They contain very little metal, so will not set off any metal detectors. I have a similar sized implant, but not this one, and have no trouble at airports.

The metal detectors at the airports I've been to can't seem to pick up small pieces of metal eg. metal usb sticks[1], or small coins.

To be fair they are probably used to similar situations. Plenty of metal fixings in people today.
