When a 4.5x10 mm implant is placed, it is difficult to use #2 sensor to take PA.  Finally a BW is taken with #2 sensor (Fig.1), while a PA is taken with #1 sensor (Fig.2).  CT is taken to show clearance of the implant from the Inferior Alveolar Canal (part of red circle; Fig.3 coronal section; B: buccal).
