Allows maximum use of occlusal contacts
crest or ridge that extends from the apex of a cusp of a premolar or molar tooth toward the central part of the occlusal surface
a U- or W-shaped ridge at the base of the lingual surface of the crown of the upper incisors and cuspidteeth,
a pointed end where two curves meet, in particular.
. A small elevation of variable size on the crown of a tooth representing a thickened area of enamel or an accessory cusp.
ridge of teeth
any linear elevation on the surface of a tooth and is named according to its location
A rounded or angular depression in the occlusal surface of a posterior tooth bordered by the cusp ridges and the occlusal table.
The gingival sulcus is an area of potential space between a tooth and the surrounding gingival tissue and is lined by sulcular epithelium.

perikymata (Greek plural of perikyma)
are the pits around the long prisms of tooth enamel. They indicate the places where enamel-producing cells used to make contact with neighboring cells and are the result of normal enamel apposition.
An extension of the gingiva that normally fills the triangular space (i.e. gingival embrasure) between two adjacent teeth in contact just below (cervical to) the proximal contact area
A space between two adjacent teeth (not contacting) in the same dental arch
