This article reports the treatment of a 15-years-old female patient, with Class I malocclusion, severe upper anterior crowding, midline deviation to the left side and maxillary transverse deficiency associated with posterior crossbite. The procedures involved rapid maxillary expansion with modified Haas appliance and the use of Edgewise standard system. Proximal wear were performed to the alignment of mandibular incisors, as well as to reduce the Bolton discrepancy. This case was presented to the Brazilian Board of Orthodontics and Dentofacial Orthopedics (BBO), representative of category free, as partial fulfillment of the requirements for obtaining the title of BBO Diplomate.
