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.

General Handling and Storage 

❘❙❚ Store FibreKor material at or below 2°– 8°C. 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)

1. Using diestone material, pour the impression and prepare the model/die in the usual manner. Prepare this model so it is removable from 

the articulator. This will allow the model to fit into the Sculpture ® Curing Light. 

2. Optional Step – Re-pour impression using diestone material without pins for a "solid model technique." 

3. Inspect die and blockout any undercut. Note: All die blockout should be accomplished with high temperature inlay-wax, polymer 

blockout material or gypsum material prior to sealing the die. 

4. Mark and define the margins of the abutment dies with a permanent marking pencil. (Fig 1) 

5. Protect and seal the margins by applying a thin coat of Zip Sep * Sealer (Fig 2). Apply a second coat within 15 seconds. Allow to dry 

for 2 minutes. 

6. Paint a thin coat of Sculpture Plus Die Spacer all over the die, including margins (Fig 3). Allow to dry for 5 minutes. For a more 

passive fit, a second or third coat should be applied. Keep any additional coats 1mm away from the margin. Sculpture Plus Die Spacer 

also acts as a separator. 

7. Use Zip Sep* Sealer to seal contact areas, opposing models and saddle areas (Fig 4). Note: Use Zip Sep* Sealer and Zip Sep* 

Universal Separator when adding to short, incomplete margins on the die.

The indexing technique allows the build-up of the base of the bridge framework within an impression or "matrix" rather than free hand 

on a model. This technique substitutes for only a portion of the standard framework build-up as it includes only the span of the box 

preparations and the pontic form. The framework still requires finishing with standard technique that includes, at minimum, an application 

of FibreKor material over the occlusal surface of the abutment preparations. This technique may not be suitable for all FibreKor 

framework build-ups. 


2. Build a wax up of the bridge framework on the model, including only the span of the box preps and the pontic form (Fig 1). 

Ensure that the pontic wax up allows for a minimum of 1-2mm of Sculpture Plus composite overlay to full contour. 

3. Prepare Correct Plus ® impression material (Item Code Q34H). 

a. Dispense equal amounts of catalyst and base. (Fig 2) 

b. Mix or knead material until a uniform color is reached. (Fig 3) 

4. Create a matrix for the framework by placing the wax framework into the impression material gingival side first. (Fig 4) Allow to set 

for approximately 5 minutes. 

5. Remove the wax up from the matrix to expose the framework shape. (Fig 5) 

6. Apply FibreFlo resin to the surface impression in the matrix. (Fig 6)
