ABSTRACT Open bite is one of the most challenging malocclusions and its treatment must aim to improve occlusion and muscular function in the masticatory system, producing a satisfactory and stable result. This clinical report presents a patient with an open bite in mixed dentition associated with a Class II, division 1 malocclusion and a posterior unilateral crossbite. By combining functional and fixed appliances, the open bite was closed, a good occlusion was reinstated and muscular activity was improved in a simpler way. Therefore, this case report supports the idea of including myofunctional treatment when an open bite is treated at an early age.
