Maxcem Elite Advancements

The Redox Advantage:
The Powerful Chemistry Behind Maxcem Elite and NX3

Maxcem Elite and NX3 are top in their categories due to Kerr's unique proprietary redox initiator system. This breakthrough technology, present in both cements, is the reason behind their outstanding success. Most self-cure or dual-cure resin cements on the market today use a benzoyl peroxide (BPO) and tertiary amine pair as their redox initiator system to initiate polymerization and curing a system inherent with problems. The unique redox initiator system present in Maxcem Elite and NX3 eliminates these problems.

Initiator systems using BPO/amine have two significant color stability flaws. First, the catalyst paste on its own will progressively discolor (yellowish tint) upon storage on the shelf. Second, the self-cured or dual-cured cement will progressively discolor over time, compromising long-term esthetics. Kerr's proprietary redox initiator system offers significant advantages over BPO/amine initiator systems, eliminating the undesirable discoloration and resulting in a more esthetic restoration.

Both cements are noted for superior performance in self-cure situations where there is limited light accessibility due to the proprietary redox initiator system. NX3, compatible with total-etch and self-etch adhesives, does not require a dual-cure activator. Maxcem Elite, a self-etch self-adhering resin cement, has a very efficient self-cure mechanism that allows it to set up quickly in the absence of light curing. Doctors can confidently use Maxcem Elite when cementing non-translucent (metal-based) restorations.

Color Stability

Kerr's patented redox initiator system delivers superb color stability before, during and after curing. (Clear shades tested.)

Bond Strength

NX3 is indicated for veneers, inlays, onlays, crowns, bridges and posts, as well as for adhesive bonding of amalgam restorations and as a core-buildup material.

NX3 has excellent compatibility with acidic adhesives. This eliminates the need for a dual-cure activator for the adhesive, simplifying the cementation procedure.

Maxcem Elite achieves greater bond strengths using a combination of adhesive monomers, including GPDM (glyceroldimethacrylate dihydrogen phosphate) and the patented Redox Initiator System that provides an efficient curing mechanism. Maxcem Elite is indicated for inlays, onlays crowns, bridges and posts.
