Melo Toyofuku5 Abstract The aim of this research was to address the planning and treatment of a Class II/2 malocclusion treated without extractions, using orthodontic clear aligners. For this malocclusion treatment it is necessary to consider the severity degree, whether it is dental or skeletal (assess whether it affects only maxilla, mandible, or both), whether there is growth or not, patient collaboration, among other factors. Currently, many patients that search for orthodontic treatment seek more aesthetic appliances, mainly those who have already used the conventional fixed appliance. Thus, there was a great increase in the demand for removable clear aligners, since they provide benefits such as aesthetics, easier hygiene and shorter treatment time. In this case report, we tried to maintain good maxillomandibular relationship, the profile and good lip sealing. To do so, ClearCorrect® aligners were used, also it was chosen not to extract premolars and to perform a sequential distalization on the Class II malocclusion side, associated with Class II intermaxillary elastics, stripping (IPR) and atttachments. The results were highly satisfactory, restoring good molars and canines relationship, adequate upper and lower incisors buccolingual inclinations, overjet, overbite and middle line correction. Therefore, it was concluded that the treatment of this case with clear aligners was relatively quick, as efficient as the treatment with a conventional fixed appliance and met the patient’s aesthetic expectations.
