Orthodontic compensation of Class III malocclusion with mini-implants used as skeletal anchorage in orthodontic mechanics has been revolutionizing the Class III skeletal treatment. Orthodontic camouflage with compensating corrective orthodontic treatment was chosen, using a fixed appliance in the Straight Wire technique (Capelozza III) and distalization and verticalization mechanics of mandibular premolars with a 19×25 upper steel wire and 20 lower steel wire through the Buccal Shelf, a mini steel implant inserted in the retromolar region between the first and second mandibular molars. Crowding was satisfactorily corrected with effective arches alignment and leveling. Vertically, a considerable change was observed, as there was correction of the anterior open bite by extrusion of the incisors creating an adequate overbite and overjet. The use of extra-radicular mini-implants adapted in the root Buccal Shelf region as an anchorage resource proved to be effective in the patient Class III vertical skeletal compensatory treatment.
