BONDING INSTRUCTIONS
Crowns, Inlays, Onlays & Veneers
Note: Proper internal surface preparation of the restoration is required prior to these clinical procedures. (e.g. hydrofluoric acid etch IPS Empress restoration with IPS Ceramic Etch, see laboratory or manufacturer's instructions)

1. Remove temporary, clean and dry preparation.	2. Try in the final restoration with Variolink Try-In paste, or with glycerine gel. (Liquid Strip)	3. Isolate operating field with appropriate devices.
4.Treat isolated preparation with preferred new generation enamel/dentin bonding system per manufacturer?s instructions. SYNTAC - Etch enamel, rinse and dry. - Apply Syntac Primers, 15 seconds. Dry. - Apply Syntac Adhesive. Dry. - Apply Heliobond thin with air.	5. Clean internal aspects of phosphoric acid for 15 seconds.	6. Apply silane coupler (Monobond-S) to internal surfaces, let dry 60 seconds. Apply unfilled resin (Heliobond) to internal surfaces, thin with air and protect restoration from light.
7. Select appropriate shade and viscosity of Variolink. Dispense and mix base and catalyst in a 1:1 ratio.	8. Place mixed cement into restoration and onto preparation if possible. Seat restoration with slow, even pressure.	9. Maintain seating pressure and remove excess cement with a dry brush, or  a brush dipped in unfilled resin (Heliobond).
10. Optional: Apply Liquid Strip to margins (see Advanced Techniques, Method 2).	11. Light cure the final restoration from all aspects for a minimum of 40 seconds each	12. Adjust and finish with fine diamonds. Complete final polishing with Politip Finishers/Polishers and Diamond Polishing Paste.
