Table 2 Three occlusal planes

From: Twin study—genetic comparison of matrix versus intramatrix rotation in the mandible and three different occlusal planes

Bisected occlusal plane (Downs)

- Bisecting line through overlap of the distobuccal cusp of the first permanent molars and incisors overbite

Functional occlusal plane (Wits)

- The line bisecting the molars and premolars overlaps

MM bisector occlusal plane (Hall-Scott)

- The maxillary-mandibular planes angle bisector
