A 5x10 mm implant is placed at #31 apparently deep (Fig.3).  A 6.8x6 mm healing abutment is placed.  There seems to be no clearance between the abutment and the crestal bone 3 months postop (Fig.6 *).  The cemented abutment for the site should be substantially smaller!  A 5.3x4(4) mm one appears to be completely seated; the clearance from the crest (Fig.10 *) is minimal.  The abutment seems to remain in place immediate post cementation (Fig.11).
