The implant placement level seems to be ideal (Fig.3 after bone graft).  In fact a 4.5x4(3) mm cemented abutment is incompletely seated with a gap (<), probably due to interference from the mesial crest.  A profile drill should have been used.  There is foul smell from the immediate provisional; in fact it may be due to the loose contact between the implant and abutment (Fig.4 < (4 months postop)).  The gingiva is unhealthy.  A 5.5x5 mm healing abutment is placed.  When the patient returns 5 months postop, the gingiva is healthy after removal of the healing abutment.  A 4.5x4(4) mm cemented abutment is seated without interference and torqued to 35 Ncm (Fig.5).
