Comparative evaluation of methods fordetermining the width of the upper jaw in growing patients

Aim. To conduct a comparative evaluation of methods for measuring the width of the upper jaw in growing patients in order to determine the difference between these standard values and improve diagnostics. Materials and methods. The study was conducted in 20 patients aged 6, 8, 10 and 12 years. Measurement of the transversal dimensions of the jaws was carried out on frontal cephalograms using the Ricketts cephalometric analysis, and on CBCT scans using the analysis of the University of Pennsylvania. Results. The results of measurements by frontal cephalograms and CBCT scans have almost the same indicators, the data of both methods differ insignificantly. Conclusions. As a result of the study, both methods confirmed their reliability, however, the analysis of cone-beam computed tomography has a number of advantages. Accordingly, it is possible to simplify the carrying out of diagnostic measures to determine the width of the upper jaw, limiting ourselves to one research method – cone-beam computed tomography without prescribing additional teleroentgenography.
