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. * Zip Sep is a trademark of Dental Ventures of America, Inc.

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. 1. Prepare die/model as described on Page 4. Ensure that the model can be removed from the articulator. 2. Apply a thin layer of Sculpture Plus Body material to the floor and margins of the inter-proximal area. (Fig 1) Note: For additional details on preparing and using Sculpture Plus Composites refer to the Sculpture Plus <strong>Instruction</strong> Manual. 3. Measure the distance of the inter-proximal span including the mesial and distal box preps. (Fig 2) 4. Measure and cut the FibreKor 16K material to the same length. (Fig 3) 5. Position this strip of FibreKor 16K material in the inter-proximal boxes as shown and press gently into place. Do not cure. (Fig 4) 6. Measure the distance between abutments including the mesio-distal width of the occlusal tables. (Fig 5) 7. Measure, mark and cut 2 strips of the desired shade of FibreKor 4K material to the same length. A single strip of 16K material may be used here in place of the two 4K strips if space permits. 8. Neatly stack the two strips of 4K material and flatten together into a single bar. (Fig 6) Fig. 1 Fig. 2 Fig. 3 Fig. 4 Fig. 5 Fig. 6 5
