Which of the following statements regarding ANB angle is false?
Correct Answer: Position of the sella influences this angle
Description: The ANB angle indicates the magnitude of the skeletal jaw discrepancy. The magnitude of the ANB angle, however, is influenced by two factors other than the anteroposterior difference in jaw position. One is the vertical height of the face. As the vertical distance between nasion and points A and B increases, the ANB angle will decrease. The second is that, if the anteroposterior position of nasion is abnormal, the size of the angle will be affected.
