Implant, implantation device, implantation method

摘要

An implant suitable for being anchored with the aid of mechanical vibration in an opening provided in bone tissue. The implant is compressible in the direction of a compression axis under local enlargement of a distance between a peripheral implant surface and the compression axis. The implant includes a coupling-in face which serves for coupling a compressing force and the mechanical vibrations into the implant, which coupling-in face is not parallel to the compression axis. The implant also includes a thermoplastic material which, in areas of the local distance enlargement, forms at least a part of the peripheral surface of the implant.

主权项

1. A method of anchoring an implant in hard tissue or hard tissue replacement material, the method comprising the steps of:
providing an opening in the hard tissue or hard tissue replacement material; providing the implant, the implant being compressible in the direction of a compression axis under local enlargement of a distance between a peripheral surface of the implant and the compression axis, wherein the implant comprises a coupling-in face not parallel to the compression axis for the coupling-in of a compressing force and mechanical vibration, and wherein the implant further comprises a thermoplastic material forming at least a part of the peripheral implant surface in areas of the local distance enlargement, positioning the implant in the opening such that the thermoplastic material of the implant is in contact with the hard tissue or hard tissue replacement material when the compressing force is coupled into the implant; coupling the compressing force and the mechanical vibrations via the coupling-in face into the positioned implant, whereby the implant is compressed and due to the distance enlargement at least locally pressed against lateral walls of the opening and the thermoplastic material, as a result of being pressed against the lateral walls, is at least partly liquefied where in contact with the lateral walls and pressed into structures of the hard tissue or hard tissue replacement material to form, after re-solidification, a form-fit connection with the lateral walls.
