If one were to use a headgear to protract the maxilla, what should be the vector of the elastic pull (to the occlusal plane) if a purely forward movement is desired? Most studies on maxillary protraction involve a downward and forward movement of the maxilla, rather than just purely forward movement, and because of that there is a clockwise rotation of the mandible.
Thank you for this. I have attached a diagram to this comment. Would -30 degrees to the occlusal plane of force application achieve #1 or #2 on the diagram? If it is #1, how would one achieve something like #2?
is this how you mean it?

#1
#2 achievable through remodeling of existing bone mass over time

Yeah
@ varbrah
So if one wanted that kind of movement in #2 they would probably have to protract -15 degrees to parallel to the occlusal plane (According to FEM models)?
