I guess the real question is how do you expect to keep your dental skills current during your 5 years of a pretty much all consuming ortho residency? I kind of get the impression that the program is probably geared towards creating a dual PCP/GP dentist for communities that are lacking in both.
OP; try going to medical school, dental school, or the combined program and then you will realize that it's not doable, and it wouldn't be desirable even if it were doable.
lol you'd be like a hundred years old by the time you finished training
Six years just to get the degrees (eight if not a combined program), plus four for OMFS plus seven for neurosurg= 17-19 years
