right now from the side i have an okay ramus almost ideal but a lot of downward growth with my mandible and not a lot with my maxilla it is very flat almost recessed even though i’ve never mouth breathed or had bad habits growing up and it’s mainly genetics , i’ve heard about thumb pulling before but i’ve been told its cope and it doesn’t actually work. my last resort is to get MARPE or a palette expander but those are kind of expensive and i would rather grow my maxilla forward using something that isn't going to cost a shitload of money, any suggestions?
