I did an immediate implant placement on the lower right hand side first molar on Jan 4. 
 
I placed allograft 50/50 allograft and membrane over the implant. 
 
Cover screw and buried the implant.
 
It’s a Biohorizons 5.2 by 9mm 
 
Following up with the pt. 
 
I noticed the membrane was gone about a week after the surgery. I think the sutures didn’t hold and he lost the membrane and some of the bone grafting. 
 
Now a month later, the implant cover screw is exposed….
 
I’m not sure what to do? 
 
Take the implant out? And graft the site? And redo 5-6 months later? 
 
Attempt to take the cover screw off and regraft?
 
Please help
 
Pt is such a nice guy

Is there crestal bone loss?? 
 
 
The radiograph taken today which is this one seems like there’s bone loss at the top

Update on this case: 
 
I ended up going in and replacing the cover screw with a HA 
 
About a month after 
 
 
5 months later and saw the pt for a recall

That looks pretty good doesn’t it? For healing? 
 
I don’t have a Pa but I will take one after they come back next month for review
