This article reports on the orthodontic treatment performed on a 36-year-old female patient with skeletal and dental Class III pattern, presenting with a left unilateral posterior crossbite and mandibular asymmetry, and a relatively significant difference between maximum intercuspation (MIC) and centric relation (CR). The treatment was performed with maxillary dental expansion, mandibular dental contraction and anterior crossbite correction, eliminating the difference between MIC and CR. Results were based on careful diagnosis and planning of orthodontic compensation without surgical intervention in the maxilla, at the request of the patient. This case was presented to the Brazilian Board of Orthodontics and Facial Orthopedics (BBO) as representative of Category 5, i.e., malocclusion with a transverse problem, presenting with a crossbite in at least one of the quadrants, as part of the requirements for obtaining the BBO Certificate.
