Since the release of Admira Fusion in January 2016, nano-ORMOCER technology and the Admira Fusion family of products have changed clinicians' expectations in regards to initial shrinkage, shrinkage stress, esthetics, and biocompatibility.

In the modern world of cosmetic and restorative dentistry, the all-ceramic crown restoration is considered the pinnacle of quality as an indirect restoration for strength, esthetics, and longevity. A year ago, Voco took an evolutionary step forward in direct restorative dental materials with the introduction of Admira Fusion, the world’s first all-ceramic-based universal direct restorative material. After nearly two decades of research and development, Voco created the first ever nano-ORMOCERthrough the fusion of Voco’s nano-hybrid and ORMOCER (organically modified ceramic) technologies.

Nano-hybrid technology was first introduced to the dental industry in 2003 when Voco launched Grandio, the world’s first nano-hybrid composite. ORMOCER technology, developed by the German-based Fraunhofer Institute for Silicate Research ISC, has been embraced and implemented by other industries with success. Its widened use is due to its beneficial optical properties, scratch resistance, anti-static qualities, and anti-microbial behaviors. These benefits have created higher levels of quality for industries using medical technologies, electronics, optics, sensors, and surface refinements. Voco brought these two successful technologies together as a nano-ORMOCER in Admira Fusion to create new levels of quality within the dental industry.
As a nano-ORMOCER, Admira Fusion’s chemical base is formed by silicon oxide, making up both the glass fillers as well as the ceramic resin matrix. The compound is a first of its kind, and the unique “pure silicate technology” offers advantages, including up to 50% less polymerization shrinkage (1.25% by volume) than today’s conventional composites, as well as up to 50% lower shrinkage stress. Further physical properties include extremely high color stability, elevated esthetics in translucency and opacity that allow it to adapt and blend well to surrounding tooth structure, and high surface hardness and edge strength.
The ORMOCER used in the manufacturing of Admira Fusion makes it highly biocompatible, as it contains none of today’s classic monomers (BisGMA [BPA], TEGDMA, UDMA, etc). The light-curing, radiopaque Admira Fusion has an 84 % (by weight) inorganic filler content, giving it excellent wear resistance. When combined with Admira Fusion’s particularly high color stability, it allows for universal use, meeting the highest demands in both the anterior and posterior regions. The homogeneous material offers non-sticky handling and is compatible with all conventional bonding materials.
Further value is realized with Voco’s ISO-pak packaging of Admira Fusion capsules, which offers air-tight individually sealed foils to maximize infection and humidity control. It is available in 18 VITA shades in unit-dose capsules and syringes.
As the manufacturer notes, "Admira Fusion’s nano-ORMOCER technology represents the next generation in the world of universal direct restorative materials."
