RCT Retreat or Extract?

A 52-year-old woman has had chronic abscess associated with the tooth #3.  The palatal root is exposed (Fig.1 P), suggesting root fracture.  The apex of the mesiobuccal root seems to stick out of the buccal plate (Fig.2 *).  The root canal filling is incomplete in the distobuccal root (Fig.3 *).  The tooth appears to have guarded prognosis.  Extraction and immediate implant is apparently a better option (Fig.4,5).  It would be safer to start osteotomy in the middle of the remaining septum (Fig.6, as compared to Fig.5).  After sinus lift with PRF membrane (Fig.7 yellow curved line) and implant placement (green), another piece of PRF membrane will be placed against the palatal wall of the socket, followed by bone graft (red circles) and a 25-degree angled abutment (pink).
