Claim Text:
1. An implant system to be fastened to human or animal bone tissue, the system comprising: an implant comprising a bone side to be brought into contact with the bone tissue, the bone side of the implant being equipped with a plurality of fastening structures restricted to said bone side; and a plurality of fasteners, each with a distal side and a proximal side, wherein the distal side is equipped for anchoring the fastener in the bone tissue and the proximal side is equipped for a connection with the fastening structures of the implant so that the proximal side of the fastener does not reach to a side of the implant facing away from the bone side, wherein at least one of the following conditions holds: one of the fastening structures and of the proximal sides of the fasteners comprises undercut recesses and the other one of the fastening structures and of the proximal sides of the fasteners comprises protrusions which are insertable or snappable into the undercut recesses; one of the fastening structures and of the proximal sides of the fasteners comprises undercut recesses and the other one of the fastening structures and of the proximal sides of the fasteners comprises a thermoplastic material embeddable in the undercut recesses when melted or at least softened; one of the fastening structures and the proximal sides of the fasteners comprises conical protrusions and the other one of the fastening structures and the proximal sides of the fasteners comprises conical recesses, wherein pressing the conical protrusions into the conical recesses results in a press fit connection; the fastening structures and the proximal sides of the fasteners comprise thermoplastic material capable of making a material connection, wherein on a side of the implant different from the bone side an axis of application of energy for liquefying the thermoplastic material is defined, and wherein said axis of application of energy is not parallel to an axis of at least one of the fasteners; wherein the distal sides of the fasteners are equipped with a material which is liquefiable by mechanical oscillation for being anchored with the aid of mechanical oscillation.
