earl I'll be straight up with you. the DNA appliance is meh, I dont want you to waste your time.
Its basically a palatal expander. It has bite blocks so if you wear it over a long period of time it'll create a posterior open bite. IMO, the ALF appliance and the orthotropics expander are better. They all do the same thing, light long-term forces changing bones. If you really want to increase bone density it seems like chewing would do that. People's dominant arms are actually thicker and more dense. I believe if you dont use it you lose it. So the more you chew and put stress on your upper and lower jaws the more the body has to compensate in making it more dense and strong.
