Landmarks
- Occlusal plane: Formed by bisecting overlapping cusp of first premolars and fist molars.
- AO point: It is gained when a perpendicular is drawn from point A to occlusal plane.
- BO point: It is gained when a perpendicular is drawn from point B to occlusal plane.

Interpretation
- In normal occlusion:
- In men: BO is ahead of AO by 1 mm.
- In women: Both AO and BO coincide in women.
- In Class 2 malocclusion: AO is ahead of BO.
- In Class 3 malocclusion: BO is ahead of AO.

Drawbacks
- In the appraisal readings obtained are solely dependent over occlusal plane inclination.
- When the clockwise rotation of occlusal plane is carried out AO lies behind BO but when counterclockwise rotation of occlusal plane is carried out BO lies behind AO.
- So for making out the anteroposterior relationship the Wits appraisal is combined with other method.
