After implant placement, Osteogen plug (Osteogen: Bioactive Resorbable Calcium Apatite) is inserted into the 3 sockets (mesiobuccal, distobuccal and palatal) until the plateau of the implant, while Collagen plug (Fig.5 C) is placed in the socket between the implant plateau and the abutment margin.  It is hoped that the former facilitates bone regeneration, while the latter gingival regrowth (to correct gingival recession).  No allograft is apparently used for socket filling, although it cannot be ruled out that the bone graft used for sinus lift is not pushed accidentally into the sockets.  More allograft should have been used more and preferably in sticky form.
