A 66-year-old man returns with chief complaint of chewing pain lower left.  There is severe bone loss around the implant at #19 (Fig.1,2).  Section the crown, remove the 6 mm abutment (no cement) and 7 mm implant.  After debridement and copious irrigation, place Augma, press, place Collagen plug and 4-0 PGA.  Take PA and place acrylic or periodontal dressing if needed.   Is the defect too large for 1 cc Bond Apatite?  Place allograft in the bottom of the defect before Bond Apatite?
