Abstract: The invention relates to an artificial joint system which, by a combination of defined pretension in the implant in the resection plane and a wholly or partially resorbable shaft or clamping system connects, after a transition period after implantation, the intermediate member of the implant with the remaining bone in the resection plane and the shaft required in the long bone during the transition period decomposes at the surface or the clamping system of the intermediate member deomposes to such an extent that unphysiological force transmission into the bone through the shaft of the implant or through the clamping system is no longer possible.

Abstract: In order to extend durability and long-term use of bone, joint and tooth root implants, the previously limited-time implants are replaced by metallic or composite fiber implants for bone and tooth root replacement having a partially or completely resorbable matrix on the side of the bone. On the side of the bone, the matrix is composed of organic and/or inorganic materials which are resorbed after the implantation and are replaced by natural bone. This produces a bond free of connective tissue between the bone and the remaining structure, assuring a physical friction fit. The remaining structure is firmly bonded to the core of the implant.
