Implant case thoughts?

Patient wants implants in the left lower quadrant. Both existing implants are failing. Thoughts?

Definitely explant both and socket pres! You could consider. a large GBR using allograft on the buccal surface or even a ridge split with grafting (less predictable). That would set you up for a 3-unit implant bridge

Tough case. Would require mini/short implants & a huge GBR. Guarded prognosis even with that
