Trays 1 to 21 Comparison Shots

The changes between my very first set & #21 (which I'll finish a month from now)
This shows the difference between Set #21 compared to my first set below - even the shadows plainly note the changes in shape.




















Here's Set #21 on the left compared to my first set on the right.




















Interesting to lay Set #21 right on top of my first set.

You can see how much both my arches have widened -
the whole shape of especially my upper arch will have changed tremendously in the 9 1/2 months over which these trays take me.




My upper midline will end up shifted off center - slightly to the left, but remember I am missing a molar on that side from long, long ago. 
This is the view from below looking up with the respective sets together in occlusion:

Frontal together:

And here's the screenshot from my Clincheck of #19 where I am now.
You can compare that to the pics below - right on target.
