I just want to comment on Invisiline. I am currently about 9 months into my invisiline braces. I didn't have radiation - so that wasn't an issue for me - but want to let those of you know this if you are considering it.

Invisiline braces do cause irritation of the tongue when you first get them. My tongue was very sore and raw from rubbing on the sharp plastic for a long time - the plastic trays fit tightly down over the front and back of the teeth. You can file the edges down with a nail file- but it doesn't really help all that much. You will probably still be very sore.

In saying that: I just want to warn people who are thinking of it - that if your tongue is still the slightest bit sensitive still after radiation - or if b/c of the radiation - it might not heal well if it gets cut - I wouldn't get them.

On a positive note: They do increase my salivary output. I had salivary glands removed for my surgery and am left with very dry mouth - the braces increase the saliva so that the dry mouth is a little less than without them in.....

Thats just my personal experience - and thought I'd share for those of you considering them.
