Abstract

The implant is provided with a scaly surface on which the position of individual scale formations in adjacent rows is staggered, while their orientation direction alternates.

Description

Problematikproblem

Seit über 50 Jahren wird Titan für die Herstellung der Implantate verwendet. Die Herstellerfirmen bemühen sich in den letzten Jahren um besondere Gestaltung des Designs und Verbesserungen in der Bearbeitung der Oberfläche mit unterschiedlichen Techniken und Verfahren, um eine bessere Integration des Implantats im Kieferknochen zu erreichen.Titanium has been used in the manufacture of implants for over 50 years. The Manufacturers have been trying to design the Designs and improvements in the processing of the surface with different Techniques and procedures to ensure better integration of the implant in the To reach jawbones.

Trotz des bisher Erreichten werden immer wieder Implantate abgestoßen. Die Gründe hierfür können vielfältig sein, häufig ist aber letztlich der Auslöser der Abstoßung eine Perimplantitis (Entzündung des Implantatumfeldes). Perimplantitis wird vom Implantat selbst verursacht und tritt selbst bei Titan-Implantaten auf, die nach derzeitigem Kenntnisstand als biologisch verträglich gelten.Despite what has been achieved so far, implants are repeatedly rejected. The reasons there can be many different ways of doing this, but ultimately the trigger of the rejection is ultimately one Perimplantitis (inflammation of the implant area). Perimplantitis is caused by the implant itself causes and occurs even with titanium implants, which after the current State of knowledge as biologically compatible.

Dieser Sachverhalt legt nahe, dass die Entstehung von Perimplantitis und die daraus resultierende Abstoßung des Implantats folgende Ursachen haben könnte:
This fact suggests that the development of perimplantitis and the resulting rejection of the implant could have the following causes:

  • - Biologische Unverträglichkeit des Materials- Biological incompatibility of the material
  • - Abstoßungsreaktion des Knochengewebes gegen Fremdkörper aufgrund von mechanischen Eigenschaften von Metall-Implantaten (Oberflächenhärte, mangelnde Elastizität) bzw. der bei der Oberflächenbearbeitung eingesetzten Techniken (z. B. Ätzung)- Bone tissue rejection reaction against foreign bodies due to mechanical properties of metal implants (surface hardness, lack of elasticity) or the one used in surface processing Techniques (e.g. etching)
  • - Interaktionsspannung mit anderen Materialien der prothetischen Versorgung- Interactional tension with other prosthetic restoration materials
Beschreibung der ErfindungDescription of the invention

Aus diesen und anderen Gründen entstand zunächst die Überlegung, dass ein Implantat aus dem thermoplastischen Material promysan® STAR das Risiko der Abstoßung deutlich verringern könnte. Diese Überlegung beruht auf den folgenden Punkten:
For these and other reasons, the first consideration was that an implant made of the thermoplastic material promysan® STAR could significantly reduce the risk of rejection. This consideration is based on the following points:

  • - Die bereits gesammelten Erfahrungen aus der prothetischen Versorgung zeigen, dass die biologische Verträglichkeit deutlich besser ist als bei Metallen selbst bei Titan. (Der Kunststoff ist u. a. nicht radioopak.)- The experience already gained from prosthetic restoration show that the biological compatibility is significantly better than with metals even at Titan. (Among other things, the plastic is not radio-opaque.)
  • - Die mechanischen Eigenschaften des Kunststoffs sind denen von Knochen u. a. hinsichtlich Biegefestigkeit und Oberflächenhärte sehr ähnlich. Dadurch bieten sie der Microbewegung des Knochens keinen Widerstand. Die gute Formstabilität (Formgedächtnis) wirkt sich zusätzlich positiv aus.- The mechanical properties of the plastic are those of bones u. a. very similar in terms of bending strength and surface hardness. Thereby they offer no resistance to the micro-movement of the bone. The good Shape stability (shape memory) also has a positive effect.
  • - Die Oberfläche verändert sich anders als z. B. bei anderen Kunststoffen im Zeitablauf nicht, wodurch v. a. Infektionsherde vermieden werden.- The surface changes differently than e.g. B. with other plastics in No lapse of time, whereby v. a. Foci of infection can be avoided.
  • - Interaktionsspannungen mit Metallgerüsten (z. B. aus Goldlegierungen, Titan oder Cr-Ko-Mo Legierungen) oder anderen Kunststoffen in der prothetischen Versorgung entstehen nicht.- Interaction stresses with metal frameworks (e.g. made of gold alloys, titanium or Cr-Ko-Mo alloys) or other plastics in the prosthetic Supply does not arise.

Die Verwendung des alternativen Materials promysan® STAR schafft die Voraussetzung für die vorliegende Erfindung, stellt jedoch nur einen Teilaspekt in der Lösung der Abstoßungs-Problematik bei Implantaten dar.The use of the alternative material promysan® STAR creates that Prerequisite for the present invention, however, is only a partial aspect in the Solution of the rejection problem with implants.

Wesentlich ist die besondere Gestaltung der Oberfläche des Implantats, die für die mechanische Verbindung mit dem Knochengewebe Ausschlag gebend ist. Die innovative schuppenartige Gestaltung der Oberfläche mit versetzter und alternativ gegenläufiger Anordnung der Schuppen (Fig. 1) bietet die folgenden Vorteile:
What is essential is the special design of the surface of the implant, which is crucial for the mechanical connection to the bone tissue. The innovative scale-like design of the surface with staggered and alternatively opposing arrangement of the scales ( Fig. 1) offers the following advantages:

  • - Die Schuppen wirken bereits kurze Zeit nach dem Einsetzen des Implantates stark retentiv.- The scales work shortly after the implant is inserted strongly retentive.
  • - Die Oberfläche des Implantates ist erheblich vergrößert, was die langfristige mechanische Verbindung mit dem Knochen begünstigt.- The surface of the implant is significantly enlarged, which is the long-term mechanical connection with the bone favors.
  • - Die Oberflächengestaltung fördert die Durchblutung der Kapilargefäße des Knochens beim Kauvorgang (Kaubelastung) und verbessert somit Zellernährung und -regeneration bzw. -erneuerung.- The surface design promotes blood flow to the capillary vessels of the Bones during the chewing process (chewing load) and thus improves Cell nutrition and regeneration or renewal.

Aufgrund der oben dargelegten Beschreibung der Erfindung ergeben sich die im Folgenden aufgeführten Patentansprüche.Based on the description of the invention set out above, the result in The following claims.
