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).
