• Angle class II malocclusion is a condition in which the upper teeth are positioned in front of the lower teeth, usually due to abnormal growth of the lower jaw in relation to the upper jaw, or due to a receding of the lower teeth. The use of Bionator is one of the many orthopedic devices that are used today for the correction of class II, division I, presents alterations in the jaw, teeth and muscles. This research aims to highlight the effectiveness of the bionator as a functional device widely used for the treatment of class II malocclusion, through the presentation of a clinical case. A minimal control experimental study was carried out to determine the possible morphological changes in a patient with Angle Class II division 1 with the use of the Bionator, in a period of 12 months. An observational, descriptive and retrospective study was carried out. The use of the Bionator proved to be a favorable alternative for the correction of the patient's overbite and profile. Success is directly related to the patient's collaboration, not requiring correction with fixed appliances in this case. There was an improvement in the patient's facial profile and a pleasant aesthetic smile at the end of the treatment. Based on this result, the use of functional orthopedic devices is recommended in the treatment of class II division 1 malocclusions based on an adequate diagnosis, correct selection of the orthopedic device and excellent patient collaboration.
