With placement of Osteogen plug (presumably for repair of the perforation) and limited amount of Vanilla at the osteotomy, a 5x7.3 mm IS implant with SLA surface treatment is placed (Fig.2, ~ 40 Ncm).  When the implant is further seated (Fig.3 arrow with bone graft coronally *)), its trajectory is within the normal limit (Fig.4 blue line).  If the implant fails again, it must be due to the mild sinus infection.  Bone graft should have been done first.
