As to ditterbo's comment to you:
I can't opine on 'enough CCW'. But based on looking at the 'after' RIGHT skull diagrams and measuring (approx) the angle of the mandibular plane RELATIVE to a HORIZONT, my (hand held protractor which is not going to be 'exact') has approximated about 34 degrees for the before skull and about 28 degrees for the after skull. So the RELATIVE DIFFERENTIAL for CHANGE in mandibular plane angle is about 6 degrees and that is in the DIRECTION of CCW.
Also, when we look at the DIRECTIONS of the DISPLACEMENTS in the chart, we see POINTS like the; 'ANS', 'A', 'B' and 'Pog' all moving in the UPWARD (vertical) DIRECTION in addition to being moved in the (horizontal) Anterior direction. So, those two directional displacements TOGETHER are in direction of CCW, upward and out.
Since your lower jaw and chin are BOTH recessive, those areas will improve aesthetically with the forward advancement to BOTH. Advancing the lower jaw forward, more often than not is first CONTINGENT on moving the upper jaw forward. Since the mandibular plane angle in the skull model had been DECREASED about 6 degrees in direction of CCW, that basically indicates the upper jaw will be moved in direction of CCW. Since I don't see any slices removed from it or slices added to it, I'm assuming your natural orientation of ANS-PNS (maxilla is already inclined in CCW direction). Given that the PRIORITY here is to RELIEVE you of SLEEP APNEA, I would conclude that 'enough' displacement of both jaws and chin was planned in there for what has to be PRIORITIZED and also enough to give you much better aesthetic projection to both the chin and lower jaw.
Sometimes in sleep apnea cases, the upper jaw can look a bit protrusive if it has to be moved more than ideally optimal to accommodate the lower jaw advancement they need to do in which case, you might see nose changes and changes to the upper lip area. Can't predict what those will be from here. Just to say that IF they are unfavorable, adjustments to contours can often be done later down the line by plastic surgery techniques.
As to 'someone....'s' comment to you, you don't have same thing she had (a situation where they needed to move downward) and if you look at the directions in the chart, they are all moving upward. Given that a genio is part of helping to address the sleep apnea and that chart indicates your chin point will be moving UPWARD and not downward as in her genio, you were wise to realize you didn't have to worry about getting the genio aspect of it.
