Vol. 12 – Número 47 – 2019 Relato de caso | Case report Página 126-134 Powerscope™ mandibular protraction appliance for treatment of craniocervical occlusal dysplasia (ccod) type II associated with mandibular deficiency, facial and dental arch asymmetry – a clinical case Lucas Lisboa Araújo1 Cristiany Alburquerque S. Gomes2 Marcelo de Moraes Curado3 Bruno Lima Minervino4 Marcelo Sousa Gomes5 Abstract In the last decades we can say that Orthodontics has undergone an unprecedented evolution. The discovery of new biological concepts, technological progress and the introduction of new techniques have been facilitating and accelerating the treatment of several malocclusions, among them Class II through mandibular retrusion. Several devices and techniques have emerged in recent times and the fixed functional appliances have had a considerable rise in interest. The present case report illustrates a corrective orthodontic treatment of a young patient with mandibular deficiency and asymmetry using the Powerscope™ device. This arises as an alternative for the treatment of craniocervical occlusal dysplasia (CCOD) – II with mandibular rebuilt in patients with permanent dentition and reluctant to orthodontic-surgical treatment. According to the appliance manufacturer, the device allows a greater range of movement, greater simplicity in the installation as well as more comfort and acceptance by the patient. The main complaint of the present case was the treatment of Class II malocclusion after failure of functional orthopedic treatment. The applied mechanics allowed the correction of the malocclusion, reaching satisfactory molars and canines occlusal relationships as well as aesthetics. It was possible to obtain an improvement in the patient profile and smile. The Powerscope™ device proved to be an excellent accessory for the treatment of the present clinical case having fulfilled its purpose and no intercurrences were reported during its use.
