  • In the very least, a bone graft material should be osteoconductive. (wikipedia.org)
  • A bone graft material that is osteoconductive and osteoinductive will not only serve as a scaffold for currently existing osteoblasts but will also trigger the formation of new osteoblasts, theoretically promoting faster integration of the graft. (wikipedia.org)

(wikipedia.org)
  • socket
  • A dental implant is normally placed in the socket formed at the time of the sinus lift procedure and left to integrate with bone. (wikipedia.org)
  • After extraction, jaw bone has to be preserved to keep the socket in its original shape. (wikipedia.org)
  • Without socket preservation, the bone quickly resorbs resulting in 30-60% loss in bone volume in the six months after dental extraction. (wikipedia.org)
  • without the strain stimulus, the jaw bone behaves (with or without socket preservation) as if the space occupied by the tooth and periodontal ligament was empty. (wikipedia.org)
