International ClassesC08K 003/32C08L 023/00 AbstractComposites suitable for use as prostheses for attachment to soft tissues, such as cartilage, tendons, skin, tympanic membrane and gingiva, as well as to cancellous or trabecular bone, are based on combination of a polyolefinic binder with certain bioactive glass materials. The composites bond actively with soft tissues and are readily formulated achieve mechanical properties comparable to those of the soft tissue of interest.Field of SearchAlkali or alkali earth silicateMaterial contains glass Inorganic NRM additive Phosphorus atom DNRM Organic NRM additive Composition suitable for use as tissue or body member replacement, restorative, or implant Composition which anchors by ingrowth of surrounding tissue Composition suitable for use as tooth or bone replacement, restorative, or implant Implant or insert | |
