Temporomandibular joint (TMJ) and cervical spine: is there any relationship between them?

Abstract

Many studies supported the clinical, anatomical and functional relationship between the cranial region, the temporomandibular joint (TMJ) and the cervical spine; however, the mechanism of this relationship remains unclear, and the relation between temporomandibular disorders (TMDs) and the head and neck posture changes are still controversial. The understanding of the complex interrelations between the stomatognathic system, cervical spine, pain and dysfunctions in other areas of the body is useful in order to be able to treat patients more efficiently and effectively at the initial stage, when painful symptoms appear, and to cure them much swifter and in a more efficient way. On the other hand, the increased severity of temporomandibular disorders also could lead to a compensatory or antalgic posture of the neck. The function of the masticatory system should be evaluated in patients with neck complaints to rule out the possible involvement of the masticatory system. In addition, to be able to make successful therapeutic interventions, dental surgeons should cooperate in an interdisciplinary fashion with neurologists, orthopedists or neurosurgeons.
