Following are the before and after x-rays from my experience with double jaw surgery. You can see, quite clearly, the drastic change that took place on the operating table.
I never realized how crooked my bite was before the braces worked their magic. You can also clearly see the open bite on the left side of my mouth, along with the 8 titanium plates screwed into my skull, in the last photo.
There you have it: a visual journey via X-rays! If you have any questions, feel free to post them in the comments.
