Geometrical Shapes of Crowns

Understanding the basic geometric shapes of the crowns of teeth provides an overview to the more detailed anatomical features of individual teeth. Locations and extent of crests of curvature (contour) of crowns, positions of cusps and incisal ridges will be better appreciated once the geometric shapes of the crowns in each view are understood.

All of the crown surfaces (except for the incisal and occlusal views) can be described using one of three basic geometrical shapes. They are triangular, trapezoidal and rhomboidal.

The shapes of crowns from the incisal (anterior teeth) and occlusal (posterior teeth) views will be addressed in the detailed chapters on each individual tooth in the primary and secondary dentitions.
