Teeth
The permanent dentition. The lower second premolar marks the column of the mental foramen; the upper incisal edge is where the lips meet at rest and the reference for lip support.
What it is
The permanent dentition. The lower second premolar marks the column of the mental foramen; the upper incisal edge is where the lips meet at rest and the reference for lip support.
How the Codex reads it
READ item A2 uses the profile of the lips against the incisors when reading a Class III upper lip; the mental foramen column is fixed from the premolars before pre-jowl and chin work.
Safety anatomy
The mental foramen most often lies below the second premolar, on average about twelve millimetres above the inferior border in men.

Every number in this atlas cites the study it came from. The full method, including what this site withholds on purpose, is on sources and method.
This site teaches one level above the Codex's working manual: the architecture is public, the coordinates are not. This page withholds entry points, landmark constructions, volumes and read-to-point routing, exactly as the atlas does. What is shown and what is withheld.
