I have a bar too and my surgeon said absolutely not. They can spread infection to your implant.
He then said I could never wear it again but when I had the op he said it seemed like a stable hole so once I had completely healed at about 6 months I could put it back if I really wanted to.
If you’ve gone through all that pain (not to mention money) it’s probably best not to risk it, I reckon. Or at least wait until you have no chance of infection.
