wherein upon rehydration for a period of about 1 hour to about 6 months the bone fiber-based product returns to from about 60% to about 100% of at least one characteristic selected from the group consisting of its pre-dehydrated shape, its pre-dehydrated flexibility, its pre-dehydrated compressibility, and combinations thereof.
22 . The shaped, bone fiber-based product of claim 21 , wherein the void to fiber ratio is from about 1:99 to about 1:11.
23 . The shaped, bone fiber-based product of claim 21 , wherein the residual moisture content of the product is less than about 6%.
24 . The shaped, bone fiber-based product of claim 21 , wherein the product is bendable to about 90° when rehydrated.
25 . The shaped, bone fiber-based product of claim 21 , wherein the product is at least about 90% as intact when rehydrated as before dehydration.
26 . The shaped, bone fiber-based product of claim 21 , wherein the product when rehydrated remains greater than about 90% intact after being bent, compressed, twisted, squeezed, and/or rolled.
27 . The shaped, bone fiber-based product of claim 21 , wherein the product is not a putty when rehydrated.
28 . The shaped, bone fiber-based product of claim 21 , wherein the bone fibers comprise at least one growth factor selected from the group consisting of IGF-1, BMP-2, BMP-4, BMP-7, and combinations thereof.
29 . The shaped, bone fiber-based product of claim 28 , wherein the at least one growth factor is native.
30 . The shaped, bone fiber-based product of claim 28 , wherein the at least one growth factor is selected from the group consisting of IGF-1 in an amount greater than 60 pg per gram of demineralized bone matrix, BMP-2 in an amount greater than 2700 μg per gram of demineralized bone matrix, BMP-4 in an amount greater than 200 μg per gram of demineralized bone matrix, BMP-7 in an amount greater than 9000 μg per gram of demineralized bone matrix, and combinations thereof.
31 . The shaped, bone fiber-based product of claim 21 , wherein the fibers are entangled with at least one material selected from the group consisting of wood, food, plant-based material, at least one elastomer, at least one thermoplastic, and combinations thereof.
32 . A shaped, dehydrated bone fiber-based, comprising:
a plurality of at least partially demineralized bone fibers,
wherein an average length of the plurality of partially demineralized bone fibers is between about 1 and about 200 mm, and
wherein biocompatible materials are entangled within the partially demineralized bone fibers.
33 . The shaped, bone fiber-based product of claim 32 , wherein the void to fiber ratio is from about 1:99 to about 1:11.
34 . The shaped, bone fiber-based product of claim 32 , wherein the residual moisture content of the product is less than about 6%.
35 . The shaped, bone fiber-based product of claim 32 , wherein the product is bendable to about 90° when rehydrated.
36 . The shaped, bone fiber-based product of claim 32 , wherein the product is at least about 90% as intact when rehydrated as before dehydration.
37 . The shaped, bone fiber-based product of claim 32 , wherein the product when rehydrated remains greater than about 90% intact after being bent, compressed, twisted, squeezed, and/or rolled.
38 . The shaped, bone fiber-based product of claim 32 , wherein the product is not a putty when rehydrated.
39 . The shaped, bone fiber-based product of claim 32 , wherein the bone fibers comprise at least one growth factor selected from the group consisting of IGF-1, BMP-2, BMP-4, BMP-7, and combinations thereof.
40 . The shaped, bone fiber-based product of claim 39 , wherein the at least one growth factor is native.
41 . The shaped, bone fiber-based product of claim 39 , wherein the at least one growth factor is selected from the group consisting of IGF-1 in an amount greater than 60 pg per gram of demineralized bone matrix, BMP-2 in an amount greater than 2700 μg per gram of demineralized bone matrix, BMP-4 in an amount greater than 200 μg per gram of demineralized bone matrix, BMP-7 in an amount greater than 9000 μg per gram of demineralized bone matrix, and combinations thereof.
