Study Notes
Occlusal Surface
- The occlusal half of the surface is convex, but has a buccolingual flattening or slight concavity cervical to the contact area.
Mesial Surface
- The mesial surface exhibits a roughly trapezoidal shape that is wider at the cervical than at the occlusal.
- The surface is wider at the cervical than at the occlusal due to the general convergence of both the buccal and lingual surfaces toward the occlusal.
