What are the main images used in treatment planning for orthognathic surgery cases?

  1. Lateral ceph

  2. Panoramic X-ray

  3. Dental casts

  4. CT scan

The correct answer is: Lateral ceph

Lateral ceph images are the main images used in treatment planning for orthognathic surgery because they provide a full view of the face, including the jaws and teeth. This allows for accurate measurement and analysis of the relationship between the upper and lower jaw. Panoramic X-rays may not provide enough detail for orthognathic surgery planning, while dental casts only show the teeth and not the jaw bones. CT scans may be used in certain cases, but they expose the patient to more radiation and are not always necessary for treatment planning.
