RESUMO
This case report describes the successful treatment of a 29-year-old young woman who had severe bimaxillary dento-alveolar protrusion, with the four premolars already extracted. Her face was convex, with a closed naso-labial angle, protruding and everted lower lip, associated with mentalis strain and a class I canine and molar relationships. After retraction of anterior teeth by using maximum anchorage mechanics through directional forces, facial changes were impressive, with a significant improvement of the dento-alveolar protrusion. Retraction of the incisors had corrected proquelia, reduced lips eversion and had improved the chin projection. As the lips were retracted, mentalis strain was reduced; this improved chin projection.
