The 3M ESPE RelyX U200 Self-Adhesive Resin Cement is a high-performance dental cement designed for easy and reliable permanent cementation of various restorations, offering excellent bond strength on different substrates like ceramics, composites, and metals. Its unique dual-cure formulation not only ensures a secure bond but also minimizes post-operative sensitivities and handles moisture exceptionally well, contributing to its lasting stability and robust mechanical properties. Featuring the innovative Clicker? delivery system, the cement provides effortless mixing and application. This system allows for flexible dosing and simultaneous application of both base and catalyst pastes, reducing material wastage and enhancing efficiency. The cement's chemistry builds upon a proven foundation, utilizing a phosphoric acid methacrylate adhesion monomer and specialized fillers that enable strong adhesion and offer a distinct neutralization behavior. The cement's mechanical prowess is impressive, boasting high flexural and compressive strength, as well as a notable modulus of elasticity and surface hardness. Notably, its color stability and resistance to discoloration contribute to the restoration's overall esthetic appeal. In comparison to traditional multi-step resin cements, the self-adhesive mechanism of RelyX U200 streamlines the bonding process, offering both simplicity and outstanding performance. RelyX?
