Abstract　： [Introduction] Orthodontics is a very important discipline in contemporary dentistry. The ultimate responsibility of orthodontic professionals is to treat all of the components of the stomatognathic system to create an environment such that the dentition, the neuromuscular system, and the craniomandibular system can function synergistically. Orthodontists must expand their vision to include a comprehensive view of the functional relationship between the mandible and the skull and the dynamic relationships between the moving parts of the occlusion. Orthodontists should also have the means to identify tooth, joint, and neuromuscular pathology or pre-pathology for every patient in a clinical setting. The phrase "craniomandibular disorders" is synonymous with temporomandibular joint (TMJ) disorders, which are considered to be the main cause of pain in the extradental orofacial region (AACD, 1990). Sicher described the TMJ as a synovial gliding joint with a moveable socket. Under physiological ligamentary conditions in the inner capsular structure, translation takes place mainly in the upper articular compartment and rotation in the lower articular compartment. The articular disk, a moveable socket, is passively carried along during translatory lower jaw movement by ligamentary attachments. Under pathological conditions or with permanent or semi-permanent luxation (derangement), the condyle or a part of the condyle is not located in the proper anatomical relationship to the articular disk. Such problems comprise a series of morphofunctional alterations and abnormalities involving the temporomandibular articulation, the masticatory muscles, and the structures associated with these. There are multiple clinical signs and symptoms. Among the most frequent are : pain, usually located at the TMJ ; TMJ noise ; limitation of TMJ movement ; and headache.
