Final answer:
The coronoid process of the mandible should be superimposed on an AP odontoid view.
Step-by-step explanation:
When superimposing an AP (anteroposterior) view of the odontoid process, the coronoid process of the mandible should be included. The coronoid process is a flattened upward projection from the anterior margin of the mandibular ramus. It serves as an important landmark for the mandible.
