Please provide the FibreKor Preparation Guide to your dentist and review prior to operative procedures.
Ensure that a posterior proximal box or anterior step is provided on all abutment preparations.
Avoid fiber exposure in the oral environment. FibreKor frameworks should be completely covered in Sculpture Plus composite.
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.
1. Prepare die/model as described on Page 4. Ensure that the model is removable from the articulator.
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)
