The objective of this research was to determine the frequency of partial edentulism in the jaws of patients treated at the Department of Stomatology of the Central Military Hospital during the years 1999-2016. The frequency of partial edentulism was evaluated using the Kennedy classification and its modifications; data were collected using a form that recorded the present and absent dental pieces found in the clinical history. The sample consisted of 2,007 clinical records; the study was descriptive, observational, cross-sectional, and retrospective. Among the results, the highest frequency of partial edentulism was found in the strict Class III Kennedy classification in both the upper and lower jaws. In the upper jaw, males had a higher frequency of partial edentulism Class III strict Kennedy at 20.7%, and in the lower jaw, it was 15.7%. The age group of 40-49 years had the highest frequency of partial edentulism with strict Class III Kennedy in both jaws. The military occupation had partial edentulism with strict Class III Kennedy in the upper jaw at 18.1% and in the lower jaw at 12.2%. The study concluded that Class III Kennedy was the most frequent classification found in both jaws of patients treated at the Central Military Hospital.

El objetivo de la investigación fue evaluar la sensibilidad, especificidad y exactitud diagnóstica de los métodos UPenn y Yonsei utilizando tomografías computarizadas Cone Beam. Se analizaron 95 tomografías estandarizadas para medir las discrepancias entre los maxilares superior e inferior. Los resultados mostraron que la sensibilidad del método UPenn para detectar discrepancias transversales fue del 59.46%, mientras que la especificidad del método Yonsei alcanzó el 66.67%. En términos de exactitud diagnóstica, el método Yonsei presentó un valor de 61.05%. En conclusión, el análisis de Yonsei demostró ser más efectivo en la identificación de casos sin discrepancia transversal, lo que resalta su utilidad en el diagnóstico ortodóntico para mejorar la precisión en la evaluación de estas condiciones.
