Abstract

Class II malocclusion is characterized by a poor relationship such as dental arches, upper and lower, which may present dentoalveolar, skeletal origin or combination of both. The objective of the study is to evaluate cephalometrically the behavior of the maxilla and mandible observing as the anteroposterior and vertical changes of a patient with Class II skeletal that was treated with extrabucal cervical traction. The patient was followed for a period of one year in the case of a medical examination. The results were satisfactory, a decrease of the point convexity and an increase of the maxillary depth were obtained, allowing a restriction of the maxillary growth.
