The trajectory at #10 with 1.2 mm initial drill is also unsatisfactory (Fig.6) and needs a drastic change in trajectory (Fig.7).  In fact the position of the osteotomy needs to be changed (distalized) in order to change the trajectory (Fig.8 arrow (most likely 1.5 mm drill)).  Distalization is more obvious (probably due to angulation of X-ray taking) when a 2x14(2) mm implant is placed (Fig.9 arrow).
