Analyse of the nasiolabial angle

Abstract

We analyzed the nasolabial angle and different factors that influence it in patients of 9.0 ± 1.4 years of age. An average value of 115.30 ± 10.8 was obtained. The inclination and the position of the upper incisive and the ANB angle constituted the osseous and dental factors with greatest repercussion on the nasolabial angle. Sex and age did not condition significant differences. The labial incompetence determined a more acute angle.
