The success or the failure of the orthodontic treatment accomplished in patients in the growth phase has been justiied many times by the standard and the variability that this growth can present. Understanding these current changes of the growth and separating them from the changes imposed by the orthodontic treatment is the objective of this work. The superimposition cefalometric method developed by Ricketts will be used and applied to a patient with skeletal malocclusion Class II, irst division, treated at the age of 9 years old and accompanied until the age of 18 years old. The mechanics used for the correction of the Class II was considered ideal since the obtained results were satisfactory, from the static point of view as well as the functional one. Besides, it was observed that a clockwise rotation of the jaw didn’t take place in spite of the use of a Quad - helix, Elastic of Class II and Cervical headgear. Another important discovery was the great growth of the jaw that occurred between the beginning (T1) and the end of the treatment (T2) of 12mm or 3,5mm/year.
