Following the last drill (3.8 mm) for 11 mm, a 4.5x11 mm dummy implant is placed 2 mm subgingival (Fig.2; *: space of the palatal socket).  In fact the sinus lift is done by the implant, since the bone plug after Magic Drill is present in the apical portion of the osteotomy when the last drill is finished prior to implant placement.  After the dummy implant is removed, the definitive one (the same size) is placed with >50 Ncm, followed by placement of a 4.5x4(3) mm abutment and VeraGraft mixed with autogenous one (Fig.3 *).  VeraGraft granules are finer than Vanilla one (.25-1 mm vs. .5-1 mm).
