Following sequential osteotomy, a 4.5x10 mm implant is placed 2.3 mm from the neighboring apex (Fig.4).  A 5.5x5(4) mm abutment is placed immediately and allograft is placed in the remaining sockets (Fig.4 *).  The bone graft settles down and remains in the distal socket 2.5 months postop (immediately pre-cementation, Fig.10 *).  The bone graft appears to prevent implant threads from being exposed 2 months post cementation (Fig.11).  The bone density in the distal socket increases significantly 8 months post cementation (Fig.12 *).
