Regressional Study of Cephalometric Measurements Involved in Establishing Skeletal Classes

This study proposes a regression model to identify the correlations between the values of cephalometric measurements for skeletal classes and the value of the ANB angle. Steiner analysis was performed on 120 lateral cephalometric radiographies. The statistical processing was made in SPSS 24.0. Depending on the skeletal classes (ANB angle), significant differences and linear correlation coefficients of the measurement values were identified (p<; 0.05). Standard multiple regression showed the combined influence of SNA (with the coefficient 1.000) and SNB (with the coefficient -1.000) angles values on ANB angle values. The study reveals the changes in the values of cephalometric measurements in case of skeletal discrepancies.
