Mixture of autogenous bone from reamer, allograft and synthetic bone is placed in the mesiobuccal and palatal sockets before placement of the 6x17 mm implant (Fig.5 I).  Unfortunately some of graft blocks the apical osteotomy.  To clear the blockage, some of previous osteotome and taps are re-inserted.  The result is in fact beneficial, as bone graft (G) is pushed upward.  Prior to implant placement, nose blowing test does not produce air leakage.  P: palatal socket.
