Most patients with skeletal Class II malocclusion present a retruded position of the mandible. Functional appliances are fixed or removable appliances designed to alter the sagittal and vertical mandibular position, resulting in orthodontic and orthopedic skele- tal changes. Despite their long history, functional appliances remain controversial in their use, effectiveness and mode of action. This review will reveal the different treatment options for skeletal Class II malocclusion caused by mandibular retrusion, such as: Bionator, Twin block, Herbst, Jasper jumper, Forsus, mara and Advansync; it will also explain the mode of action, skeletal and dental effects and optimum treatment time for stability.
