I'm planning to have orthognathic surgery soon, and the surgeon told me I can get my plates & screws removed after the jaw recovers. However, I want to know if there will be bad consequences to this?

The screws and plates holds the jaw in place, so if they are removed will the jaw shift? will it become loose? when i get older, will my jaws shift?

i actually want the plates removed b/c i don't want any metal in my body
