Considering the importance of the frontal facial analysis in the diagnosis, the purpose of this research is to present a frontal facial analysis using standardized photographs, in rest position and during the smile, as an aid in the diagnosis and planning of the orthodontic and surgical treatment as well as in the evaluation of treatment results. The sample consisted of 40 white female subjects with a mean age of 22 years old, pleasant face, normal occlusion, and had not been previously submitted to orthodontic treatment nor plastic surgery. Colorful standardized 10x15 cm photographs were obtained with the patients in their natural head position. Two pictures were taken for each subject, one in maximum smile and another in rest position. Linear, angular and proportional measurements were used. Tests of normality, descriptive statistics, and error standard deviation were executed. The results showed that some of the measurements used in this study have values similar to that found in the literature and some are very different. All of the measurements were reliable after their repetition. And after this study, it is suggested a frontal facial analysis to be used regularly in the diagnosis and orthodontic treatment planning.
