Can implants be rejected from the human body?
No, they can not. Implants are made of titanium, also called as medical metal that does not generate any reaction of the immune system, consequently, rejection is impossible. Sometimes implants become loose and they fall out, but this happens only when osseointegration is disturbed for some reason and the chance of this is minimal and happens very rarely in case of proper implant planning and surgery. Usually, this can be sorted out with a second implantation surgery within weeks.
