This article describes the complex case of an adult patient with skeletal Class II malocclusion and a hyperdivergent facial pattern, dental crowding and protrusion, and her extraction treatment with Invisalign clear aligners (Align Technology, San Jose, CA, USA). To achieve an optimal result, it was necessary to carry out accurate treatment planning using the ClinCheck software (Align Technology), following the principles of face-driven orthodontics. The patient, motivated by the invis-ible nature of the chosen appliance, displayed optimal compli-ance, which was essential to achieve all the planned treatment objectives. After 20 months of orthodontic treatment, the pa-tient was highly satisfied with the result, which reflected what had been planned in the beginning. It can therefore be said that Invisalign clear aligners, in addition to improving aesthetic outcomes, are a reliable and efficient appliance that is also suitable for complex orthodontic treatments.
