Definitions

  • the invention relates to a bone implant with an implant body, which has a screw thread on its periphery for screwing the implant body into the human bone and the surface of which is equipped with a biocompatible structure.
  • Bone implants with helical implant bodies are known which are screwed into a correspondingly dimensioned hole in human bone.
  • the hole is dimensioned according to the core diameter of the screw thread, so that when the implant is screwed in, it is securely anchored in the bone. Screwing in is made easier if the screw thread is self-tapping. For this purpose, cutting edges are incorporated into the screw thread, so that it acts like a tap.
  • Such implants can preferably be designed as jaw implants (e.g. EP 1 234 550 AI).
  • Bone implants usually consist of a material that is well tolerated by the tissue of human bone. Titanium is particularly suitable and titanium alloys or tantalum and tantalum alloys. In order to promote rapid and permanent ingrowth of the implant in the bone, the known implants in the surface areas that come into contact with bone tissue are provided with a surface roughness which improves the attachment of the bone cells to the implant surface. A jaw implant with different surface roughness along its circumference is disclosed in US Patent 5,989,027. A central part of the implant, which is made of titanium, is provided with a porous metal layer, which is produced by sintering on a powder of titanium or a titanium alloy.
  • Adjacent to this part is an area in which the implant has a lower roughness and which is produced by sandblasting the titanium surface. This area is followed by a further area which is essentially smooth and in which the biocompatible properties of the titanium come into effect.
  • the implant can be designed as a screw, in which the part of the implant surface provided with the porous metal layer is located above the thread or is superimposed on the thread.
  • the invention proposes a screw-in bone implant that has increased biocompatibility through improved adaptation of the implant surface to the structure of the bone tissue.
  • the screw thread on the circumference of the implant has a number of groove-shaped depressions, the size of which corresponds to the size of the osteons of the bone tissue which attach to the groove-shaped depressions.
  • the groove-shaped depressions preferably run in a direction which corresponds essentially to the direction of the threads of the screw thread.
  • the groove-shaped depressions only extend over part of a circumferential line, and a plurality of groove-shaped depressions are arranged one behind the other along the same circumferential line and have a variable width and depth over their length.
  • the groove-shaped depressions form a micro thread superimposed on the screw thread, which does not hinder the screwing-in process and increases the contact area between the implant and the bone tissue. Due to the groove-shaped depressions, the bone tissue is preformed when the implant is screwed in, which prepares its attachment to the implant body. The adjustment of the groove size to the size of the osteons favors the attachment of the osteons to the implant surface. The osteons align themselves with the groove-shaped depressions and attach themselves to the implant surface along these depressions.
  • the implant has a self-tapping thread, in which the groove-shaped depressions extend over the threads that are interrupted by the cutting edges.
  • FIG. 1 shows a side view of a jaw implant designed according to the invention
  • Figure 2 is an enlarged partial view of the profile of a jaw implant designed according to the invention

Abstract

L'invention concerne un implant osseux (10) comportant un filet de vis (11) au niveau de sa périphérie, afin de visser ledit implant dans l'os concerné, qui présente des cavités sous forme de canules (16), situées dans le filet de vis. Les cavités sous forme de canules (16) correspondent, dans leur dimension, à la dimension des ostéones du tissus osseux, qui se déposent sur les cavités sous forme de canules. Ces dernières s'étendent de préférence dans une direction, correspondant sensiblement au sens des pas (15) du filet de vis. Elles forment un microfilet superposé au filet de vis, qui augmente la surface de contact entre l'implant et le tissu osseux. L'adaptation de la dimension des canules à celle des ostéones favorise le dépôt desdits ostéones sur la surface de l'implant.
