What anatomical landmark is identified as the most inferior point of the mandibular symphysis?

The most inferior point of the mandibular symphysis is referred to as the Menton (Me). This anatomical landmark is specifically situated at the lowest point of the symphysis of the mandible, serving as a crucial reference in cephalometric analysis and orthodontic evaluation. The Menton is used in various measurements and analyses as it provides a consistent point of reference for the overall height and morphology of the mandible.

In contrast, other landmarks such as Gnathion (Gn), which represents the lowest point on the contour of the mandible, is located slightly more posteriorly and laterally compared to the Menton. The Pogonion (Pog), a forward projection of the mandible, serves as a reference for the chin's prominence but is not the lowest point of the symphysis. Infradentale (Id), on the other hand, is located just above the lower incisor's alveolar margin, making it further from the inferior boundary of the symphysis.

Thus, the definition of these anatomical landmarks highlights why the Menton is specifically characterized as the most inferior point of the mandibular symphysis.
