THE INFLUENCE OF DENTOFACIAL ANOMALIES

THE TEMPORO-MANDIBULAR JOINT

 

 Temporomandibular joint (TMJ) is one of the most active of human joints. The complexity of the anatomical structure and biomechanics accounts for the high frequency of its dysfunction. Diseases of the TMJ can act as a launcher and supporting factors in the development of systemic pathology.  Dental anomalies can cause pathological changes in the TMJ [1,3,4,8].  From 78.3% to 95.3% of patients with disorders of occlusion have some form of TMJ dysfunction [2]

Basic research aimed at identifying abnormalities in the TMJ: occlusivity, x-ray and graphic methods of research (orthopantomography (OPG)), teleradiography of the head (TRH) in the lateral projection, and computed tomography (CT) of the temporomandibular joint or TMJ sonography), axiography, electromyography, revatropate, monoarthritis, articulators and their use for the diagnosis and remediation of occlusion, EMG of the masticatory muscles from both sides, MRI (to determine the relationship of the anatomical elements of the temporomandibular joint [3].

Additional methods of research of a condition of TMJ tissues (CT, MRI) in patients with clinical manifestations of dysfunction recommended after evaluation of the extent to 16 morphological changes of the articular structures on the basis of imaging and the predictive formula. The treatment of such patients should be carried out taking into account the severity or risk of development of morphological changes in the TMJ structures. Beam diagnostics TMJ must include x-ray (TMG, CT) and norethandrolone (ultrasound, MRI) research methods [3,7].

The most characteristic clinical manifestations of the disease are: pain and sound phenomena in the field of TMJ contractures (inflammatory and non-inflammatory Genesis). [4,6].

 At the time of diagnosis in the joint clinic the number of measurements and sampling records all the sensations in the joints (discomfort, clicking, pain, deviation of the jaw when opening and closing), the difference in sensation in the right and left joint. Often orthodontist, in addition to the manual functional analysis, conducts a visual assessment: posture, symmetry of shoulder girdle, shoulder blades, hip bone structures, etc., performs the necessary samples, photos. According to the results of possible appointment for a consultation with an osteopath or chiropractor for joint patient management. The treatment plan also can be connected related professionals (orthopedic surgeon, periodontist)[1, 5].

More than 67% of patients with disorders of the teeth occlusion and dentition have different pathology, TMJ, and more than 78% of patients with disorders of the TMJ are various disorders of the teeth occlusion and teeth row, which confirms the fact that the pathology of the TMJ in the majority of patients is associated with impaired occlusion. Occlusal and muscular factors are interrelated: the discoordination of the functions of the masticatory muscles increases joint pathology, and arose in the joint amendments strengthen the dysfunction of the muscles. Changes in the masticatory apparatus will introduce to dysfunction of the masticatory muscles and impaired functions of both the articular joints. Long-existing increased load on the TMJ tissue leads to disruption of blood flow in cartilage, cartilage loses elasticity, its surface cracks occur, gradually progressing degeneration of cartilage. Further pathological process goes to the bone structure of the joint, which leads to various deformations of the lower jaw head. At the same time the pathology of the TMJ not associated with the occlusion, the progression of the disease, leads to disruption of the synchrony of movement articular heads, and their offset and formation of pathological bite. Thus, a vicious circle: occlusion lead to pathology of the TMJ, which in turn leads to a change in head position of the mandible and malocclusion.
