AOBG was divided in two subgroups according to the treatment strategy: RME\/BB group (RME\/BBg) included 15 subjects (10 females, 5 males, QH\/C group (QH\/Cg) comprised 15 subjects (10 females, 5 males). The two subgroups were compared with a CG of 15 subjects (10 females, 5 males) matched for sex, age, vertical pattern, and observation period. Digital upper dental casts were collected before treatment (T1) and at the end of the active treatment (T2). Landmarks and semilandmarks were digitized on dental casts and GMM was applied.
