Users of dental zirconia are really spoilt for choice these days. Countless manufacturers offer zirconia materials that differ in their mechanical and optical properties and indication range. What is not apparent at first sight is that the available products also differ with respect to the quality of the CAD/CAM blanks offered. Blank quality is highly dependent on the quality of the raw materials and is affected by different aspects during raw material processing, pressing and pre-sintering. This has a huge impact on the surface quality, edge stability, fit and processing requirements of milled restorations.
HATTERSHEIM AM MAIN, Germany: During these strange and difficult times caused by the COVID-19 pandemic, the top priority for dentists across the world has been to keep themselves and their patients safe. To do so, not only have many dental practices been shut down, but also in-person dental congresses, symposia and other events have been postponed indefinitely.
The use of pre-shaded zirconia with a highly translucent gradient brings more efficiency into the dental laboratory. Owing to the advanced properties of materials like KATANA Zirconia multilayered discs, true-to-life restorations can be created without any, or with only a thin vestibular layer of, veneering porcelain. This saves considerable time in the laboratory.
