RESTORATIVE DENTIST - 1st Visit 1. See the BIOMET 3i Restorative Manual or consult the specific implant system manual for abutment placement and abutment level or implant level impressioning instructions.
LABORATORY 2. Fabricate a soft tissue master cast as illustrated using new or undamaged analogs. Cases received with either damaged or insufficiently anchored analogs will be returned to the laboratory. NOTE: The soft tissue material on the master cast must be applied approximately 2mm down from the analog interfaces. It must also be easily removable.
3. Place non-hexed titanium implant or abutment temporary cylinders onto the analogs and screw into place with waxing or try-in screws. Fabricate a rigid verification index by luting the cylinders together using a light cure composite resin or autopolymerizing acrylic resin. Also, fabricate a baseplate and wax the occlusal rim. Return the verification index for intraoral fit verification and wax occlusal rim for interocclusal records.
RESTORATIVE DENTIST - 2nd Visit 4. Remove the healing abutments or caps using the proper driver. Place the wax occlusal rim into the mouth and make the interocclusal records. Place the verification index onto the implants or abutments. Place a try-in screw into one posterior most cylinder of the verification index and finger tighten. Visually verify a passive fit on all interfaces. If the interfaces are subgingival, take a radiograph to verify a passive fit. Remove the screw and place into the opposite posterior most cylinder of the verification index and repeat. If a fit discrepancy is found, section the index and reassemble it intraorally by luting with a resin material. Remove the index. Immediately replace the healing abutments or caps.
LABORATORY 5. Verify that the analog positions on the cast are accurate using the verification index. If a fit discrepancy is found, remove the analog(s) and replace these in the cast using the corrected verification index. Articulate the casts using the interocclusal record. Set the denture teeth on the baseplate and return the wax try-in for verification.
RESTORATIVE DENTIST - 3rd Visit 6. Remove the healing abutments or caps and place the wax try-in into the mouth. Verify occlusion, aesthetics and phonetics. Make any necessary adjustments. If major adjustments are necessary, make a new interocclusal record and return to the laboratory for a new set-up and wax try-in.
