Correct answer: EThe anteroposterior curvature from the canine tip through the buccal cusp tips of premolars and molars to the most posterior molar

The curve of Spee is the anteroposterior curvature of the occlusal surfaces when viewed from the sagittal plane. It extends from the canine tip through the buccal cusp tips of the premolars and molars to the anterior border of the mandibular ramus. A deep curve of Spee is associated with deep overbite. The curve of Wilson is the mediolateral (transverse) curvature caused by lingual tilting of mandibular posterior teeth. Together they form the sphere of Monson.
