Chin generally refers to the lowest part of the maxillofacial region, commonly known as chin.

The chin is located at the lower edge of the mandible and is connected by horizontal branches of both mandibles. Its lower edge and the upper edge of the neck form a mental neck angle, which is the dividing line between the maxillofacial region and the neck.

The chin is the lowest part of the face, which forms the whole face together with the cheeks, nose, lips and other organs, and forms the basic skeleton outline of the face together with the zygomatic arch and mandibular angle on both sides, and its shape determines the face shape.

The position and shape of the chin have a great influence on the face shape, and its development determines whether the face shape is beautiful or not. If the chin is underdeveloped, it may form a pointed face or a bird-shaped face. On the other hand, if the chin is overdeveloped, it may form a long face or a horse face, which will also affect the beauty of the maxillofacial region.
