In regards to removing screws from genioplasty surgery, is this safe to do?

Hi there, I did a genioplasty in January 15th 2018. I was aware that the surgeon would place some screws however I was not so aware of possible long-term effects of screws in the body and now I want to remove them. My surgeon does not recommend but I want to do it anyway. Is this possible? How is the process? How is the recovery? I live in UK therefore opinions within UK or Europe would be much appreciated, although i might consider travelling anywhere.
