CHICAGO - 3M ESPE introduced an adhesive resin cement at the Chicago Dental Society Midwinter Meeting this week that the company says delivers significantly higher bond strength, initially and over time, when combined with Scotchbond Universal adhesive.

Approved for a wide range of indications, RelyX Ultimate adhesive resin cement is approved for all indications, including veneers, inlays, onlays, crowns, and bridges, and is ideally suited for CAD/CAM and glass ceramic restorations, the company noted.

RelyX Ultimate's unique formulation includes an integrated component that activates the dark cure function of the adhesive and eliminates the need for an additional activator, according to 3M ESPE. Scotchbond Universal adhesive functions as a silane agent for glass ceramics, as well as a zirconia and metal primer.

"With the new materials such as zirconia and glass ceramics, there is simply a need for greater bond strength," a company representative told

In a study presented at the 2011 International Association for Dental Research Continental European Division meeting comparing RelyX Ultimate plus Scothbond Universal with several competing products, researchers found that RelyX Ultimate delivered stronger or comparable bond strength to enamel at 24 hours and long term.

RelyX Ultimate cement comes in total-, selective-, or self-etch and is available in four fluorescent shades that provide life-like fluorescence and color stability, according to 3M ESPE.

RelyX Ultimate cement trial kits (available in A1 and translucent shades) include a variety of mixing tips: regular, wide, and intraoral. The dual-barrel syringe contains 8.5 grams of cement paste, which is enough material for approximately 16 applications.

The product will launch in March.
