Apply a small amount of FibreFlo resin onto the axial walls and in the lingual and buccal corners of the abutment as shown. (Fig 19) 29. Using tweezers, gently form the remaining length of FibreKor 4K material around the axial walls of the abutment. (Fig 20) 30. Carefully adapt the material to the corner of the abutment and to the lingual surface of the bar. (Fig 21) 31. Ensure that the loop of 4K material is thoroughly adapted to the framework with no voids between layers. 32. Light cure with the Spectra-Lite ® cure light, or equivalent, for 30 seconds. (Fig 22) 33. Repeat steps 19 to 32 for the remaining abutment. 34. Create the pontic form by placing a short strip of FibreKor 16K material on the lingual and on the buccal of the formed bar as shown (Fig 23). 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 1-2 mm of Sculpture Plus Composite. 35. Apply a small amount of FibreFlo resin to the occlusal area of the pontic. (Fig 24) Fig. 19 Fig. 20 Fig. 21 Fig. 22 Fig. 23 Fig. 24 12

Position and apply short strips of FibreKor 2K or 4K material perpendicular to the buccal and lingual strips of the pontic form to form the pontic occlusal table (Fig 25). 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. 37. Fill in any voids between FibreKor layers with FibreFlo resin. 38. Cure in the Sculpture Curing Light using the Build-Up cycle. (Fig 26). Do not cure FibreKor frameworks in the Sculpture Curing Light Final cycle. 39. Remove the dies from the model and place a small ball of the selected shade of Sculpture Plus Body on the saddle area. Note: If the pontic requires a thick composite overlay, consider layering a lighter body shade to achieve the desired shade result. Use opaceous material as needed to enhance or modify final shading. 40. Fully seat the dies back onto the model and ensure that the framework is stable. (Fig 27) 41. Adapt the Sculpture Plus Body material to the buccal and lingual surfaces of the FibreKor framework to form the pontic. Leave embrasures open. 42. Cure in the Sculpture Curing Light using the Build-Up cycle. 43. Build-up the bodies of the abutment crowns and the pontic with the selected shade(s) of Sculpture Plus Body using the technique described in the Sculpture Plus <strong>Instruction</strong> Manual. (Fig 28) Note: For maximum polymerization of Sculpture Plus Composites, curing is recommended after each 1mm addition of material. 44. Cure in the Sculpture Curing Light using the Build-Up cycle. 45. Apply the appropriate shade(s) of Sculpture Plus Incisal to the abutment crowns and pontic (Fig 29). Build to full contour. If desired, use Sculpture Plus Transparent Incisal sparingly to reduce opacity. Fig. 25 Fig. 26 Fig. 27 Fig. 28 Fig. 29 13
