CCW of the jaws and the chin. I think that movement would make the philtrum more concave.
With regard to movement size, I'd guess 13mm minimum, but I'm not sure. The average first molar is around 17mm and premolar 8mm, so you can sort of guess based on that.
Although there will be more charts where they measure average dimensions of teeth that I'm showing here than I to care to ferret out, can you clarify which dimension you are referring to as to average first molar?
I'm assuming you mean the medial-distal CROWN WIDTH of it given that dimension would relate to direction of'advancement' (as opposed to the facial-buccal width). Yes?/No?
If so, 17mm ave mesial-distal crown width well exceeds the maximum found in the second chart. Also, if you look at RULER for 17mm, intuitively, it would be an excessively wide tooth.
How did you come up with 17mm and if not medial-distal crown width, what dimension does it refer to?
