The ridge at the sites of #6 and 7 looks wide, but the bone is narrow (~ 4 mm) when the flaps are raised. Two of 3 mm 1-piece implants (3x16(2) and 3x14(4) mm) are placed (Fig.1,2). The other advantage of use of 1-piece implants is the narrow mesiodistal space. In fact the gingiva is wide and thick (4 mm). It is ideal to place implants with 4 mm cuff; unfortunately there is no 3x16(4) mm implant available at the site of #6. After adjustment of the abutment at #7, a splinted provisional is fabricated.
There is no bone loss 3 months postop (Fig.3, probably due to the hard bone).
