The Invisalign method is gaining an increasing interest as an alternative treatment option in adult patients and in difficult orthodontic cases. The aim of this work is to show a class II malocclusion with severe crowding in the upper and lower arches treated with the extraction of the upper first premolars performed by means of Invisalign. The alignment phase was successfully completed but the space closure achieved with crown tipping and without correct root inclination making a further fixed appliance phase necessary.
