Break the Matrix

From my perspective studying it, I don't think face pulling is any more likely than NCR/endonasal inflations to bring the mandible forward. If it comes forward it should be because the temporozygomatic arch (maybe the entire zygomatic process) shifts laterally and that's just as likely to happen from NCR/inflations as face pulling.

The condyle/round part where the mandible connects into a socket in the back - there's a disc/connective tissue in there and ligaments holding connecting that part of the mandible to the temporozygomatic arch.. If the zygomatic arch moves out laterally the ligaments "loosen" or extend slightly over time and that's what could pull the mandible slightly forward. It's prob a little bit more complicated and I could be wrong it's just the only thing that makes sense to me.

You can see better on this photo, the stylomandibular ligament
