Zirconomer Improved defines a new class of restorative that promises the strength and durability of amalgam with the protective benefits of glass ionomer while completely eliminating the hazard of mercury. This high strength restorative has been specially reinforced with nano-zirconia fillers that not only impart remarkable mechanical properties to the restoration for posterior load bearing areas but also provides enough translucency to match natural tooth. Combination of outstanding strength, durability and sustained fluoride protection deems it ideal for permanent posterior restoration in patients with high caries incidence as well as cases where strong structural cores and bases are essential.
