3M RelyX Unicem 2 – Self-Adhesive Dual-Cure Resin Cement (Automix / Clicker)

3M RelyX Unicem 2 is a market-leading self-adhesive resin cement that streamlines the cementation of indirect restorations into a single, reliable step. Its self-adhesive chemistry removes the need for separate etching, priming, or bonding — saving valuable chair time while delivering the strong, durable bond you expect from a premium resin cement.

Featuring dual-cure technology, RelyX Unicem 2 combines chemical and light activation so it sets predictably even in areas the curing light cannot fully reach — ideal for deep restorations, posts, and full-coverage crowns. Its excellent moisture tolerance means it performs reliably in the real conditions of the oral environment, and its formulation is designed for virtually no post-operative sensitivity, keeping patients comfortable.

Beyond strength, RelyX Unicem 2 offers outstanding esthetic stability, resisting discoloration over time for natural-looking, long-lasting results. Flexible dosing and easy cleanup make handling straightforward for every case.
