The papilla is restored in a normal position with placement of a 4.5x11.5 mm implant (with guide, ~ 1 mm deeper than designed because apparently excessive buccal thread exposure intraop), a 5.2x4(5) mm cemented abutment (Fig.3) and mixture of cortical bone (125μm – 850μm) and cortical/cancellous bone (.5-1 mm) with PRF (sticky bone, B in Fig.4-6).  No space for mesial sheath.   With use of bone trimmer, it is possible to place an implant in the septum so that the mesial sheath is achievable.
