Resumen
Objetivo: determinar los patrones de articulación de fones consonánticos en sujetos de habla española chilena clases I, II y III esqueletal; comparar las diferencias fonéticas que existan entre clases esqueletales.
Métodos: se seleccionaron 54 individuos que cumplían con los criterios de inclusión determinados mediante un examen clínico intraoral y a través del análisis de Ricketts, y se conformaron los grupos de estudio de pacientes clases esqueletales I, II y III. Se les realizó un examen fonoarticulatorio estandarizado para determinar los fones modificados y el patrón articulatorio compensatorio realizado.
Resultados: se observaron cambios en el punto de articulación de fones consonánticos en las tres clases esqueletales, con diferencias significativas en los grupos de fones anteriores y medios entre pacientes clases I y II, sólo en el grupo de los fones anteriores entre pacientes I y III. Entre pacientes clases II y III no se observaron diferencias significativas. Se reportan modificaciones y compensaciones cualitativamente distintas entre las clases esqueletales.
Conclusiones: en relación a pacientes clase I, los pacientes clase II o III, presentan distinto grado de modificación en el punto de articulación de fones consonánticos. Las diferencias observadas se relacionan con los patrones esqueletales propios de cada clase.

Abstract
Purpose: to determine the consonant phonemes articulation patterns in Chilean skeletal class I, II and III Spanish speakers and compare their phonetic differences.
Methods: fifty-four skeletal class I, II and III subjects were selected, based on intraoral clinical examination and Ricketts cephalometric analysis, constituting the study groups. A standardized phonoatriculatory test was applied to each patient to determine the modified phonemes and their compensatory patterns.
Results: the findings indicate changes in articulation in all three groups. Significant differences were found in anterior and medium phonemes between skeletal class I and II and only in the anterior phonemes between skeletal class I and III. There were no significant differences between II and III skeletal groups. Qualitatively different modifications and compensations between skeletal classes are reported.
Conclusion: different degree of modification in consonant phonemes articulation is shown in class II and III patients when compared to class I skeletal subjects. These differences are related to the skeletal patterns.
