STEP 14: Light cure the flowable composite and reinforcement material with a hand-held curing light. Be careful to keep the flowable composite off the retentive wing areas of the eFiber. Again, I recommend that two people complete this step: one holds the eFiber in position with an instrument while the other holds the curing light. Otherwise, the eFiber might move during curing.
STEP 5: Using the putty matrix to position the tooth back on the cast, draw or mark the position of the retentive groove to be cut on the lingual of the tooth. Keep in mind you want the retention wings to be out of occlusion, so you may want to cut the retentive groove as a semi-circle or arc to assist in positioning the retention wings in the cingulum area.
STEP 17: The bondable, non-invasive esthetic temporary is ready to be sent to the dentist. I recommend cutting back the putty matrix so the dentist can use it as a bonding index to hold the restoration in place during bonding. Include the bonding instructions for the dentist.
STEP 1: Mount casts on a simple articulator using the bite registration if supplied. When you’re preparing the restoration prior to tooth extraction, remove it from the cast as you do for an immediate denture and keep in mind the pontic design.
STEP 4: Use a little utility wax to hold the tooth on the cast in the desired position and make a labial putty matrix, which holds the tooth in position during fabrication and may also be used later by the dentist as a bonding matrix (see Step 17). Place eFiber within the normal contours of the denture tooth by cutting a retentive groove in the lingual of the tooth.
STEP 15: I like to add tooth-colored acrylic to fill in the pontic area. If necessary, you can add a flange on the labial with tissue-shaded acrylic. Don’t forget to place a separator on the model and eFiber adhesive on the tooth before adding the acrylic.
STEP 16: Complete any final adjustment to the lingual surfaces of the eFiber and composite using silicone polishers. I use a small polishing wheel made of chamois sandwiched between goat hair brushes along with some eFiber polish to achieve a beautiful luster.
