Prior-during function in propulsion movement

摘要

A cross-sectional, descriptive and observational study was conducted in 36 third year students of the Stomatology Faculty of La Habana, Cuba from January, 2006 to June, 2009. The aim of present study was to determine during the propulsion movement which were the functional dental function (prior function) established and prevailed in the population and which are those allowing a better funcioning of Stomatognatic System (SS). To analyze the occlusion the models of the dental arcades were related using a semiadjusted articulator type Dentatus. The 83.3 % of students had a prior function guided by the incisives. With decrease, the incisive-canine relationship the participation of the canines was greater to achieve the posterior non-occlusion with a potential influence in the type of prior funcion present in patient.
