal (HPA) axis. Our research results also showed that the masticatory organ activity, especially bruxism, has an attenuating effect to stress induced HPA axis and ANS activity. Therefore, it is suggesting that the masticatory organ has an important role in the social engagement system. From this kind of point of views, orthodontic treatment of occlusion for symptomatic patient is now more important than we thought before, especially the patient with displace the mandible. In this presentation, we will discuss about the important tasks of orthodontics in repositioning therapy of dysfunction patients.
