Abstract
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.
Claims13
An implant suitable for being anchored with the aid of mechanical vibration in an opening in bone tissue or other hard tissue, the implant defining an axis and the implant further comprising a coupling-in face for applying a compressing force and the mechanical vibration, said coupling-in face being not parallel to the axis,
- the implant comprising at least two implant components, the implant components being configured and arranged to be pressed against each other along a common contact interface when a compressing force acts on the implant along the axis and to thereby undergo a relative shifting movement along the common contact interface,
- wherein the implant further comprises a thermoplastic material forming at least a part of a peripheral surface portion,
- and wherein the compressing force applied along the axis causes an enlargement of a distance between the peripheral surface portion of the implant and the compression axis when the thermoplastic material is in a solid state.
An implant suitable for being anchored with the aid of mechanical vibrations in an opening in bone tissue or other hard tissue, the implant extending along an axis between a proximal end face and a distal end face, wherein the implant comprises a plurality of components, one of the components comprising the proximal end face and another one of the components comprising the distal end face, wherein a peripheral surface portion of the implant comprises a thermoplastic material, wherein the components are configured and arranged relative to one another so that when the implant is compressed by a compressing force between the proximal and distal end faces while the thermoplastic material is in a solid state, the peripheral, surface portion is pressed outwardly away from the axis, whereby the implant is capable of being anchored in the opening in the bone tissue or other hard tissue by applying the compressing force and by coupling mechanical vibration into the implant via the proximal end face or the distal end face or both, and by thereby pressing the peripheral surface portion against a lateral wall of the opening and at least partially liquefying the thermoplastic material where in contact with the lateral wall and pressing the liquefied thermoplastic material into structures of the bone tissue or other hard tissue to form, after re-solidification, a positive fit connection with the lateral walls.
