e.max Cement or Bond?

Anterior Veneers:

  • Restorations must be bonded because the preparation lacks inherent retention and resistance form.
  • Bonding means following a protocol of creating a hybrid zone by etching, priming and applying a resin.
  • Utilize materials that are light cure only, dual cure materials carry a risk of color shift over time.

Posterior Partial Coverage ( Inlays & Onlays):

  • Restorations must be bonded because the preparations lack inherent retention and resistance form.
  • Bonding means following a protocol of creating a hybrid zone by etching, priming and applying a resin.
  • dual cure materials have the advantage of creating a gel phase for cleaning, but the insurance of dual cure at depth where light may not penetrate effectively.

Anterior & Posterior Full Coverage:

  • Restorations with retention form and resistance form can be either bonded or cemented.
  • Choosing between bonding and cementation is based on personal preference, obtaining isolation and concern over replacing the restorations in the future.
  • Resin cements utilize a chemical catalyst and could be at risk for color change over time, balance this against your confidence in light penetration using light cure only products.
  • depending on the e.max material used it may be translucent and using a white or opaque cement may alter your esthetics.
