RESUMO

The most published methods, for the anteroposterior jaw relationship appraisal, have got consideration. Some of them used cephalometric points in the anatomical structures far from the evaluated area (ANB angle), others as the Wits appraisal got instability and alteration of the occlusal plane and some others like MMº Bisector plane and ProjUSP evaluation used many cephalometric points and a complex cephalometric tracing technique. The aim of this paper is making easier the assessment of the anteroposterior jaw relationship by using the PmA plane with perpendicular drawing from just point B, with only a 3 point way, that may get possible a reliable anteroposterior jaw relationship assessment. The correlation among the PlanUSP appraisal and the ANB and FABA angles and the Wits and TPi appraisals was researched with a sample of 85 subjects (47 Class I and 38 Class II). The statistical analysis showed a significant correlation between the PlanUSP appraisal and the others measurements and evaluations researched, as if Class I or Class II subjects. Conclusion: The PlanUSP appraisal showed to be a method with a significant correlation and homogeneity with the ANB and FABA angles measurements and the Wits and TPi methods for the anteroposterior jaw relationship assessments.
