AIM: to evaluate three cephalometric measures: S-N.S-Ar, S-N and S-Ar, according to Jarabak's analysis. METHODS: using cephalometric teleradiographies in a lateral pattern in 12 dolichofacial individuals with skeletal Class III malocclusion, being six individuals of male gender and six of female gender, having a mean age of 27,2 years. The results have been compared to the intervals considered normal for each measure. For the statistical analysis, it was used the Student's "t" test, with a significance level set on 5%. RESULTS AND CONCLUSION: although the results would have not showed statistically significant differences, S-N.S-Ar and S-N have showed a trend of more low values than the interval considered normal.
