A 5x11 mm IBS implant is placed with insertion torque of >45 Ncm, followed by insertion of a 6.5x4(2) mm abutment (Fig.4 A).

Four weeks postop, the 6.5x4(2) pair abutment is found lingual and changed to angled one 5x2x15º.  After adjustment of the abutment height, temporarization is made with clearance.  The patient returns for final restoration 3.5 months postop; there is minimal crestal bone resorption (Fig.6 (AA: angled abutment)).  The crown is recemented 1 year 4 months post cementation, most likely related to implant lingual placement (Fig.7).  The bony trabecular structures are more distinct and dense around the coronal end of the implant.
