Your question is predicated on the implicit assumption that your maxilla would need to be moved 1 cm. I have no reason to believe you're in the capacity to predict that. If you need me to assume you're in the capacity to predict that, then verify you have a ceph in front of you and you know how to analyze one and enough so to further clarify the vector displacements.
What is this 1 cm in reference to; the horizontal vector component of a longer diagonal distance needed to be travelled to get 1cm horizontal displacement and if so, what is the vertical displacement with reference to 'up' or 'down', OR does it refer to the total diagonal distance traveled? Is the orientation of your ANS-PNS already along a 'pure' horizont where you could move only in horizontal direction with no vertical displacement OR is this something where you would have to rotate ANS-PNS in order to move 1cm in a horizontal direction?
Your question itself, is inherently FLAWED and asinine. You think you need to move the MAXILLA 1cm and want to know if the ANS can be reduced by the same distance. Well, if you have to remove a segment of the maxilla the SAME distance it needs to be moved forward, then that's a 0 sum movement. You think you need to move the maxilla 1cm but you want to avoid moving it one cm, so you need to know if you can move the teeth instead.
You're either a dumb f**k or a clever narcissistic TROLL s**t posting stupid questions to see who assumes you have any valid basis for asking them.
