A 4.5x10 mm implant is placed at #3 subcrestal; the healing abutment is incompletely seated (Fig.2).  One month postop, the implant is infected with distal bone loss (Fig.4).  Bone graft is added.  Bone loss seems to reduce 4 months post implant placement (Fig.6 *).  Uncover is conducted at the site of #3; there is no superficial infection 7.5 months postop (Fig.8).  There is a large buccal defect upon incision with dark hemorrhage.  In fact the bone density is low crestally (Fig.8 *).  Bone graft is placed for the 2nd time.  Eleven months later (1.5 years post implant placement), the bone regrows crestal (Fig.9 *).  保险：愈合螺帽
