The mandibular protraction appliances do not depend on the patient’s compliance regarding the use of Class II elastics and correct the malocclusion in relatively shorter time, redirecting the mandible’s growth to a more favorable position. This study aimed to report the clinical case of a boy presenting Class II malocclusion and treated through Twin Force appliance associated with fixed orthodontic appliance. The result was a functional and satisfactory occlusion with the correction of the Class II malocclusion, dental midline shifting, overbite with passive lip sealing. The Twin Force appliance is of easy application, does not require a laboratorial step, and exerts constant force. The association with fixed orthodontic appliance resulted in the correction of the Class II malocclusion, as a viable alternative for the treatment of the Class II malocclusion, avoiding the extraction protocol and optimizing the treatment time length
