Mount Vernon Index vs Yen Angle for Assessment of Anteroposterior Apical Jaw Base Relationship.

Aims And Objectives: This research aimed to determine the predictability and variability of the Yen angle and Mount Vernon Index (MVI) in relation to the other four sagittal discrepancy parameters, as well as to evaluate and explain any correlations that exist. The Lateral Cephalograms of 100 Class I Indian participants aged 17-24 years were recorded. The lateral cephalograms were traced for six distinct AP characteristics, including ANB, Wits appraisal, facial convexity, and beta angle, Yen angle, and MVI.
