There are studies showing 5mm expansion from tongue training in adults. I myself expanded from 35mm to 45mm. I also have had a lot of forward movement of the maxilla which caused my chin to follow. Just cause you quit halfway doesn't mean it doesn't work, it will take 2-5 years to start noticing an actual difference, the changes are very slow.Mastic gum will not help, mewing does not work unless you are under 13 years old kid who hasn't hit the puberty yet. Studies were shown that mewing works on CHILDREN pre-puberty but in no way it works on adults.
1st post is the rules, 2nd post wont let me see what it is. So this is the 1st post tbhChin for me due to how recessed and underdeveloped it is, what about you?
My surgery plan is getting a sliding genioplasty, seems like results are more prominent with sliding genioplasty rather than implants based on all the pictures I have seen, what do you think?
