[The orthopedic effect of the Edgewise technic]

A statistical study of 30 cases treated in Edgewise technic shows the orthopedic effects of this technic upon adolescent patients who have a Class II, division 1 malocclusion. The Harvold's triangle and Mac Namara's analysis show the sagittal break of the maxillary growth, the significant acceleration of the horizontal growth of the mandible and the stabilization of the vertical growth of the face. The results are compared to the initial situation and to a prevision of growth without treatment.
