It certainly can be a problem for the immunocompromised. Of course
there's no way to completely exclude bacteria from the surgical site.
You certainly don't want to introduce any new ones.
Occasionally you will hear of an implant that fails to integrate, and
contamination is of course one possible explanation. But just as other
hard and soft tissue surgery can be done in the mouth with success, so
can implant placement. But nothing is 100%, and that includes implants.
