So I suspect the implant was placed in cortical bone at the top and the lack of blood supply caused this die off. It could also be the lack of KT thickness. This is why I routinely place my implant 2mm subcrestal. At this point I don’t think there’s anything that can be done. It’ll be ok, just something to remember for next time.

It doesn’t look like it will be a problem. Some of the graft turns over into natural bone–but some (like the graft stuck in soft tissue shown above your implant) will not turn over. It’s ok.
