angles. By contrast, a line angle is formed by the junction of two surfaces and
derives its name from the combination of the two surfaces that join. For instance, on
an anterior tooth, the junction of the mesial and labial surfaces is called the
mesiolabial line angle. Each tooth has 8 line angles. The occlusal surface is toward
the opposite arch on a posterior tooth whereas the incisal surface is the surface of
an incisor that is toward the opposite arch.
