CLINICAL GUIDE III SCIENTIFIC COMPENDIUM

ZOLID ZIRCONIA – MUCH MORE THAN JUST A WHITE DISC With Zolid, Amann Girrbach provides a comprehensive all-ceramic system for high-quality and esthetic zirconia restorations. Complete integration into the CAD/CAM workflow ensures maximum process reliability and continuously high quality. This material is backed by a decade of experience in the development and in-house production of zirconia for restorations. Amann Girrbach laid the foundation stone 10 years ago with the Ceramill ZI blanks for copy milling. Since then, more than 10 million units have been produced from Amann Girrbach zirconia blanks...

ZOLID ZIRCONIA – DENTAL DREAMS ARE MADE OF THIS Zirconia (ZrO2) forms the ideal basis for all-ceramic restorations as this material has outstanding properties that can hardly be matched by any other material. MECHANICAL PROPERTIES OPTICAL PROPERTIES Compared to other ceramic materials, ZrO2 is the absolute leader in terms of mechanical properties. Its strength of up to 1,200 MPa is significantly higher than that of commercially available lithium disilicate (500 MPa) or feldspar ceramics (160 MPa). Furthermore, zirconia also offers excellent fracture toughness and excellent ageing resistance....

STUDIES The chapter “Studies” of the Scientific Compendium shows the current status of the most important external studies, which underline the clinical evidence of Zolid products. The results of the studies reflect the excellent properties of the blanks from Amann Girrbach and provide additional scientific certainty.

IN VITRO MECHANICAL/OPTICAL PROPERTIES SUMMARY AND CONCLUSION The monolithic zirconium oxides achieved lower contrast values than conventional zirconium oxide. No correlation between the contrast values and the grain size could be observed. The flexural strengths determined (see Fig. 1) show that the monolithic zirconium oxides have lower flexural strengths than conventional zirconium oxide. The ageing of the materials has no significant influence on the flexural strength. For Ceramill Zolid, the flexural strength increases after hydrothermal ageing and demonstrates the highest flexural strengths...
