Well, if there is osseointegration failure, typically how it presents itself is that the implant is loose, no longer firm in the gum or bone. Otherwise, the implant is wobbly and it happens sometimes due to an infection.
So we always look out for swelling, pus, or abscess, anything that could indicate an infection in that area.
If the surgical site is infected and osseointegration occurs then I'm afraid the immediate implant has to be removed and we have to start all over again.
We remove the immediate implant, maybe put a bone graft in, and then we transfer the case to a delayed implant. So if the immediate implant fails the first time, for me, I will always have the second attempt be a delayed implant if the first one fails.
