The bone around the implant apparently remains stable between 2 and 4 years post cementation (Fig.6-8).  The patient requests extraction of the tooth #1 because of food impaction (Fig.9 black area).  To reduce post-extraction bone loss as related to the implant at #2, 3-D Bond (Fig.10 pink (hemostasis)), allograft (red (osteoinduction)) and Osteogen or Collagen Plug+Amnion-Chorion (green) will be used.
