Hi,
Knowing that zirconia isn't often used on veneers due to low/no mechanical retention, some doctors still request it from time to time. A doctor asked us for the best cement for zirconia veneers, but zirconia manufacturers aren't willing to "recommend" any cement due to the aforementioned reason.
I did some quick researching and put together this recommended procedure based off of a research paper, and some material IFUs. It seems excessive, but may give the veneer the best chance of retaining adhesion/bond.
Would you, please, review the procedure and offer your constructive criticism?

- Thoroughly rinse and dry the intaglio surface of the veneer.
- Apply Ivoclean (Ivoclar Vivadent) to intaglio surface of veneer with brush. Let react for 20 seconds. Then thoroughly rinse and dry.
- Abrade intaglio surface of veneer with silica coated aluminum oxide (Rocatec, 3M ESPE) for 20 seconds. Then dry.
- Apply silane (Monobond Plus, Ivoclar Vivadent),let react for 60 seconds, then disperse excess with strong stream of air. Let dry.
- Perform prophylaxis of the tooth surface with pumice and water. Then thoroughly wash and dry.
- Etch with 35% Phosphoric Acid for 20 seconds. Then thoroughly wash and dry.
- Treat with application of adhesive system (Excite F, Ivoclar Vivadent).
- Apply resin cement (Variolink Esthetic DC, Ivoclar Vivadent) to veneer. Place veneer on abutment. Remove excess cement with brush and floss.
- Light cure (≥ 1,000 mW/cm²) for 40 seconds on veneer surface.
- Apply glycerin gel/air block (Liquid Strip, Ivoclar Vivadent) to cervical and incisal regions of veneer.
- Light cure (≥ 1,000 mW/cm²) for another 40 seconds.
- Rinse off glycerin gel/air block. Remove excess cured cement with scalpel blade.
