The site of #9 has a short pointed ridge and a wide base (Fig.6); a 1-piece angled implant (3x14 mm 15 °) is placed palatally (Fig.7).  Start osteotomy with 1.2 mm drill as palatal as possible at the ridge.  The apical end of the ostoeotmy is also slightly palatal.  With 15 ° angulation, the trajectory for restoration will be more or less ideal.

Keep the 1.2 mm drill in place (initial depth 12 mm) for X-ray.
