Section FPD Twice

A 64-year-old woman has a lower left FPD (Fig.1) with the abutment at #20 having open margin (*).  The tooth seems to be non-salvageable and to be replaced by an implant.  There is ~ 6 mm native bone (Fig.2).  Mesial osteotomy should be safer than orthodox one (Fig.3).  To have the best reference, the FPD will be first sectioned between #19 and 20 (Fig.3 red line).  Initial depth will be 18 mm (gingival level).  An implant will be placed using the pontic at #19 and the tooth #21 for orientation guide.  After placement of an abutment at #20 and use of gauze to seal the socket, the FPD will be sectioned between #18 and 19.  It appears that the tooth #20 and probably #18 have fractured (Fig.4).  Implants will be most likely placed at #18 and 20.  The existing bridge will be used as a provisional.
