Study Notes

Curve of Spee

Arrangement of the dental arches and inclinations of teeth are interrelated to optimize mastication forces and stabilize arches.
The Curve of Spee initiates at the tips of the canines and traces the buccal cusp tips of premolars and molars.
This curve is 2-dimensional and arches upward from anterior to posterior.
Molars on the Curve of Spee have crowns that tilt mesially while the roots tilt distally.
Premolars are positioned most upright or vertical in the dental arches.
Incisors are the teeth least perpendicular to the plane of occlusion.

Curve of Wilson

The Curve of Wilson represents a mediolateral curvature of the occlusal plane specifically for posterior teeth.
Its primary purpose is to complement the paths of the condyles during mandibular movements.
On the Curve of Wilson, mandibular molar crowns tilt lingually and their roots tilt buccally; maxillary molar crowns tilt buccally with roots inclined lingually.
The curvature deepens posteriorly, resulting in greater inclination of molars compared to premolars.
Due to this curvature, the buccal cusps of mandibular molars and lingual cusps of maxillary molars appear longer than they actually are.

Compensating Occlusal Curvature

The compensating occlusal curvature is referred to as the Curve of Monson.
The Curve of Monson is a 3D curvature; it is concave for the mandibular arch and convex for the maxillary arch.
