What is this view? What is this view used for.
How is this different from the occipitomental/waters view? What are you looking for in the occiptomental/waters view that you can't really see here? |
|
Definition
This is a posterior anterior view. It is mainly used for symmetry or lack thereof.
The occiptomental/waters view - the chin will be touching the receptor. You'll be seeing more of the sinuses in the occipitomental view. Here is a picture below.
