Abstract
A method for promoting the growth of bone, periodontium, or ligament in a warm-blooded vertebrate, the method comprising: producing a surgical flap to expose the bone, periodontium or ligament; debriding the bone, periodontium or ligament to remove organic matter from the bone, periodontium or ligament; implanting an effective amount of an osteogenic bone graft material, the bone graft material consisting of an osteoimplant having not greater than about 32% void volume formed at least in part from elongate bone-derived elements optionally in combination with bone powder; replacing the flap; and, allowing the bone, periodontium or ligament to regrow.
Claims10
A method for promoting the growth of bone, periodontium, or ligament in a warm-blooded vertebrate, he method comprising:
- producing a surgical flap to expose the bone, periodontium or ligament;
- debriding the bone, periodontium or ligament to remove organic matter from the bone, periodontium or ligament;
- implanting an effective amount of an osteogenic bone graft material, the bone graft material consisting of an osteoimplant having not greater than about 32% void volume formed, at least in part, from elongate bone-derived elements optionally in combination with bone powder;
- replacing the flap;
- and,
- allowing the bone, periodontium or ligament to regrow.
A method of providing selective influence on tissue regeneration in the vicinity of a periodontal defect, said method comprising the steps of
- separating soft tissue from at least a portion of the surface of a root of a tooth located at the defect, the portion comprising that area of the root surface located adjacent to the defect;
- and
- affixing to the root surface an osteoimplant having not greater than about 32% void volume formed at least in part from elongate bone-derived elements optionally in combination with bone powder and having one surface that is impermeable to soft-tissue cells;
- and,
- tightly affixing the osteoimplant near or slightly apical to the cervix of the root to prevent the growth in an apical dire ion of soft tissue along the root surface.
