Accurate assessment of sagittal skeletal relationships plays a pivotal role in orthodontic diagnosis and treatment planning. The ANB angle, introduced by Cecil C. Steiner, remains one of the most widely used parameters; however, it is influenced by cranial base length and jaw rotations. Similarly, the WITS appraisal proposed by Alexander Jacobson depends on the occlusal plane, limiting its reliability. To overcome these limitations, alternative angular parameters such as the Beta angle, Yen angle, and W angle have been introduced. While these parameters attempt to reduce dependency on cranial landmarks, variability in landmark identification and geometric construction persists.
