Are any of the following true?

  • ⁃ Your patient’s arch is edentulous
  • ⁃ The arch does have teeth, but insufficient AP spread, like the following examples:
    • ⁃ Just second molars
    • ⁃ Only 22 and 27
    • ⁃ 22 through 27, but in a very straight line

If any of these conditions exist, then your patient is insufficiently dentate and will need a marker-based protocol.


If your patient has 3 or more teeth, and they form a good triangular spread, then your patient is sufficiently dentate.
