The implant is then placed ~ 4 mm subgingival (Fig.8) and slightly subcrestal (Fig.9,10).  It appears that the 3.5 month postop bone loss (as compared Fig.1,2) makes the implant look to be placed too shallow.  When the implant is being placed deeper, the buccal plate feels intact.  The early periimplantitis is apparently due to postop bone loss more than buccal placement, although certain degree of buccal bone resorption must occur.
