    摘要: A method of manufacturing an osteoinductive osteoimplant is provided which comprises the steps of: demineralizing part or all of at least one surface of a monolithic section of cortical bone to a depth of at least about 100 microns; and, configuring the monolithic section of cortical bone to provide an osteoimplant possessing an outer surface possessing at least one demineralized zone and a non-demineralized zone. An implant produced according to the above method demonstrates improved osteoinduction without producing any clinically significant reduction of strength in critical regions of the osteoimplant.

    摘要: 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.
