Virtual orthodontic setup in orthodontic camouflage planning for skeletal Class III malocclusion

The purpose of this paper was to emphasize the importance of the orthodontic setup in treatment planning for skeletal Class III malocclusion correction in an adult patient with moderate lower anterior crowding and anterior crossbite associated with two supernumerary lower incisors.

Keywords:
Orthodontics, corrective; Crossbite; Tooth, supernumerary; Incisor; Tooth extraction.
