9. Place the assembled strip across the length of the preparation and on top of the 16K bundle. (Fig 7)
10. Gently press and form the FibreKor strips across the bar that has been formed to ensure contact between all layers of FibreKor and
Sculpture Plus material.
11. Carefully shape and adapt the FibreKor material across the pontic span using tweezers as shown (Fig 8). Work the material as
needed to remove any voids between layers. Do not cure.
12. Ensure that the height of the bar in the proximal span is not higher than the occlusal table of either abutment.
13. Bend the formed bar across the pontic span to attain the proper occlusal plane (Fig 9). Ensure that the framework is not touching
any area of soft tissue. Do not cure.
14. Create the pontic form by placing a short strip of FibreKor 16K on the lingual and on the buccal of the formed bar as shown
(Fig 10). Adapt to the formed bar. Note: FibreKor material forms only the framework for the restoration. Be sure to leave room to
cover the framework with 1–2mm of Sculpture Plus Composite.
15. Apply a small amount of FibreFlo resin to the occlusal area of the pontic. (Fig 11)
16. Position and apply short strips of FibreKor 2K or 4K material perpendicular to the buccal and lingual strips of the pontic to form
the pontic occlusal table (Fig 12). Note: The formation of the pontic occlusal table is essential to support the build-up of the
pontic with Sculpture Plus composite. If the pontic will be subject to high stress, consider using the alternate wrap technique
described on Page 19 to create the occlusal table.
