The angles to be analyzed were: the nasolabial angle, formed by the nose columnela and the nasolabial projection; the interincisal angle conformed by the upper and lower incisors; the mentolabial groove depth, that gave the length of depth between the lower lip and the chin; and the mandibular plane angle, which divide the sample, due to its degree of divergence with Frankfort's plane, into brachycephalic ([greater than or equal to] 25[degrees]), mesocephalic ([greater than or equal to] 30[degrees]) and dolichocephalic ([greater than or equal to] 35[degrees]) (Fig.
