Abstract
The present invention is directed to a threaded implant intended to be screwed into bone, preferably into jawbone, and for tightly fitting a prosthesis, including a spacer portion in the screwed-in position. The implant body has an internal connection arrangement for rotationally locking said spacer, said arrangement also cooperating during positioning and insertion of the implant body with a tool and said arrangement having a low vertical height.
Claims53
An implant for a tightly fitting prosthesis, said implant comprising:
- an externally threaded implant body intended to be screwed into bone using an insertion tool, the body being provided with an internal open ended axial bore and an indexing region at the open end of the bore, the indexing region being provided with a connection to support a spacer element and having means for co-operating with the spacer element to prevent twisting between the spacer element, the implant body and the insertion tool characterised in that that the axial length of the indexing region does not substantially overlap with the external thread.
An implant for a tightly fitting prosthesis, said implant comprising an externally threaded implant body intended to be screwed into bone using an insertion tool, the body being provided with an internal open ended axial bore and an indexing region at the open end of the bore, the indexing region being provided with a connection to support a spacer element and having means for co-operating with the spacer element to prevent twisting between the spacer element, the implant body and the insertion tool characterised in that that the implant comprises a deformation zone.
An implant for a tightly fitting prosthesis, said implant comprising an externally threaded implant body intended to be screwed into bone using an insertion tool, the body being provided with an internal open ended axial bore and an indexing region at the open end of the bore, the indexing region being provided with a connection to support a spacer element and having means for co-operating with the spacer element to prevent twisting between the spacer element the implant body and the insertion tool characterised in that that the implant comprises a deformation zone.
An arrangement for a threaded implant adapted to permit application of a screwing force for positioning and securing, in the implant's screwed-in position, the implant comprising an open ended internal bore;
- at least one spacer element against a contact surface of the implant, wherein the implant is provided an indexing region with means for preventing and twisting which can be assigned to both the tool and the spacer element or the tool and the indexing region, characterised in that the axial length of the indexing region does not extend deeper into the bore and does not overlap of the external thread.
A method for anchoring a threaded implant in a bone and applying at least one spacer element to a contact surface if the implant in its screwed-in position, characterised in that the screwing-in is effected by means of a tool which is arranged on a twisting preventing portion provided in the implant and in that this portion also provides a twisting prevention for the spacer element during at least the clinical function.
An implant or an arrangement substantially as described with reference to the accompanying drawings.
