Which curve tends to have a mesial inclination as you move distally?

Which curve tends to have a mesial inclination as you move distally?

• A. Curve of Wilson
• B. Curve of Spee
• C. Monson's Sphere
• D. Lingualized Occlusion

Answer: (B)

The Curve of Spee is the anteroposterior curve of the occlusal surfaces seen in the sagittal plane. It is formed by the cusp tips from the tip of the lower canine through the buccal cusp tips of the posterior teeth. As you trace this curve from front to back, it tends to tilt toward the mesial direction when looking distally, giving a mesial inclination in the posterior region. This distinguishes it from Curve of Wilson, which is a transverse, mediolateral curve, Monson's Sphere, a 3D theoretical concept for overall occlusal curvature, and Lingualized Occlusion, which describes a contact pattern rather than a curvature.
