摘要：Studies carried out on the electro-myographic recording performed on the masticatory muscles and paravertebral showed that during a forced centric occlusion there is a difference in electrical activity of the muscle groups not only in localized but extended to the entire muscle chain of the spine. This shows how important it is to focus on the study of the postural position of the mandible and the way this position is able to affect the electrical activity and therefore the state of tonic contraction of certain muscle areas near and far from the apparatus tooth as the cervical paraspinal muscles and thoracolumbar. It appears, therefore, evident that the same mandibular postural changes may be responsible, or at least also favoring certain diseases of the spine.
