3M ESPE RelyX U200 Self-Adhesive Resin Cement

Cementing an indirect restoration usually means a few separate steps — etch, prime, bond, then finally cement. 3M ESPE RelyX U200 cuts that down. It's a self-adhesive, dual-cure resin cement designed to handle most cases without separate etching, priming, or bonding, which means less time per seat and fewer steps where something can go slightly wrong. You can pick between the Clicker™ dispenser or the Automix syringe, depending on how your practice prefers to work. Both give you consistent, accurate dispensing with minimal waste — the Clicker™ doses out equal amounts of base and catalyst for hand-mixing, while the Automix syringe mixes automatically through the tip as you dispense. One detail worth knowing: RelyX U200 behaves differently depending on the stage of cementation. While you're placing the restoration, it stays hydrophilic, so it tolerates a bit of moisture in the field without compromising adaptation. Once it's cured, it shifts to hydrophobic, which helps resist water uptake, staining, and breakdown over time. That's a meaningful part of why it holds up well clinically. Because it's dual-cure, you're not relying on light penetration alone. It self-cures fully even in areas your curing light can't reach — deep margins, posts, anywhere light access is limited — with the option to light-cure exposed surfaces for a faster set. Add in solid compressive and flexural strength, good color stability, and comparatively low postoperative sensitivity, and it's a dependable everyday cement for routine indirect work. RelyX U200 is suitable for crowns, bridges, inlays, onlays, posts, Maryland bridges, and implant-supported restorations — covering most of what you'd reach for a permanent resin cement to do.
