oc·clu·sal plane

, plane of occlusion
an imaginary surface that is related anatomically to the cranium and that theoretically touches the incisal edges of the incisors and the tips of the occluding surfaces of the posterior teeth; it is not a plane in the true sense of the word but represents the mean of the curvature of the surface.
See also: curve of occlusion.
Synonym(s): bite plane

occlusal plane

Etymology: L, occludere, to close up, planum, level ground
a plane passing through the occlusal or biting surfaces of the teeth. It represents the mean of the curvature of the occlusal surface. Also called biteplane. See also curve of Spee.

1. Plane established by incisal and occlusal surfaces of teeth. Because occlusal surfaces of teeth do not all lie on a flat surface, the plane is an "average" one.
