Intaglio of Crowns

Intaglio of Crowns
For Bonding

e. Max intaglio:

  • Ivoclar recommends NOT to air abrade intaglio (can start propagation of micro cracks)Intaglio of Crowns
  • YES hydrofluoric acid
  • YES phosphoric acid
  • YES Ivoclean
  • YES silane (for stronger chemical bond)
  • YES heating silane layer (with eg ADEC warm air tooth dryer can enhance bond strength)

Zirconia intaglio:

Intaglio of Crowns

  • YES air abrade intaglioIntaglio of Crowns
  • NO HF acid
  • NO phosphoric acid
  • YES Ivoclean
  • YES silane (MDP base)

If LAB fabricated, check if the lab have etched the restoration and applied silane. If the restoration has
not been etched or silanted, RE-ETCHING at chairside will result in overetching which compromises the
bond strength of the resin to the ceramic and results in a decrease in mechanical properties

Wear gloves and eye protection when using this highly corrosive gel

Two types of Hydrofluoric Acid:

  • Ivoclar: 5% IPS Ceramic Etching Gel and Neutralising Powder
  • Henry Schein: Ultradent 9% buffered HF acid -ULT-0405
