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.
