Mandibular Angle Point

*Mandibular angular point* (n. angularis mandibulae) is an anatomical point on the human lower jaw, located at the lower edge of the chin. It is one of the important landmarks for determining many facial forms and disorders in the dental system.

The mandibular angular point is located on the edge of the upper lip, anterior to the canine and just above the sternocleidomastoid muscle. Approximately at this place there are other anatomical points, such as the corner of the mouth (angulus oris) and the edge of the lips (praecordium labii). When viewing the face in profile, these three planes form a triangle, the apex of which is at the intersection of the midline of the lower jaw and an imaginary line passing vertically through the lower edge of the chin (see Fig. A).

There are many points and lines in human anatomy that can be very important to understand and use for medical and surgical purposes. One such point is the mandibular angular point, also known as the gonion point. In this article we will look at the features of this point and its significance in human life.
