Alginate impression will most likely dislodge #11-15 loose FPD.  Start osteotomy at #11 and 15 first (Fig.6, 10) and use the teeth #9 and 10 as trajectory reference.  Prepare PRF (Fig.10 white curved line) and Magic Lifter for #15 (2 mm bone).  Red circles: bone graft.  Bone graft will be placed around the coronally exposed threads.

Then use Magic Split (flapless) and Magic Expanders for #13, since bone density is between 150-800 (Fig.8).   Since the gingiva is thick, use the longest cuff of cemented abutments (5 mm).
