I believe a premolar is 8mm, from memory.

You probably wouldn't get that much advancement from extracting the lowers alone because teeth would rotate and whatnot to close the space. I'm not sure what exact mm advancement you'd get from that. Take notes from this thread and bring them to a surgeon to ask.

What do you think would be an advancement that would give a promising result? 1cm? And do you recommend a genio? The skin on my chin seems to be very thick.

You already have a prominent chin. It may actually need to be reduced if you advance the lower jaw.

If i bring my lower teeth infront of my upper teeth in a underbite position my jaw still looks recessed from a side profile. Does that mean i will need a really large advancement to get a proper result?
I kinda like my chin because it looks my big nose look a little better.
