To obtain the best recovery, socket preservation is carried out with 50/50 cortical/cancellous allograft mixed with Osteogen and Collagen Dressing (Fig.9: #12). A 2 (or 3)-unit bridge is fabricated over the implant (I)/abutment (A) at #13. The distal surface of the tooth #11 is being acid eteched in preparation for bonding.
