Found this a while ago. Sadly I have no idea what's the story behind it and what it is based on. At face value, it does seem accurate enough considering the nature of the subtle changes I have seen in myself and others. What do you think?
That's very interesting! Is the cranium itself changing shape?

This is great. You can see the reduced midface ratio as everything swings up. This is consistent with my experience
Welcome back.
Interesting animation, but I do not think it's entirely accurate. First, the maxilla does not appear to be achieving a full CCW rotation. The back teeth and bone do not appear to be swinging down while the face rotates. Second, the maxilla seems to have developed a skeletal protrusion in process of rotation.
On the other hand the it does show clear forward facial movement. The SNA angle moved from 80° to 86°.

Bones are super maliable. This is the case for kids at least. Dr. John Mew's whole premise. Dr. Mike Mew takes a treacherous step forward into treating adults. We will soon have REAL resolutions to this stuff. What I mean by that is results that are not highly inaccurate.

Thanks Abdul. A couple of questions: what do you view as a "full CCW rotation" and what should be the centre of rotation in relation which the rotation was to be quantified? What area are you comparing the teeth to when you say that they are not moving down? If the whole skull is moving, then whether a particular area is moving up and down would depend on where the 'anchor point' is viewed to be. Consider for example if the base of the skull is anchored in place:
Now suddenly it would appear as if the molars were swinging down.
This looks more like the results of AGGA especially in Ron's case.
My own results have been similar in terms of how the midface has shortened and how the maxilla seemingly seems longer from front to back. The occipital bone lifting upwards also seems consistent with fixing forward head posture. My occiput is very much "lifted" away from my neck the same way my midface seems to be lifted away from my neck just the same.
What I find different is the fact my molars seem lower compared to my canines and incisors now. Last night during teeth brushing I felt I was going down as I brushed backwards. Very new sensation considering I always felt like it was going up. Placebo? Mainly though I feel as if my side gums becoming more exposed and my top gums less exposed makes me feel like my occlusal plane has shifted in a counterclockwise direction.

A full rotation to the occlusion plane would look like this in an advance le fort 1 surgery:
The surgeon would cut at the base of the nose a straight line, push the back of the upper jaw down, and then move the whole piece forward. Later in braces the teeth would be arranged in a curve of spee layout.
The animation seems to show only forward movement. If you compare the back of the upper jaw to the skull base as you suggest it seems both are moving up at the same rate, so there is no change.

I wonder if you agree that surgically cutting the bone in two at a spot where the bone normally is one solid block, can in no way be used as an explanation to how the bone should naturally develop? Besides, you did not explain what makes this operation a 'full' CCW rotation instead of just CCW rotation?
>The animation seems to show only forward movement
I see something different. Does this help you?

The point is to show how CCW rotation effects the occlusion plane. Compare the occlusion plane in the animation final outcome to the one in this illustration. Notice how it's more straight or horizontal than the one in the animation. The one in the animation continues to tilt down at the same steep rate. That can never be normal in a full CCW rotation.

Yes I am aware of this change in height and I do not think it's realistic to the extent it's shown here, but my comment was specific to the section of the teeth. It dose not shrink in height, it just mainly moves forward.

Ah, I get your point - I would expect the occlusional plane get more horizontal too.

Sorry to hijack this thread, but what do you think about doing this: https://youtu.be/BBt06kjJD_s?t=192
But using a removeable palate expander, instead of a fixed one? My upper incisors are also fixed with a permanent retainer which makes sure i dont mess them up.
The treatment with the facemask is used by orthodontics. What would speak against just doing it myself with a brace like this one https://www.bracesshop.net/dehnplatten/1/y-platte-oberkiefer?number=0004.2 and having the ruber bands attach to the back molars/wire.
This guy : http://jawpain-tmjtreatment.com has done the same thing, and actually recommends a removeable palate expander if you dont have braces anymore.
Sorry if this idea was discussed here already. The forum doesnt even have a search function
