Resultados de la corrección de la Clase II con un bionator modificado

we analyzed patients with retruded mandible and class ii malocclusion, treated with a bionator appliance in a first orthodontic phase. the patients were included in the study if they had stable normocclusion more than four years after completion of the whole treatment. results show favourable, but light, changes in sagittal relations of both jaws, and significant changes in the proclination of both incisors, that helped to correct class ii malocclusion.
