[MORPHOMETRIC CHARACTERISTICS OF THE ARTICULAR SURFACES OF THE TEMPOROMANDIBULAR JOINT IN DIFFERENT TYPES OF OCCLUSION IN ADULT PERSONS].

Using 200 skull specimens of adult persons, morphometric characteristics of the articular surfaces of the temporomandibular joint were studied in different types of physiological and pathological occlusion. For systematization of the skulls studied by occlusion type, the classification of V. N. Trezubov was applied. It was found that the sizes of the head of the mandible, the mandibular fossa and articular tubercle in orthognathic occlusion and transient forms were practically the same. Maximum differences in these parameters (sagittal head diameter, anteroposterior size and depth of the mandibular fossa) was found between the groups of skulls with orthognatic and abnormal types of occlusion. It is shown that in the anomalous types of occlusion not only the morphological characteristics of the articular surfaces of the temporomandibular joint were changed, but mostly the intra-articular topography of the articulating joint surfaces. These changes can serve as the major. causes of development of dysfunction of the temporomandibular joint.
