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.
在头影测量学中，ASBS/咬合角和“Wits”评估可精确确定上下颌之间的矢状差异。主要介绍了标准化定位点A、B和Mo的程序，以便在不产生任何变形的情况下反映解剖学情况。证明了再现上述头影测量点、线、角和距离的准确性，并展示了在理想情况以及II类1分类、II类2分类和III类错牙合畸形中ASBS/咬合角、“Wits”评估和ANB角的表现。建议使用ASBS/咬合角或“Wits”评估作为头影测量矢状颌关系的方法，并根据所述标准化程序定位点AS、BS和Mo。
