When a longer implant is placed (5x11 mm), it does not easily enter the osteotomy, either sliding into the mesial or distal socket with the implant separating from the implant driver.  It appears that a premount implant is appropriate in this situation.  When the 5x11 mm implant is finally seated with stability, it is 6 mm apical to the gingival margin.  The longest cuff of IBS abutment is 4 mm.  A longer implant is needed (Fig.7, 5x13 mm).  Placement is not easy as mentioned above.  Insertion torque is <20 Ncm when the patient experience a little discomfort.  A 6.5x4(4) mm pair abutment is placed (A), apparently proper for restoration.
