Trajectory is found to be off when 5x9 mm dummy FC implant is placed with stability (Fig.5 (*: defect)).  The final implant, Magicore (5x7(3)mm, >29 Ncm), appears to be placed too deep for restoration (Fig.6,7); a screw retained crown may be a solution.  PRF membrane and Vanilla (allograft) are used for sinus lift (no sinus membrane perforation).  Following Vanilla graft in the socket gap (Fig.6 *), another piece of PRF membrane is used to cover socket opening.  The membrane is fixed in place with suture and periodontal dressing. When a FC implant is placed too deep, a pair abutment with longer cuff will solve the problem.  With Magicore, the diameter of abutment is unable to change.  The implant seems to have osteointegrated 3.5 months postop (Fig.8).  After change to 4.3x5 mm solid abutment and mesial surface adjustment, impression is taken for early loading because of removal of #14 implant.  In fact the patient is satisfied with mastication improvement at #2 later on.
