By the time a 6x20 mm implant is placed, the insertion torque is 60 Ncm (Fig.8).  Prior to implantation, the sinus floor is found to be intact without air leakage.  There is a mesiobuccal socket defect (*).

The patient returns 3.5 months postop (Fig.11), requesting final restoration, because of loose provisional.  The density in the mesiobuccal socket remains low (*).  There is no mesial defect 14 months (Fig.19 *) or 32 months (Fig.21) post cementation.  In fact the bone density increases mesially.
