Haha I actually tried this recently and wondered why nobody else has talked about this then I see this thread , weird. Yeah I think it’s not a bad idea just don’t push too hard as it’s near the tmj, I ended up using too much force and had pain 

How exactly would one execute this? Putting ones thumbs between the cheeks and teeth and push upwards towards the zygomatic bones?

@loliboly

I'd imagine pushing up on the zygomatic arch from within the vestubular area (i.e. inside cheeks, like you said) would result in upward motion only.  I'd be curious if anyone is able to squeeze their fingers inside the arch from this area so as to get some forward force (and not purely upward).

Something else occurred to me; even if you could pull the zygomatic arches and maxilla forward, wouldn't the pterygoid junction at the posterior of the palatine process prevent forward traction?
