The initial osteotomy depth is 16 mm (Fig.5); the trajectory is going to be adjusted as shown by arrows.  The trajectory improves when a 3.8x15 mm dummy implant is placed (Fig.6).  The definitive implant (3.8x16 mm) appears to be placed at an appropriate level (Fig.7).  A 4.5x3 mm temporary abutment is inserted for an immediate provisional.  As routine, Vera Graft is placed in the buccal gap.  Although the provisional. is unstable, there is no bone loss 2 months 20 days postop (Fig.9).  Check Trajectory Last Next Xin Wei, DDS, PhD, MS 1st edition 03/01/2018, last revision 07/25/2018
