Concordancia en el diagnóstico de la clase esqueletal mediante los análisis cefalométricos de Steiner, Ricketts y Björk-Jarabak en radiografías cefálicas laterales de pacientes atendidos en la clínica odontológica “Barzallo Ortodoncia” en Cuenca-Ecuador, en el periodo de enero 2019 a diciembre 2024

Abstract

Cephalometric analysis is a fundamental diagnostic tool in Orthodontics, enabling accurate assessment of sagittal skeletal relationships. This study aimed to determine the diagnostic agreement among the Steiner, Ricketts, and Björk-Jarabak analyses based on lateral cephalometric radiographs from 400 patients (229 males and 171 females) aged 18–25, treated at “Barzallo Ortodoncia” clinic in Cuenca, Ecuador, between 2019 and 2024. Digital tracing was performed using NemoCeph software, and sensitivity, specificity, and concordance coefficients were applied for statistical analysis. Results showed high agreement between Steiner and Ricketts analyses, while Björk-Jarabak tended to overdiagnose class III due to high sensitivity but low specificity. It is concluded that the Steiner method is a reliable tool for confirming skeletal class diagnoses, particularly in clinical settings in Ecuador.
