Zusammenfassung
Im Bereich der regenerativen Zahnheilkunde, in der dentalen Implantologie und bei größeren Knochendefiziten im Mund-, Kiefer- und Gesichtsbereich werden routinemäßig Knochenersatzmaterialien (KEM) eingesetzt (Sinuslift, horizonale und vertikale Knochendefekte). KEM müssen strukturelle, physikalische und biologische Eigenschaften des jeweiligen Knochenlagers imitieren. Biokompatibilität und biologische Abbaubarkeit sind wichtig für die vaskuläre und knöcherne Erschließung und für die funktionelle Einheilung. KEM müssen mit direkt benachbarten Gewebestrukturen (Knochen) bzw. Zellpopulationen interagieren, d. h. Knochengewebe wächst entlang den Leitstrukturen des KEM (Osseokonduktion) ein, Porenstrukturen ermöglichen den Transfer von Nährstoffen und Zytokinen. Lokale Infekte und Pathologien stellen eine Kontraindikation für eine knöcherne Augmentation dar. Ein intaktes und ausreichend dimensionertes weichgewebliches Lager ist eine unabdingbare Voraussetzung für eine erfolgreiche knöcherne Augmentation.
