What point is defined as the most anterior point on the contour of the bony chin?

The most anterior point on the contour of the bony chin is known as the pogonion, commonly abbreviated as Pog. This anatomical landmark is significant in cephalometric analysis as it is crucial for studying the projection of the chin in relation to the rest of the facial structure.

The pogonion serves as a reference point for various measurements, including assessing facial profile aesthetics and orthodontic treatment planning. Its position can indicate the degree of facial convexity or concavity.

The infradentale, or Id, is located at the lowest point of the alveolar process of the mandible where the teeth are present, making it a different reference point that is not located on the contour of the bony chin.

Menton, or Me, refers to the lowest point of the symphysis of the mandible, marking the vertical height of the chin rather than its anterior projection.

Supramentale is defined as the point located at the most anterior part of the alveolar process, just above the mental region but still does not represent the most prominent anterior projection of the mandible like the pogonion does.

Thus, the pogonion accurately describes the specific anatomical point being asked about in this question.
