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.
