CELTRA - a High-Strength Glass-Ceramic with Diverse Application Options
Rinke, Sven
All-ceramic restorations are today an integral part in the restorative treatment concept. The clinically secured indications range from all-ceramic inlays to partial crowns and veneers, single crowns or bridges in the anterior and posterior regions. All-ceramic materials can also be used for the fabrication of custom abutments. These diverse application options require the use of different materials optimised according to the respective indication. It is important in these cases always to combine adequately high strength with indication-appropriate translucency. A new material (Dentsply / DeguDent) that meets these requirements in a very particular way is zirconia-reinforced lithium silicate ceramic (ZLS), which combines the positive properties of zirconia and glassceramics. Due to the 10% proportion of finely dispersed zircon oxide, following crystallisation a very homogeneous structure is created in this glass-ceramic with an average particle size of approx. 0.5 μm that not only has outstanding mechanical properties but also exceptional optical properties.
