The aesthetic treatment of dentoalveolar biprotrusion is one of the greatest challenges for the orthodontist. The present article aims to show an approach in an adult patient with Class I malocclusion associated with a biprotrusion who did not wish to have the aesthetics of her smile compromised during orthodontic treatment. The treatment plan consisted of installing a lingual orthodontic appliance to distalize the upper and lower teeth through absolute anchorage. At the end of the treatment, the malocclusion was corrected efficiently, aesthetically and quickly.
