A resorbable three-dimensional tissue scaffold comprising bioactive glassfibers;bioactive glass bonding to at least a portion of the bioactive glass fibers;and pore spacewithin the three-dimensional tissue scaffold predetermined by volatilecomponentsremoved during the bioactive glass bonding to the bioactive glass fibers,wherein the pore space creates a porosity between about 40% and about 85% intheresorbable three-dimensional tissue scaffold. The resorbable tissue scaffoldsupportstissue in-growth to provide osteoconductivity as a resorbable tissue scaffold,used forthe repair of damaged and/or diseased bone tissue.
