Socket preservation is a procedure to preserve the alveolar ridge after tooth extraction by placing graft material in the extraction socket. The Bio-Col technique and socket seal surgery are two approaches that involve placing graft material and membranes in the socket to promote bone and soft tissue healing. These techniques aim to minimize ridge resorption and collapse of soft tissues after extraction. Case studies demonstrate that both techniques can successfully preserve the alveolar ridge contours and thickness for later implant placement or prosthetic restoration.
