Objective The purpose of this study was to perform a cephalometric evaluation of the mandibular incisor position and its correlation with Class I, II and III malocclusions in individuals with a brachyfacial pattern. Methods The sample consisted of 60 lateral teleradiographs of the head, with images of good quality and clarity from the documentation of adult patients of both genders, with complete permanent dentition, who had not previously been submitted to orthodontic treatment. Results The measurements for analyzing the mandibular incisors were obtained by means of the variables that characterize the mandibular incisor position, namely: 1.NB, FMIA, IMPA, DC (Tweed’s Cephalometric Discrepancy). The data were submitted to statistical analysis using the Kruskal-Wallis test p<0,05 and Spearman’s correlation test considering each measurement as a function of the malocclusions. Conclusion It was concluded that there is direct correlation of skeletal discrepancies with the lower incisors positioning in individuals brachyfacial, and therefore the greater the Class II greater the tendency for flaring of the lower incisor, and the higher the class III greater the tendency for these teeth lingually
