9. Place the assembled strip across the length of the preparation and lingual to the established bar as shown. (Fig 7)
10. Apply additional strips of FibreKor material as space allows. Note: A larger FibreKor framework will provide stronger support.
Maximize the size of the FibreKor framework without compromising the esthetics of the final restoration. The amount and size of
FibreKor material used for Maryland bridges may vary greatly depending on the constraints of the individual case.
11. Carefully spread the FibreKor fibers. Work to adapt and distribute fibers evenly across the lingual surface of the abutment wings. (Fig 8)
12. Gently press and form the FibreKor strips across the inter-proximal span to ensure contact between all layers of FibreKor
material.
13. Use the opposing cast to shape proper curvature of the inter-proximal bar and ensure proper contour of the pontic.
14. Apply a strip of 16K FibreKor material to the gingival surface of the bar to create the pontic form (Fig 9). A FibreKor strip may be placed
on the incisal surface of the bar if space permits. Be sure to leave room to cover the framework with 1-2mm of Sculpture
Plus Composite.
15. Apply a thin layer of FibreFlo resin to the lingual surface of the pontic area. (Fig10)
16. Apply strips of the selected shade of FibreKor 2K or 4K material across the lingual and/or labial surfaces in the incisal/gingival
direction as space permits (Fig 11). Adapt the strip to the incisal surface to reinforce the pontic framework.
17. Cure in the Sculpture Curing Light using the Build-up cycle. (Fig 12). Do not cure FibreKor frameworks in the Sculpture Curing Light
Final cycle.
