front

It looks like you have a slight canted arch on the lower.  I’m not sure how to deal with that... you can widen the top with some awesome treatments like Alf, Sue Lee’s device or possibly wireframe DNA... but these are pretty rudimentary in development from what I know.  Pair Alf and Sue Lee with braces.  But if you disarticulate your maxilla then the top would match the lower (slope right more). I truly believe in having #1 great health # 2 nice face # 3 decent teeth.  I wouldn’t trade #2 for #3.  If #1 is a problem, I’d look at other ways to resolve.  There are various ways to address airway/mental health stemming from airway.  I am excited about this field and growth in this area!!  Regardless, I’d get free CBCT somewhere.  Here are some potential places (not sure they are all complimentary): /community/community/main-forum/3d-cbct-airway-orthodontists/#post-10386

How did you measure IMW?  I like this way...

Seems to work better with a flat bell pepper, though.

Yeah main case why i want a expansion is because i can't breath while mewing and i touch my molars with it 

I measured it on paper and on a banana hahah 

And i already searched for an Alf or a Fagga or DNA but only they got in the netherlands is a Hyrax expander but i don't know if that is really what i need 

And the cantel arch is i think because one of my teeth was stuck twice at the maxilla so it could get down so they removed it
