F I B E R R E I N F O R C E D C O M P O S I T E S ( F R C ) FIBREKOR ® FRC IS A UNIQUE COMPOSITION of fine, unidirectional glass fibers combined with resin for the fabrication of fiber-reinforced, metal-free bridges. Each FibreKor bundle contains thousands of fibers with an average diameter of 8µ to produce a bridge substructure that is strong, translucent and bonds seamlessly with the composite build-up. Metal-free bridge substructures offer a lightweight and esthetic alternative to metal bridge frameworks without the hyper-sensitivity issues that accompany metal alloys. THE RESIN FORMULATION FOR FIBREKOR ® FRC is similar to the resin formulation for Sculpture Plus Composites, the overlay material indicated for FibreKor frameworks. As Sculpture Plus composite is added to the FibreKor framework and cured, the resins in both products cure together. The end result is a finished bridge that fully integrates the fiber framework with the composite build up, virtually eliminating the possibility of the build up de-bonding from the framework. FIBREKOR ® FRC IS AVAILABLE IN 2K, 4K AND 16K BUNDLE SIZES to provide versatility, ease of handling and maximum strength for metal-free bridge restorations. The 2K bundle contains 2,000 individual glass fibers and the 4K bundle contains 4,000 glass fibers; both bundle sizes are available in A, B, C, D and Clear shades. The 16K bundle contains 16,000 individual glass fibers with a filled resin for increased strength and overall quality. The 16K bundle is used to form a strong initial base for the bridge framework and is available in a single universal shade. 2

Refrigeration is required. ❘❙❚ For best handling, bring material to room temperature. Remove from refrigerator 15–20 minutes prior to use. ❘❙❚ Cover FibreKor material with the light blocking cover when not in use to prevent premature polymerization from ambient light. Basic Handling Technique ❘❙❚ FibreKor 2K and 4K bundles are tightly packaged between two polyester strips to protect the material. Remove the clear strip from the top of the material. Using tweezers or another sharp instrument, peel up one end of the FibreKor material from the polyester backing ensuring that all fibers are lifted up from the backing and remain intact. Secure the end of the bundle with tweezers, lift the bundle from the backing and place on a glass slab. (Fig 1) FibreKor 16K bundles are loosely packaged between two polyester strips to protect their shape. Carefully remove 16K bundles from the packaging and transfer to a glass slab. Avoid over-handling or flattening the material unintentionally. ❘❙❚ FibreKor materials are measured and cut to size for application to models. Determine proper length, then measure (Fig 2) and mark the FibreKor strip using the FibreKor ruler. (Fig 3) ❘❙❚ Cut FibreKor bundles to length using FibreKor ceramic scissors (Fig 4). Use extra care when cutting the FibreKor 16K bundle to avoid crushing or flattening the bundle. Replace ceramic scissors as necessary. ❘❙❚ 2K and 4K FibreKor bundles are often stacked together for application to a model. Neatly stack two strips of equal length together (Fig 5). Gently flatten the two strips together to form a single bar. (Fig 6) Fig. 1 Fig. 2 Fig. 3 Fig. 4 Fig. 5 Fig. 6 3
