| Popis: | Biometric studies of plaster models of the jaws and cone-beam computed tomography were carried out in 72 people of the first period of adulthood with a full set of permanent teeth and physiological varieties of occlusal relationships of dental arches. Patients, depending on the location of the incisors, are divided into three groups. The first group included patients with a mesotrusive incisor position and an inter-incisor angle of 130–140°. The second group consisted of people with physiological protrusion of the incisors and the parameters of the inter-incisal angle less than 130°. In patients of the third group, the value of the inter-incisal angle was more than 140ы°, and physiological retrusion of the incisors was noted. Analysis of the morphometric study of the anterior part of the dental arches showed the dependence of its shape and size on the vestibular-lingual inclination (torque) of the incisors. In people with the mesotrusive type of arches, the correspondence between the intercanine and premolar distances was determined. In people with protrusive type of arches, an increase in the distance between the canines was noted, compared to the distance between the premolars by more than 2 mm, and a decrease in the intercanine size by 2 mm is characteristic of people with the retrusive type of arches. The obtained data on the features of the parameters of the anterior part of the dental arches can be used as express diagnostics of the type of dental arches. |
