Métodos:  Se realizó un estudio cuantitativo observacional, descriptivo y retrospectivo. Se tomó los modelos de estudio de pacientes atendidos con ortodoncia fija sin restricción de la edad. La muestra fue probabilística por conveniencia en total 15 modelos en cada grupo Clase I y II esqueletal. Se utilizó la prueba de rasgos de Wilcoxon con nivel de significancia al 95%.  Resultados:  Presentó cambios clínicos en las variables clase molar, longitud intercanina, longitud intermolar, forma de la arcada, análisis de mayoral. Cambios estadísticamente significativos en primer premolar y segundo premolar mandibular en Clase I.  Conclusión:  Se obtuvieron cambios estadísticamente significativos en Clase I, mientras que en Clase II solo presentaron cambios clínicos.]]></p></abstract>
