  • the invention also relates to a method for producing external layer arrangements on one or more outer surfaces of an implant with attachment and hole-insert parts.

  • the oxide layer has a thickness in the range of from 5 nm to 20 ⁇ m.
  • the oxide layer can in this case have a thickness varying along the longitudinal and/or circumferential direction (s) of the implant.
  • a layer of calcium phosphate can be applied on top of the oxide layer.
  • a method according to the invention is characterized in that the implant is machined and/or treated to produce a high roughness value or a preferably high porosity on the surface or surfaces, and in that said surface or surfaces are thereafter - 3 - coated with an oxide layer.
  • the oxide layer can be obtained with the aid of electrochemical treatment in which the surface or surfaces of the implant are dipped in an electrolyte, in which an anode and cathode arrangement is provided.
  • a voltage is applied to the anode and cathode arrangement, and a current produced by the voltage is led via the electrolyte and the implant dipped in the latter.
  • a high porosity can be obtained if the voltage assumes a relatively high value, for example a value of 300 volts or more, and a certain type of electrolyte is used.
  • the oxide layer can be applied in a similar manner, the implant being dipped in the same electrolyte or in another electrolyte, and the voltage value being chosen at a lower level so that the oxide layer is established with a lower degree of porosity or a porosity which is almost zero.
  • Such a smoother oxide layer can also be produced by heat treatment of the implant in an oxygen-containing atmosphere.
  • the method proposed above makes it possible to produce a range of implants with different porosities, porosity extents, treated surfaces, etc. From this range it is possible to choose the implant which is best suited for the treatment situation in question.
  • the quality of the bone in question for example jaw bone or tooth bone, varies greatly in the same individual and between different individuals.
  • the bone structure of the upper jaw is relatively soft, whereas the bone structure of the lower jaw can vary from a relatively soft structure to a hard structure at the front of the jaw. Implants of greater or lesser porosity can thus be produced and, similarly, oxide layers with a fine surface structure can be applied on top of the already existing surface with a high roughness value or porosity.
  • the smoother surface can also constitute a substrate surface for layers having bone- growth agents or bone-growth-promoting agents.
  • the oxide layer applied on top of the uneven or porous surface can consist of a thin or relatively thick oxide layer which can be applied in a known manner by simple dipping in a voltage-connected electrolyte in a manner known per se .
  • the form and thickness of the oxide layer can be varied.
  • the oxide layer can have a greater thickness at the central or outer parts of the implant.
  • the oxide layer can be applied here and there on the porous outer surface in question.

  • Figure 3 is a diagram showing voltages and currents which arise in an electrochemical method on an implant dipped in an electrolyte
  • Figure 4 is a vertical section and schematic representation showing the implant according to Figure 1 dipped in an electrolyte, and an anode and cathode arrangement provided in the latter.
  • the implant has an attachment part 2, for example for a spacer element, and a hole-insert part 3.
  • the outer surface 2a of the attachment part can be smooth or precision-worked (for example machined) or can have a greater or lesser porosity.
  • the hole- insert part 3 can have a cylindrical portion with outer thread 3a, and a conical portion with outer thread 3b at the free/lower end of the implant.
  • the implant is of the so-called self- tapping type and can be screwed into a hole 4 in a bone, for example a tooth bone or jaw bone.

Abstract

L'invention concerne un implant (1) comprenant une fixation et des parties d'introduction (2, 3) dans un alésage dotées d'au moins une surface extérieure possédant des agencements de couche extérieure (6, 7). Cet implant peut être placé de manière connue, des filetages (3a, 3b) étant réalisés sur des parties cylindrique et conique. Il est généralement réalisé en deux étapes de production. Selon une première étape de production, la surface extérieure (6a) de l'implant présente une valeur de rugosité et/ou un degré de porosité relativement élevés. Selon une seconde étape, la surface irrégulière et poreuse ainsi obtenue est recouverte d'une couche d'oxyde (7) pouvant être uniforme ou d'épaisseur différente dans les sens longitudinal et/ou circulaire de l'implant. Selon un mode de réalisation, une couche d'oxyde (7) peut être recouverte d'un agent de croissance ou de promotion osseuse et/ou de phosphate de calcium (16), par exemple par dépôt, immersion, ou vaporisation chimiques.
