Zusammenfassung

In der modernen Zahnmedizin bieten sich Keramikimplantate als Pfeiler für implantatgetragene Restaurationen an. Auch Patienten interessieren sich immer häufiger für metallfreie Versorgungen – sowohl bei der prothetischen Restauration („Was kommt auf mein Implantat?“) als auch bei der Wahl des Materials („Woraus besteht mein Implantat?“). Für den Behandler stellt sich daher die Frage: „Kann ich keramische Implantate bedenkenlos anbieten?“

Abstract

In modern dentistry, there is a great interest in metal-free restorations; this also applies to ceramic implants. Many ceramic implant systems are already available on the dental market – some without scientific validation. More preclinical and clinical (long-term) data is urgently needed to prove the safety and reliability of the systems. Particularly for two-part implants and extended indications there are currently no reliable data available. Ceramic implants today consist of various modifications of ZrO₂. New zirconia-based dispersion ceramics, metal-free and screw-retained implant-abutment connections as well as more favorable manufacturing processes represent future development trends. The osseointegration of ZrO₂ implants and titanium implants is comparable. The optimal roughness and the optimal surface treatment of ceramic implants are still discussed controversially. ZrO₂ seems to be “soft tissue friendly”. The survival rate of ZrO₂ implants is more than 95% after 12 months.
