The following mandibular structural features were measured on lateral cephalograms at time 0 and time 1 (15\u2009months of treatment): the width and height of the mandibular symphysis and its width\/height ratio, the width and height of the mandibular ramus and its width\/height ratio, the antegonial notch depth and the Condilion\u2013Gonion\u2013Menton (Co\u2013Go\u2013Me) angle. Post\u2010treatment changes were assessed by Pancherz's cephalometric analysis, evaluating the increases in mandibular length.
