    摘要: A tissue scaffold fabricated from bioinert fiber forms a rigid three-dimensional porous matrix having a bioinert composition. Porosity in the form of interconnected pore space is provided by the space between the bioinert fiber in the porous matrix. Strength of the porous matrix is provided by bioinert fiber fused and bonded into the rigid three-dimensional matrix having a specific pore size and pore size distribution. The tissue scaffold supports tissue in-growth to provide osteoconductivity as a tissue scaffold used for the repair of damaged and/or diseased bone tissue.

    摘要: The present disclosure relates to a dynamic bioactive bone graft material and a method of handling the material to prepare an implant. In one embodiment, a method of preparing a dynamic bioactive bone graft implant is provided. The method includes the step of providing a porous, fibrous composition of bioactive glass fibers, wherein the fibers are characterized by fiber diameters ranging from about 5 nanometers to about 100 micrometers, and wherein the porosity of the matrix ranges from about 100 nanometers to about 1 millimeter. The porous, fibrous composition is introduced into a mold tray, and a shaped implant is created using the mold tray. The composition may be wetted with a fluid such as saline or a naturally occurring body fluid like blood prior to creating the shaped implant. In another embodiment, the porous, fibrous composition is provided with the mold tray as a kit.
