it might be good at this point to differentiate between the two term incisal ridge and incisal edge the incisal ridge is that portion of the crown which makes up the complete incisal portion. when and incisor is newly erupted , the incisal portion is rounded and merges with the mesioincisal and distoincisal angles and the labial and lingual surfaces. this ridge portion of the crown is called the incisal ridge. the term edge implies an angle formed bye the margin of two flat surfaces. therefore an incisal edge does not exist on an incisal until occlusal wear has created a flatten surface linguincisally, which surface forms an angle with a labial surface. the incisal edge is formed by the junction of the linguincisal surface, sometimes called the incisal surface, and the labial surface.

A face is the flat surface of an object (2 or 3 dimensional). An edge is when two sides (faces) meet on an object. A vertex is the corner of an object, where an angle exists between two or more lines.
The surface area of a cube with an edge length of 5 inches is 150 square inches.

A margain could be drawn on any edge of a paraghraph.

a ridge
The rock of the Mid-Atlantic Ridge is younger because it is formed through seafloor spreading where new crust is created at the ridge and moves away from it. In contrast, the rock found on the edge of continents is older because it has been at the surface for a longer time and has undergone various geological processes.

A knurl /nərl/ is a small projecting knob or ridge, especially in a series around the edge of something.
