How to place the immediate implant in the middle of the septum?  In addition to the slot in the middle, the smallest pilot drill should be used for limited depth and an early intraop PA should be taken (Fig.6).  If the deviation is noted (Fig.6 red long arrow) in the septum (S), it should be corrected before using the next drill (Fig.7).  The osteotomy should be as deep as possible so that the larger drills can be stable even though the coronal portion of the septum is perforated.
