Abstract
The aim of the work was to study the morphological state of the dentition of persons with normal occlusion according to cephalometric X-ray using extraoral parameters.A method for assessing the state of the maxillofacial system using the PoN reference line, PL line, PLV extrafacial vertical line is proposed. Schemes for determining the parameters formed on their basis are presented as well. These parameters will allow diagnosing disorders of maxillofacial system in patients with malocclusions at a higher quality level.The average values of the proposed new parameters were determined and presented in tables using extraoral parameters in persons 7–15 years old with normal occlusion. A comparative analysis of the angular and linear indices of cephalometric images in persons 7–12 and 12–15 years old with normal occlusion showed that with age the tendency of their change is identical to traditional methods.The proposed and studied angular and linear indices of cephalometric images in persons 7–15 years old with normal occlusion using extraoral parameters (PL line and PLV vertical line) are recommended for use in the practical work of orthodontists.
