@zygomidus bro the maxilla doesn’t need to “rotate” it just needs to grow. So called downward growth is just lack of growth. If that’s the case then how come we don’t need any constant force to grow our clavicles, long bones, ribcage. It’s 100% nutrition and epigenetics. 0% habits.
Any so called “bad habit” is just a symptom and correlational. Bad posture comes from poor growth, bad tongue posture is only because the palate is too narrow due to lack of nutrition.
