  4. Cementation • Adhesion • “total-etch”, resin cement • Semi-adhesion • Self-etching resin cement • Non-adhesion • Glass Ionomer, resinionomer, zinc phosphate, polycarboxylate

  5. Cement Requirements • Lack of post-operative sensitivity • Strong bond and good seal -to the tooth and to the restorative material • Easy placement and clean-up • Esthetics compatible with the restorative material • Minimal film thickness • Radiopaque (posterior)

  6. “Total-etch”with Resin Cement Powder liquid ceramic or Pressed ceramic restorations

  7. “Tack & Wave” Cementation Veneers and anterior crowns

  8. Emprethin evaluation

  9. Be Careful!!! 0.2 mm glass is fragile!

  10. OptraGate (Ivoclar)

  11. Hydrogen Peroxide in Ultradent Syringe

  12. Metal strip removes any interproximal Luxatemp and freshens the enamel

  13. Try in independently DRY

  14. Occlude Spray Powder (Pascal)

  15. Try-in collectively DRY! • Check complete seating • Proximal contacts

  16. Mesial Surface Dry Erase Marker

  17. Distal Surface

  18. Variolink Veneer(Ivoclar/Vivadent) • Value based • 0 • +1, +2, +3 • -1, -2, -3 • Microfill

  19. +2 0

  20. Clean and acidify with 35% Phosphoric acid

  21. Silane Coupling Agent (Relyx Ceramic primer) placed for 1 minute

  22. Place bonding agent (All Bond 3) inside dry restoration

  23. Load restoration with resin cement

  24. Vivapad (Ivoclar)

  25. Etch with 35% phosphoric acid for 15 seconds per tooth

  26. Apply Systemp desensitizer for 15 seconds

  27. Effect of Remoistening Water vs. Desensitizer/Rewetting Agent Water-blotted dry 22.8 Water- wet 19.2 Gluma Desensitizer 22.3 HurriSeal 20.1 Vivadent Desensitizer 25.8 MicroPrime 20.1 Aqua-Prep 18.1 Dentinal Bond Product

  28. “suction” away excess; do not desiccate

  29. Apply 2 coats of All Bond 3 A & B Primer mix

  30. Adec Warm Air Tooth Dryer

  31. Seat all restorations at one time; do not remove excess resin cement

  32. Polymerize “dead center” each restoration for 1 second using a 2.0 mm light guide (Ivoclar)

  33. Hold light guide 1 inch from restorations and light cure 3-5 seconds on facial and lingual

  34. General Guidelines • +2: 5 seconds • 0: 3 seconds • -3: 5 seconds +

  35. “Pick" away excess using Bard Parker or scaler

  36. Floss through contacts using a Brasseler Serrated Saw

  37. Floss through contacts using waxed dental floss

  38. Place DeOx (Ultradent) on all margins

  39. Light polymerize for at least 60 seconds per tooth from both buccal and lingual

  40. Curing Lights • Photoinitiators • Camphoroquinone- 470-490 nm • PhenylDipropandione- 430 nm
