I asked CrystalBraces if they use elastics, and they do not. So, I don't think I will use them. I'd have to rig my own elastics or headgear, and in that case I could use a DIY "invisible" retainer instead which would be cheaper.
I'm contemplating 3 options for my particular problem:
#2 is going to be expensive.
#3 may be risky.
I plan to schedule some consultations with orthos and ask them how they would treat me, and ask them if #1 would fix my problem.
After I talk to a few orthos and learn what I can from them, I'm leaning toward #3. It will be SO much less expensive that I might as well give it a try. Even if it fails, I'm not out that much money. Worse case is I mess up my bite/teeth somehow. But, that wouldn't happen overnight. Teeth don't move that fast. So, I would watch things carefully and I may have to give it up and use a real orthodontist.
This PDF explains how Invisalign uses "precision cuts" to create elastic hooks and Button cutouts:
http://provider.invisalign.com/documents/PrecisionCuts.pdf
One thing that says is:
So, they use a button for the one that's pulling forward. I wonder why they can use a hook on the bottom tray for class III elastics, but not both the top and bottom. They must have a good reason. This concerns me. I wonder if there's not enough grip on the back molars. An advantage I might have is that I don't need to pull downward, I could pull straight forward, or possibly even an upward angle.
I was not planning to ask Invisalign if they would use reverse pull headgear. I'm assuming the answer would be no. There's a lot of information about Invisalign publicly available, and searching their whole site for headgear (and synonyms) returns nothing. If headgear was an option, I think their site would mention it. I still think it's possible. If you can pull against the bottom teeth, I don't see why you can't pull against reverse-pull headgear. Maybe they just haven't tested it yet. Maybe they would need to get FDA approval and maybe they don't think it would pay off. I'm just speculating.
I'll be curious to hear what you learn as well. Thanks.

I'm contemplating 3 options for my particular problem:
- Invisalign with class III elastics (ie: elastics between the top and bottom teeth, not headgear)
- Full braces with reverse-pull headgear (possibly in addition to class III elastics)
- DIY clear retainer tray, and I cut hooks for elastics that I use with my own reverse-pull headgear
