3D Druck – Schicht für Schicht zum fertigen Implantat
Die additive Fertigung im 3D-Druck-Verfahren beschreibt einen Herstellungsprozess, bei dem mithilfe eines Lasers und eines pulverförmigen Werkstoffs, Schicht für Schicht eine nahezu beliebige, dreidimensionale Geometrie erzeugt werden kann.
Neben vielen anderen Anwendungsgebieten nimmt die Bedeutung dieses Fertigungsprozesses auch im Bereich der Implantatherstellung zu. Erst der 3D-Druck ermöglicht die Fertigung von AESCULAP® Structan® - einer porösen, homogenen Gitterstruktur, die das knöcherne Anwachsen und Durchbauen fördern soll.
Auch das knochenähnliche Elastizitätsmodul und die hohe Druckfestigkeit von Structan® tragen zu einer knöchernen Integration in die Wirbelsäule bei. Die AESCULAP® 3D Implantate wurden hierbei mit dem Ziel entwickelt, ausreichend Stabilität zu bieten, ohne dabei in die angrenzenden Wirbelkörper einzubrechen.
Auch die intra- und postoperative Bildgebung profitiert von der gitterartigen Structan® Struktur. So sind die Implantate einerseits intraoperativ gut auf dem Röntgenbild zu erkennen, behindern aber gleichzeitig bei späteren Nachkontrollen nicht die Sicht auf die umliegende Knochenbildung.
Mit den AESCULAP® 3D Cages kombinieren wir unsere jahrzehntelange Erfahrung im Bereich der Entwicklung und Herstellung von Implantaten mit der neusten Fertigungstechnologie.
