Since the Inferior Alveolar Canal is invisible (Fig.1,2 (pan should have been taken)), a 5x11.5 mm implant is placed with <20 Ncm.  When a 6.5x5.5(3) mm abutment is placed, the underlying implant is turned (Fig.3).The patient returns for uncover 8 months postop; although the implant has osteointegrated apparently, the crestal bone resorbs to the implant plateau level (Fig.6 arrow).  It seems that the immediate implant should be routinely placed 2-3 mm deeper.
