From: A 3-year prospective randomized clinical trial of alveolar bone crest response and clinical parameters through 1, 2, and 3 years of clinical function of implants placed 4 months after alveolar ridge preservation using two different allogeneic bone-grafting materials

ai Shows the different steps of the socket preservation procedure. The initial radiograph (a) demonstrates a non-restorable tooth #12. The clinical appearance of the bony defect following careful extraction of the tooth is shown in b. c shows the augmented alveolar crest with a bone allograft material mixed with F-2 of the PRGF system and covered with a pericardium membrane (d). The clinical view after 4 months of healing is visible in e, at time of implant insertion (f). The radiograph after implant insertion (g), the clinical view of the final restoration (h), and the final radiograph 3 years following implant restoration (i) are shown
