To have thicker buccal bone, the 5 mm implants at #18 (Fig.2) and 19 (Fig.3) seem to be a little large.  Smaller (4.5 mm) will be more appropriate so that the coronal threads of the implant at #18 will be more securely covered by the regenerating bone.  In the same manner, the implant to be placed in the healed site of #19 will have more buccal bone when the diameter of the implant reduces.  IBS FC implants have sharp fins, which exert minimal pressure on the cortical bone to cause bone resorption.
