Abstract in Portuguese
Objetivo: Estudar e compreender aspectos topográficos e temporais do osso pré-maxilar e da sutura pré-maxilar - maxilar, por serem elementos anatômicos fundamentais pouquíssimos explorados clinicamente. Material e métodos: Foram avaliados 1138 crânios secos humanos, sendo que 116 (10,19%) dos espécimes eram crianças, e 1067 (89,81%) adultos. Os crânios foram fotografados e determinada a porcentagem de abertura da sutura pré-maxilar - maxilar. Posteriormente os dados foram tabulados e submetidos a análise estatística, adotando-se nível de significância de 5%. Resultados: A progressão de fechamento da sutura pré-maxila - maxilar foi de 3,72% ao ano. Em 100% dos crânios até 12 anos observou-se a sutura pré-maxilar - maxilar abertas na região palatina, enquanto 6,16% dos adultos. Conclusões: A pré-maxila existe de forma independente dentro do complexo maxilar e a presença da sutura pré-maxila - maxilar justifica o sucesso de expansões anteroposterior para o crescimento do terço médio da face e solução problemas anatômicos e funcionais

Abstract in English
Objective: To study and understand topographic and temporal aspects of premaxillary bone and premaxillary-maxillary suture, because they are fundamental anatomical elements that are rarely explored clinically. Material and methods: 1138 human dry skulls were evaluated, of which 116 (10,19%) of the specimens were children, and 1067 (89,81%) were adults. The skulls were photographed and the percentage of opening of the premaxillary - maxillary suture was determined. Subsequently the data were tabulated and submitted to statistical analysis, adopting a level of significance of 5%. Results: The progression of premaxillary suture closure was 3.72% per year. In 100% of the skulls up to 12 years the premaxillary suture was observed open in the palatal region, while 6.16% of adults. Conclusions: The premaxilla exists in an independ way within the maxillary complex and the presence of the premaxilla-maxillary suture justifies the success of anteroposterior expansions of the maxillary complex and solves anatomical and functional problems
