Anyone hear about that bone loss study?

A few weeks ago, there was a post in here about bone loss in your upper jaw from pressure of a nasal mask. is it really true? I'm still off and on with my nasal mask and can't stand the nasal pillows I have (I beleive it is the Breeze.) I'd love to be able to use a couple of different type of equipment, as the line on the bridge of my nose is almost permanent now.

I have not heard anything about this but it certainly sounds like a worry? Where did you hear about it? Has anyone else heard anything?
