The discharge relapses.  It appears that the apex of the implant (5x16 mm bone-level) should be truncated for 3-5 threads (Fig.11 black line).  Soak a piece of 2x2 gauze in Metronidazole; it will be used to hold the implant outside the mouth for sectioning.  Prescribe Medrol dose pak to reduce postop edema.
