Hi, Im new to invisalign, just having put in my 2nd tray last night.
Ive seen a lot of info on this and other boards, blogs, and the internet and general, but one thing I havent come across is how peoples Clinchecks compare to there teeth in real life.
Im curious both about the comparison of the finished product and of the steps along the way. Do you feel your teeth match up well to the clincheck? Has anyone whose finished taken pictures to compare the final result of each tray and assembled them into a clincheck-like movie?
The reason I ask is because I would expect that if the Invisalign were able to do exactly what it wanted, there would be no need for refinements. Am I wrong in this? Are people just deciding after a year of treatment they want something different than they did previously?
Clincheck vs Reality.

The clincheck model you see should match the aligners exactly, and your teeth should fit nicely in the aligners. It's not super exact, aligners dont fit 1 atom close to the teeth all the time, they can bend and flex and what appears on screen might not look the same as it appears in your mouth.
It's a good question tho and i too am interested in what someone who has finished the process has to say. I am currently half way through, and while i have not checked that my teeth match the CC exactly, i know they're not far off else the aligners wouldnt fit.

So the reason it came up was becuase when I extracted the frame by frame images of the clincheck, I could see that in one instance the tooth appeared to move, but actually, it just grew wider by the distance it was supposed to be moving. That made me think that there may be some problems in Invisaligns 3D rendering, but it turns out the free software I used just didnt do a great job.
I think the comment on the trays being flexible is valid, but (correct me if I'm wrong) the refinement trays are the same material and have the same limitations, so I would think that all refinements must be making new corrections, not fine tuning that are outside the limitations of invisalign.

Well my aligners certainly match the clincheck, but my teeth don't fit the aligners exactly. I am on tray 16 of 17 lowers and will probably need refinements because the small differences that have developed mean the result needs some further work.
- I've got a tooth that hasn't quite slid past the one next to it, becuase it rotated in a slightly downwards direction (or possibly didn't rotate upwards in the way the aligners planned)
As well as that, the end result could mean your teeth are exactly where they're supposed to be, but you still are not happy with the outcome.
- I have a sizeable gap at the base of a lateral incisor which has moved a long way. Clincheck showed that filled with gum, but of course my gum hasn't been able to recover from years of crowding and gum disease and fill the gap. I may need to move the tooth further than planned to achieve a good visual result.

Initial set: 31 upper / 17 lower
1st refinement: 14 upper / 10 lower
2nd refinement: 10 upper / 5 lower

Some of my teeth got a little off track with my initial 28 aligners. I could see how they didn't fit.
Also, my upper premolars were supposed to move outward (away from my tongue) more than they did. My refinements seem to be moving them farther out, the way they were supposed to move initially.
I don't think the aligners have enough strength to widen the arch well. I mean if all the teeth on one side need to move outward, then there are no other teeth to push back on (if you know what I mean). You can press the left molar and right molar parts of the aligners together without much resistance. So they basically have to overcompensate in the clincheck/aligners knowing that the molars won't move out as far as it shows on the clincheck.
But hopefully they get close enough initially, that with refinements they can get the teeth to where they should be.
