[The AS/BS occlusal angle, a replacement for the ANB angle].

In cephalometrics the ASBS/Occlusal angle and the "Wits" appraisal determine the sagittal discrepancy between the upper and lower jaw precisely. Standardizing procedures in locating points A, B and Mo are primarily introduced in order to reflect the anatomical situation without any distortion. The accuracy in reproducing the said cephalometric points, lines, angles and distances is proved and the behaviour of the ASBS/Occlusal angle, the "Wits" appraisal and the angle ANB is shown in ideal cases and in class II/1, II/2 And III malocclusions. It is recommended to use either the ASBS/Occlusal angle or the "Wits" appraisal as a cephalometric measurement of sagittal jaw relationship and to locate points AS, BS and Mo according to the standardizing procedures described.
