“…The values found in this study were for SNA = 84.3º, SNB = 81.3º, ANB = 3º, AO-BO = 4,1 mm (tables 2 and 3), quantities that relate the skull base with the maxilla and the occlusal plane with point A and point B, respectively. These values showed a greater protrusion of the maxilla and discrepancy between the bone bases in the anteroposterior direction [1,4].…”

“…The diagnosis and treatment plan of orthodontic patients of different ethnicities requires a differentiated cephalometric pattern, due to craniofacial characteristics related to the ethnicity that's being studied. Thus, the individualization of cephalometric norms for different races is extremely relevant [1].…”

“…Gn indicate the inclination of the lower incisor in relation to the mandibular plane, the values of 1-NA and 1-NB indicate the protrusion of the upper and lower incisors, respectively. In the present work, the values found were: for 1.NA = 24.3º; 1-NA = 7,5 mm; 1.NB = 31.7º; 1-NB = 7,9 mm; IMPA = 100.2º; 1.1 = 122.2º; 1.SN = 72.8º; 1.Go.Gn = 100.9º (tables 2 and 3), relating to studies[1,2,4,9].

Objective: The accomplishment of this cephalometric objective to evaluate the face characteristics of this cefalometric work individuals had to the city of this cephalometric prevalence, as well as measure the objective of malocclusion. Methods: For this study, 531 sort of individuals of the masculine organizations of Rio de Janeiro had been submitted to the clinical chait of the course of Master in Orthodontics of the Center Research Leopold Mandic, of which if it got prevalence of malocclusion. Results: Of this sample, it was observed that 22 individuals with normal occlusion and that if they had never submitted the orthodontic treatment. In these patients they had been made taken from normal head in lateral cephalometric radiographs and evaluated the cephalometrics largeness: SNA, SNB, ANB, Axle “Y”, NS.Go-Me, FMA, FMIA, IMPA, 1.NA, 1- NA, 1.NB, 1-NB, 1.1, 1.SN, 1.Go-Gn, SN.PLO, AO-BO, Line H, Z angle, P-NB, AFA, AFP and IAF. The gotten date had been submitted to the analysis with a level of significance of 5% (p< 0.05) and used descriptive statistics and the error of Dalbergh. The results showed that of the total of the evaluated sample, the malocclusion of 44.3% of Classroom I; 29.5% of Classroom II; 17.2% of Classroom III and 9.2% of normal occlusion. Conclusion: The individuals with normal occlusion of the city of Rio De Janeiro had presented equal cephalometric characteristics with many standard measures described in literature, except for the superior incisor that were presented vestibulate and the well inclined inferior incisor for vestibular contest.
