The scientific article analyzes the results of a digital study of 3D-cephalometry, reformates of cone-beam computed tomography of the skull with reference points and measurements in the vertical, transversal and sagittal directions, reformats of plaster diagnostic models of jaw pairs of 115 respondents aged 7-11 years with occlusive pathology in mixed dentition period. The mesio-distal, vestibulo-oral and vertical dimensions of the crowns of temporary and permanent teeth were measured. The widths and lengths of the dental arches during the period of tooth replacement were determined using the Pont and Korkhaus method. The structure and frequency of occurrence of occlusal pathology in mixed dentition in the city of Stavropol was detailed. Anthropometric, odontometric and biometric methods for studying the parameters of the craniofacial complex during mixed dentition have been improved and personified.
