This paper consists of a case report of a Class II, Division 1 patient, 7.2 years old, in the mixed dentition phase, with exaggerated projection of maxillary incisors and mandibular retrognathism. The treatment performed was the use of the Klammt functional orthopedic appliance. After 24 months, the patient showed improvement in molar and canine relationship, reduction of overjet and overbite, and improvement in facial harmony. It is concluded that Klammt’s AOF proved to be efficient and effective in interception of Class II, Division 1 malocclusion of a growing patient, with skeletal, dental, and facial profile improvement and solving the patient’s main complaint of bullying.
