occlusal plane


Also found in: Dictionary, Thesaurus, Encyclopedia.

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

oc·clu·sal plane

, plane of occlusion (ŏ-klūzăl plān, ŏ-klūzhŭn)
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.
See also: curve of occlusion
2. In complete denture fabrication, surface of wax occlusion runs contoured to position teeth in denture.

Occlusal plane was traced by drawing a line passing through the intercuspation of upper and lower teeth.
After 20 adolescent patients taken orthodontic treatment, the change of distance from upper lip to esthetic plane had a positive correlation with posterior occlusal plane (r=0.365), distance from lower lip to esthetic plane was positively related to posterior occlusal plane (r=0.278), the plane was negatively correlated with nasolabial angle (r= 0.742), the upper lip tension had a positive correlation with the plane (r=0.419), distance from lower lip to H line was positively correlated (r=0.108), upper lip base thickness, chin soft tissue thickness and the plane had no correlation, Z angle was negatively correlated with the posterior occlusal plane (Table I).

Esthetics and function place a considerable demand on the design of the occlusal plane. Compromise can be achieved by altering the length of the radius of the curve.

Mesiodistal width of the lower third molar (MDW) was calculated, while the space/width ratio (SWR) was obtained through AER-7/MDW.The angulations of the lower third molar (Ang-8) were measured using the method of Venta.18 The angle between the occlusal line of the lower third molar and the occlusal plane was measured.
Clinically there is a disturbance in the occlusal plane such that the marginal ridges of the ankylosed infra-erupted tooth or teeth are apical to the occlusal plane.
To associate the pixel count of each imaged model with the true length measurements (mm), each model can be placed within a box of known size or the millimeter acetate paper can be placed between the camera and the occlusal plane of the dental cast [2].
