Implant

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.

1 . 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 wherein the implant comprises a deformation zone.  
   
   
       2 . An implant according to  claim 1 , wherein the spacer comprises the deformation zone.  
   
   
       3 . An implant according to  claim 2 , wherein the deformation zone is provided on one or both sides of each non-rotational means.  
   
   
       4 . An implant according to  claim 1 , wherein the deformation zone comprises an (internal) acute angle.  
   
   
       5 . An implant according to  claim 1 , wherein the internal connection posts are adapted to avoid excessive bending.  
   
   
       6 . An implant according to  claim 1 , wherein the implant connection and/or the internal abutment connection is adapted to undergo metal deformation.  
   
   
       7 . An implant according to  claim 1 , wherein the corners of the connection posts or elements are deformed in order to minimize rotational movements.  
   
   
       8 . An implant according to  claim 1 , wherein it is the corners of the guidance portion that are deformed.
