The aim of this work is to present a clinical case treatment of Class III and bilateral posterior crossbite through orthodontic camouflage. Male patient, 18 years old and 7 months, reported as main complaint lack of occlusion between upper and lower teeth. He had Class III malocclusion, bilateral posterior crossbite, midline deviation, and facial asymmetry. Crossbite correction was performed using a sequence of expanded upper orthodontic arches and contracted lower arches and Class III camouflage by Multiloop Edgewise Archwire (MEAW) technique. At the end of treatment, it was obtained Class I occlusal relationship between canines, bilateral posterior crossbite correction and coincidence between the midlines. MEAW technique showed efficacy in Class III camouflage as well as the expanded and contracted arches sequence to correct bilateral posterior crossbite.
