When chewing your masseter does most of the work. When the masticatory process starts the muscles deliver tension at 3 places i.e. the body of the mandible, the zygomatic arches and the temples. This causes the saggital development of chin, zygomas and the brow ridge respectively... how?
When the masseters apply forces to the three stated above, it causes microcracks which in the end results with added bonemass (in the saggital plane) on the locations stated above. Basically the actual increase/decrease in ipd isn't because the ''upper maxilla'' is too narrow or too wide, it actually depends on the saggital bone mass deposited on the front of the cheekbones.
Proof?
Every lefort 3 surgery ends up increasing ipd of the patient from third person view. How? Because the cheekbones move forward on the saggital plane as seen above.
TLDR:
Low ipd- get your cheekbones repositioned forward or chew for next decade at least 3 hours a day.
High ipd- stop chewing a lot and get your cheekbones repositioned backwards.
