摘要: A demineralized bone matrix (DBM) or other matrix composition is provided that has been stabilized by lowering the pH of the composition, reducing the water content, adding water substitutes, and/or increasing the amount of deuterated water present in the composition in order to reduce the activity of endogenous degrading enzymes such as proteases. A hydrated form of a stabilized DBM composition may be stable up to a year at room temperature at acidic pH. The acidified DBM compositions may be further stabilized by the addition of a stabilizing agent such as deuterated water, water substitutes, polymers, protease inhibitors, glycerol or hydrogels.

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.
摘要翻译: 提供了一种制造骨诱导性骨植入物的方法,其包括以下步骤:将至少一个皮质骨整体部分的至少一个表面的部分或全部软化至至少约100微米的深度; 以及配置皮质骨的整体部分以提供具有外表面的骨植入物,所述外表面具有至少一个脱矿质区和非脱矿质区。 根据上述方法制备的植入物表现出改善的骨诱导,而不会在骨植入物的临界区域中产生任何临床显着的强度降低。
