The mechanism for the dislocation of the temporomandibular joint (Dr Alireza Rouhi Shalmaei) Ukraine-Poltava)) A large number of clinical variants of pathological processes in the temporomandibular joint (arthritis, arthrosis, dysfunction, etc.) instability in the relationship of anatomical structures of the joint, leading to its functional disorders, is one of the few developed dental problems. The structure of the TMJ requires to consider it as kinematically active, multifunctional, adaptive biological microsystem-related musculo-ligamentous and occlusive component of the masticatory apparatus. Particularly important in the development of instability in the TMJ, manifestation of which may be a dislocated joint, is the spatial arrangement of its internal structures in relation to each other in all three planes. ted topic. A norm accepted location of the articular disk above the head mandible and the overlap of the articular surface of the head, the articular fossa and articular tubercle in the longitudinal and transverse planes. Based on literature data and results of clinical examination and treatment patients with dislocations of the mandible, it seems that most of these patients have an anatomical instability elements of temporomandibular joint (articular head, intra-articular disc ligamentous apparatus). It is well known that an important component of an adequate function of the TMJ on the background of the permanent load is a system of maintaining optimal symmetric mechanisms and biomechanical status autoregulatory stabilize the joints, which cause dynamic anatomo-functional position of the lower jaw, lower jaw stability in its movements. Anatomical instability temporomandibular joint (TMJ) should be regarded as either a reactive or a pathological state, which has a distinctive clinical manifestations, reflecting the characteristic shifts: violation base function of the joint surfaces – unintentional violation of the motor function of one or both joints of uncontrolled displacement of the lower jaw) – the appearance of unusual movements of the articular head lower jaw by discoordination of masticatory muscles and inadequate displacement of contacting surfaces of the joint – the emergence of serious intra-noise (crackle, crackle, etc) – the development of pain, and likewise kind of symptoms we observed 23 patients appeared after a visit to dentists in different fields.
