Guided bone regeneration procedure was performed on the erratic extraction site (a–f). After a full-thickness flap was elevated, granulation tissue was noted filling the previously extracted site (a and b). Following thorough debridement and irrigation, the site was determined to be a containable defect (c). FDBA was gently packed in the socket and covered with non-cross-linked collagen membrane (d and e). Complete primary closure was achieved with a combination of horizontal mattress and single interrupted sutures (f).
