Immediately after extraction, a 4.5x17 mm tap is inserted with stability (Fig.4 white box).  Clinically the apical portion of the tap appears to be deviated buccally.  An osteotomy is created in the apicodistopalatal socket (Fig.4 red line) until 3 mm.  When the same tap is re-inserted (Fig.5 T with stability), it does not apparently go to the osteotomy (dashed red lines).
