First the eeeeek:
Now - look how they've moved:
& Back to the eeeeek:
Surprising to me is how much that lower right canine (on your left actually in the above pic) has rotated & laid back to be inline with it's lateral cuspid neighbour, along with the premolars. You can see how my arch has widened & become much more nicely rounded overall.
Here's my Clincheck still shots for this lower tray compared to the next (& last) tray in my initial plan. There are still small movements for my right front anterior to intrude a bit more, my right canine to upright & my 2nd premolar on the right side also, to straighten up. It's like every other tooth on that lower right side will have the most noticable movement. I'm sure some others will also be moving, but that's all that clearly shows on my Clincheck of the lowers. The uppers still need to widen a bit more on my right side as well.
All that crowding taken care of, along with the upper gaps after having only one IPR. It can be done.
Oh - & here's some food for thought: imagine doing away with all that goop that goes hand in hand (or hand in mouth rather) with taking impressions. An alternative device is a digital scanner that can painlessly take 3D data directly from a patient's mouth for input into a computer:

Goop/gagging may become a thing of the past sooner than not.
We are mere pioneers.
