Need to raise the chin/extend the neck -Rotate the nose to the left
45
What corrections need to be made to this image of the open mouth odontoid?

46
What corrections need to be made to this image of the open mouth odontoid?
-Rotate the nose to the right -Lower the chin/flex the neck
47
What corrections need to be made to this image of the open mouth odontoid?
None-perfect image
48
What corrections need to be made to this image of the open mouth odontoid?
Lower the chin/flex the neck Rotate the nose to the left
