The trajectory is too late to change: when a 4.5x20 mm tap (T) is inserted, the trajectory does not improve (Fig.5). The first intraop PA should have been taken when a 2 mm pilot drill was 14-17 mm deep. A 4.5x20 mm implant is placed with insertion torque at >56 Ncm (Fig.6 I). A 3.5x3 mm abutment is placed and prepared (A).
