CEPHALOMETRIC ANALYSIS BASED ON CONE-BEAM COMPUTER TOMOGRAPHY (LITERATURE REVIEW)

Abstract

Conducting a cephalometric analysis is an integral component in the diagnosis of malocclusion. Inaccuracies in the identification of landmarks on two-dimensional images can lead to measurement errors. Threedimensional analysis based on cone-beam computed tomography expands diagnostic possibilities in clinical practice. In the electronic database of PubMed for the period from 2017 to September 1, 2023, an analysis of the scientific literature was carried out using the cephalometric analysis and cone-beam computed tomography, which describe the methods and statistically proven effectiveness of cone-beam computerbased cephalometry computer tomography. Among the selected 30 scientific works, articles were analyzed and systematized in the following areas: reliability of three-dimensional landmarks of dento-alveolar and skeletal structures on cone-beam computed tomography; effectiveness of cephalometric analysis based on cone-beam computed tomography in comparison with conventional two-dimensional x-ray cephalograms; comparison of cephalometric analysis based on cone-beam computed tomography and conducted using other additional research methods. Numerous studies confirm the high level of accuracy and reliability of cephalometric analysis based on cone-beam computed tomography, which expands the diagnostic possibilities in orthodontics and creates promising directions for further improvement. Conclusions: the reliability of measurements depends on the level of experience of the doctor (specialist), if adequate data for orthodontic analysis are obtained with the help of cone-beam computed tomography, additional cephalometric radiographs are not required. Prospective directions are the study of works based on reducing doses of ionizing radiation.
