Vol. 15 – Number 60 – 2022 Case report Page 28-35 Treatment of class III malocclusion and bilateral posterior crossbite through orthodontic camouflage – case report Benedito Viana Freitas1 Izabel Cristina Vieira de Oliveira2 Felipe Luís Silva Borges3 Heloíza Viana Freitas de Melo4 Vandilson Pinheiro Rodrigues2 Pedro César Fernandes dos Santos5 Abstract Class III malocclusion is characterized by insufficient transverse size and crossbites are recurrent in patients with this skeletal pattern. 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.
