The purpose of dentofacial orthopedics is to modify the pattern of facial growth and the underlying bone structures of the face, such as that of patients with Moyers class III syndrome. The objective of this work is to present the dento-skeletal changes of a patient with Moyers class III syndrome treated with twin blocks. The case of a 9-year-old male patient who attended the orthodontic consultation of the University Clinic of Stomatological Specialties "Manuel Cedeño" in April 2019 is presented, his father worried about the aesthetics of the patient. By analyzing study models, cephalometric measurements and physical examination findings, the patient was classified as Moyers class III syndrome. Class III twin blocks were used as a functional maxillary orthopedic device. Dento-skeletal results were determined four months after the start of functional therapy. After the treatment, it was concluded that with the use of the class III twin blocks, the results were favorable because the dental occlusion relationship was corrected and a skeletal maxillo-mandibular class I was achieved.
