Seit Herbst 2016 ist zirkonoxidverstärktes Lithiumsilikat (ZLS) als Celtra Press von Dentsply Sirona Prosthetics erhältlich – und hat mit einer Drei-Punkt-Biegefestigkeit von über 500 MPa die Messlatte für hochfeste Glaskeramiken noch einmal deutlich höher gelegt. Nun zeigen Untersuchungen der Universität Gießen: Auch in der Biaxialfestigkeit liegt Celtra Press im Feld der Wettbewerber klar vorn (Abb. 1).
Messungen der Drei-Punkt-Biegefestigkeit haben für Celtra Press einen Wert von 567 MPa ergeben1. Zum Vergleich: Das schleifbare ZLS Celtra Duo (ebenfalls von Dentsply Sirona) kommt auf 210 MPa nach Schleifen und Polieren und nach einem optionalen Glasurbrand auf 370 MPa1.
