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.
1. Prepare die/model as described on Page 4. Ensure that the model is removable from the articulator.
2. Apply a thin layer of Sculpture Plus Body material to the lingual wings of the prepared abutment dies (Fig 1). Do not cure.
Note: For additional details on Sculpture Plus composite build-up technique refer to the Sculpture Plus Instruction Manual.
3. Measure the longest distance of the inter-proximal span including the mesial and distal box preps. (Fig 2)

material as space permits. FibreKor strips should fill the box preparation area completely. Do not cure.
