A 5.9x10 mm bone-level implant is placed with insertion torque ~ 55 Ncm (Fig.8).  The coronal gaps (Fig.8 *) are filled with allograft and Osteogen (Fig.9 *); a 6.8x4 (3) mm abutment (Fig.9 A) is placed for an immediate provisional.

Six months later, the provisional perforates on the top of the abutment.  It suggests that the patient has chewed with the provisional.  When the provisional is removed, the occlusal clearance appears to have been reduced, suggesting that the opposing tooth has supraerupted.  However, osteointegration and bone regeneration at crest have not been disrupted (Fig.11).
