Resumo

O ângulo ANB pode expressar, além da relação entre as bases apicais. um índice de prognatismo facial, considerado, também, uma característica étnica. Neste estudo, verificou-se a média de amplitude deste ângulo numa amostra de jovens brasileiros com oclusão aceitável e os resultados foram comparados com os de outras populações, incluindo povos primitivos e pré-históricos. A média obtida revelou nào ser estatisticamente diferente dos padrões ortodônticos de normalidade e evidenciando perfis faciais equilibrados. Entretanto, num panorama geral. os resultados nas várias populações, mostraram-se extremamente diversificados, não ocorrendo nenhuma forma de ordenação, a não ser a decorrente dos diferentes grupos etários.

Abstract

Besides the relationship between the apical bases the ANB angle may express an index of the facial prognothism, which is also considered an ethnic characteristic. In this study the average of the ANB angle amplitude was verified in a sample of Brazilian youths with good occlusions and the results were compared to those from other populations, including primitive and pre-historic people. The average showed to be wever, the data obtained in several populations were extremely diversified, with no ordering other the age groups

Keywords
