Ghost Marrow,
Residual Sockets, Residual Inter-dental Trabeculae 

Residual sockets or laminar rain remaining years after extraction are a hallmark of chronic ischemia of jawbone marrow.  Here there has been so little remodeling that even the inter-dental trabeculae (Jacob's ladders) remain.  The hazy, faintly ground glass-like appearance of the inferior portion of the film has few trabeculae and represents "ghost marrow," a common radiographic feature of osteonecrosis of long bones.
