Break the Matrix

I wouldn't lump belt pulling in with palate expanders. Bumping intermolar width up by 3-4mm is not uncommon with them.

I've yet to see anyone with results from face pulling. I'm not even sure where the face pulling theory comes from, but I don't believe it's practiced by any doctor - while adult palate expanders are. It just depends on what we're talking about here.

If you're trying to go from an intermolar width of 36mm to 42mm, that may be achievable with a DNA appliance or Homeoblock appliance. But if you're sitting at 33mm and need 46mm, lol no way way no how. You're in SARPE or bust territory.
