Evaluators’ Comments

  • “Does not affect the shade of translucent crowns.”
  • “This company has developed some very specific products that are perfect for their individual uses.”
  • “The gel state clean-up prior to light curing was easier than a total self-cure, but the overall time spent due to the extra light-cure step was longer.”
  • “A quicker setting/self-curing time would be helpful, and an initiator so that light-curing is not needed.”
  • “I prefer letting it set undisturbed for 1.5 minutes rather a quick cure prior to excess removal.”

Indication

  • Adhesion of zirconia restorations

Clinical Tips

  • Clean-up is much easier if you don’t let it get too hard.
  • Floss through contact points before the gel phase.
  • Floss interproximally and leave the floss in place until the cement is fully cured.
  • Use the intraoral tip for accurate placement of the material into the intaglio of the crowns.
  • If you are using it for the first time, check the setting every 15 seconds as the material becomes very hard if left beyond the
    ideal time for clean-up.
  • The mixing tip is small. We extruded the product onto a mixing pad and then mixed, reducing the amount of wasted product.
