Die Erfindung betrifft ein Befestigungselement, insbesondere zur Befestigung von Membranen aus bioresorbierbaren Polymeren bei der gesteuerten Knochenregeneration. The invention relates to a fastening element, in particular for fastening membranes made of bioresorbable polymers during controlled bone regeneration.

Zahnverluste, durch parodontale Erkrankungen oder Entfernung eines nicht erhaltungswürdigen Zahnes, gehen häufig mit Atrophien des Knochens einher. Das verminderte Knochenangebot schließt die Einbringung von Implantaten aus, wenn der Erfolg der Knochenregeneration in Frage gestellt ist.Tooth loss, due to periodontal disease or the removal of a tooth that is not worth preserving, is often accompanied by bone atrophy. The reduced bone supply precludes the insertion of implants if the success of bone regeneration is in question.

genannten gesteuerten Knochenregeneration aus dem Defekt isoliert werden. Dies gelingt durch eine Membran aus einem bioresorbierbaren Polymer, die während der Knochenregeneration als Barriere das Einwachsen der schnell proliferierenden Zellen verhindert und anschließend vom Körper resorbiert wird. Unter dem Schutz dieser Membran kann somit eine knöcherne Ausheilung von periimplantären Defekten erfolgen.so-called controlled bone regeneration. This is achieved by a membrane made of a bioresorbable polymer, which acts as a barrier during bone regeneration to prevent the ingrowth of rapidly proliferating cells and is then reabsorbed by the body. Under the protection of this membrane, bone healing of peri-implant defects can take place.
Der Erfindung liegt die Aufgabe zugrunde, ein Befestigungselement zum Fixieren von Membranen für die gesteuerte Knochenregeneration am jeweiligen Implantationsort zu schaffen.The invention is based on the object of creating a fastening element for fixing membranes for controlled bone regeneration at the respective implantation site.
Erfindungsgemäß gelingt die Lösung der Aufgabe dadurch, daß das Befestigungselement aus einem resorbierbaren Polymer besteht und einen zylindrischen Körper aufweist, an dessen einem Ende eine Spitze und an dessen anderem Ende ein Kopf angebracht ist. Mit der Erfindung ist, ein Befestigungselement aus einem ebenfalls resorbierbaren Kunststoff (PoIy-(L-lactid-co-DjL-lactid) 70/30) geschaffen worden. Die Gestaltung des Pins ermöglicht ein schnelles und einfaches Applizieren sowie eine dauerhafte Lagesicherung der Folie, während der gesamten Funktionszeit der Folie.According to the invention, the problem is solved in that the fastening element consists of a resorbable polymer and has a cylindrical body, at one end of which a tip is attached and at the other end a head. The invention creates a fastening element made of a plastic that is also resorbable (poly(L-lactide-co-DjL-lactide) 70/30). The design of the pin enables quick and easy application and permanent securing of the position of the film during the entire service life of the film.
Ferner ist es möglich, daß der zylindrische Körper mit Retensionsrillen versehen ist, um einen sicheren Halt des Befestigungselementes zu gewährleisten. Furthermore, it is possible for the cylindrical body to be provided with retention grooves to ensure a secure hold of the fastening element.

Des weiteren ist es möglich, daß der Kopf des zylindrischen Körpers linsenförmig ausgebildet ist. Dadurch wird die sichere Befestigung der Membran erreicht, ohne daß das Befestigungselement am Implantantionsort als störend empfunden wird.Furthermore, it is possible for the head of the cylindrical body to be lens-shaped. This ensures that the membrane is securely attached without the fastening element being perceived as disturbing at the implantation site.
Eine vorteilhafte Ausführungsform des erfindungsgemäßen Befestigungselementes sieht vor, daß der Schaftdurchmesser ca. 0,8 mm und der Kopfdurchmesser ca. 2,5 mm beträgt.An advantageous embodiment of the fastening element according to the invention provides that the shaft diameter is approximately 0.8 mm and the head diameter is approximately 2.5 mm.
Eine zweckmäßige Ausführung sieht vor, daß das Befestigungselement aus Poly-(L-lactid-co-D, L-Lactid) besteht. Dieses Material gewährleistet eine gute Verträglichkeit beim Resorbieren des Befestigungselementes. A practical design provides that the fastening element is made of poly-(L-lactide-co-D, L-lactide). This material ensures good compatibility when the fastening element is resorbed.
Die Erfindung wird im folgenden anhand eines Ausführungsbeipieles näher erläutert. In der zugehörigen Zeichnung zeigt:The invention is explained in more detail below using an example embodiment. The accompanying drawing shows:

Das in der Zeichnung dargestellte Befestigungselement wurde in Form eines Pins realisiert. Wie aus der Figur ersichtlich ist, besteht es aus einem mit Retentionsrillen versehenen Schaft, der an einem Ende eine Spitze und am anderem Ende einen linsenförmig abgeflachten Kopf aufweist. Ein Pindurchmesser von 0,8 mm erlaubt die Verwendung des gängigen AO-Instrumentariums zum Anbringen der Bohrungen. Appliziert werden die Befestigungselemente mittels eines Eindrückinstrumentariums mit Haltevorrichtung. The fastening element shown in the drawing was made in the form of a pin. As can be seen from the figure, it consists of a shaft with retention grooves, which has a point at one end and a lens-shaped flattened head at the other end. A pin diameter of 0.8 mm allows the use of standard AO instruments to create the holes. The fastening elements are applied using an insertion instrument with a holding device.
