With 6 mm clearance, block anesthesia is administered.  A 5x10 mm definitive implant is placed with ease (Fig.3).  The buccal bony defect is repaired by allograft (*).  The abutment has been dislodged (because of incomplete seating, Fig.3) for 2 week (Fig.14 (3 months postop).  The bone graft, albeit decreased, is 2 mm subgingival (red dashed line).   There is no bone loss 2 years postop; the UF abutment is completely seated (Fig.16).
