Hay que distinguir que los contactos de no-trabajo son aquellos que no causan disfunción o daño en los componentes del SE, y las interferencias, ya sea en lado de trabajo, no-trabajo o de hiperbalance, son aquellos contactos que causan una desviación del patrón normal de movimiento mandibular, causando cargas potencialmente nocivas para el SE(56). Concordamos con Davies (2001) quien enfatiza que antes de planficar un tratamiento se debe examinar el tipo de oclusión del paciente, su estado periodontal, ATMs, musculatura y relación con el componente craneocervical. Please enable it to take advantage of the complete set of features! Therapeutic occlusion Introduction For many years, in fact, for more than 100 years, dentists and researchers have debated how to identify and defi ne concepts of dental occlusion that could be applied in diag-nostic and therapeutic situations. Si se considera que cambios biomecánicos inducen una respuesta biológica en los distintos componentes del SE y por lo tanto en su respuesta adaptativa, se hace necesario plantear la búsqueda de objetivos que conduzcan a una buena práctica clínica en oclusión(1,7,12,22,24). The normal occlusion, based on the mesaticephalic skull, is as follows: the lower incisors rest on the cingulum of the upper incisors. Rinchuse y Kandasamy (2006), basados en estudios en Resonancia Magnética, indican que a pesar de realizar correctamente las técnicas de obtención de RC, en un gran porcentaje los cóndilos no se encuentran en la supuesta posición de RC(32).
