The wound reduces nearly 3.5 months postop (Fig.7).

There are two layers of the bone, one (1) being denser than the other (2) 8 months postop (Fig.8).  After local anesthesia, the healing screw is removed; the implant is found to be stable.  A 6x4(2) mm pair abutment cannot be inserted due to blockage of the mesiobuccal gingiva (Fig.9 *).  Instead a 6x2 mm healing abutment is placed.
