Since the gingiva is as thick as 7.5 mm (Fig.3 arrow), a 3x14 mm 1-piece implant with 4 mm cuff is placed (Fig.5); three implant threads are outside the native bone; with allograft (*) placed and the neighboring crests being coronal to the threads, the chance of periimplantitis should be remote.  An immediate provisional is fabricated to contain the graft in place.  The top 3 threads appear to be contacted by the newly formed crestal bone 6 months postop (Fig.6 *).  Bone appears to have grown into the space between implant threads 6 months post cementation (13 months postop).
