DBM compositions, methods of making and methods of treatment with the same are provided. The DBM compositions are made from mechanically entangled bone material that does not contain a carrier. The coherent mass of mechanically entangled demineralized bone fibers can be obtained by needle punching with barbed needles, entanglement with water or air jets, or by applying ultrasonic waves to the demineralized bone fibers. A coherent mass of mechanically entangled demineralized bone fibers can also be obtained by application to demineralized bone fibers of moisture, heat and pressure provided by pressure rollers. A method of making a bone material for hydration with a liquid is also provided. The method includes subjecting demineralized bone fibers to mechanical entanglement to obtain a coherent mass of demineralized bone fibers in the absence of a carrier.
