After placement of a 3.8x15 mm implant, PRF is laid against the inner surface of the buccal defect and allograft (Fig.5 *) is packed mainly in the buccal gap before and after insertion of a 4.5x5(4) mm abutment.  The bone graft remains in place 3.5 and 4.5 months postop (Fig.11,12 *).  Between 3 and 4 months postop, the mesial surface of the abutment has been trimmed (Fig.12 >).  Since the mesial surface of the tooth #10 will be reduced (white curved line) to correct the upper dental midline, an angled abutment (red line) seems to be necessary to shift the provisional distal.  The socket at UL1 seems to have healed except the most coronal 1 year 3 months postop (Fig.14 *).  The final crown has an open margin (Fig.16 > (nearly 1 year 4 months postop)), partially due to less ideal trajectory.  Guided surgery could solve the problem.  Sticky bone may restore the buccal plate defect.
