Thanks for posting the pictures. I am interested in the same appliance for my wife once her braces come off (sometime next year), so it was great to see what it looks like especially with the facebow. Do you find that's comfortable to wear?
I had to make some adjustments, to make it comfortable, meaning a Dremel tool and some high grade sand paper.
The bite was a bit off so both upper and lower brace would not be flat if I bite down. And my mouth would be open a lot...
The angle between them i had to adjust.
Now its very comfortable. I can close my lips and i sleep with the twinbock and headgear on as well. No problem.
Its nice that you can adjust how tight you want to have the fit, with the expanders.
Just make sure your impressions are good, then you will be fine.
Let me know if you need any more info etc... Im glad to help out.
Br,
