The registration of head position provides to examiner an important information that aids in the decision to treat dento facial deformities. The purposes of this study were: 1) compare three-dimensionally the reproducibility of the natural head position (NHP) and the oriented head position (OHP); 2) describe a new method to register the head position through face scanning and 3-dimensional analysis. Three facial records were performed in NHP and 3 in OHP, with a minimum interval of 1 week among the records (T1, T2 and T3). The angles of the 3 axes (X, Y and Z) were calculated and compared to evaluate the reproducibility of each head position. Ten subjetcs were selected to participate in this study, and a total of 60 records and 180 measurements were obtained for comparison of the most reproducible position. After aplying the paired t test for a normal sample, no statistical difference was found between NHP and OHP (p<0,05). Both methods proved to be effective in face positioning.
