I agree if there are minor (very minor) issues then invisalign will probably be ok. I have seen people with a lot of spaces between thier teeth get invisalign and it looks horrible, because you can see the plastic where the spaces are. Those people should have gotten braces. Plus I hear it takes a little bit longer depending on the the persons teeth.
Our ortho uses them as retainers--he says that they do a good job of keeping teeth in place, but don't work as well as old fashioned brackets and wires for moving teeth. My older kids had them for retainers for 5 years or so, and both now have regular wire retainers. After awhile, they didn't feel like they held their teeth in place anymore.
I think you have to get new molds done every couple weeks or so. Sounds like a much bigger PITA than plain old braces.
