Abstract: A multiple component material, in particular a filler particle containing implantation material is produced and used to anchor prothesis components in bones, to strengthen bones, as dowel for bone screws and as implants for anchoring screws. The polymer component of the disclosed implantation material is preferably based on an acrylate or polymethacrylate basis, or on an acrylate and methacrylate copolymer or a mixture thereof. The polymer component encloses the filler particles at least in part. Preferably, the filler particles are 5 to 15 .mu.m in size and have at least 50% void volume. The multiple component material is stored in a dry, stable particulate form ready for use by mixing with monomer liquid.
