Hey guys,

I have been thinking about this for a while:

Conventionally, most use headgear like this ( )

in order to protract the maxilla, with the forces being delivered by elastics.

But what if we used something like this ( )

which is typically used for distraction in lefort 3 distraction osteotomies?

We would simply need to build some kind of intraoral appliance that encompasses a majority of the palate and/ or the teeth of the maxilla, and then have the pull be slowly adjusted by a quarter turn every week or so, until no more than 0.5-1mm is brought forward in one month?  I would understand there being the risks of maxillary fractures if the rate of forward pull is too fast, but I am unable to see the presence of this risk if this is done at a safe and slow pace.
