I have been using RelyX Unicem [3M ESPE] for about 2 years with great success. I have absolutely no complaints. Easy to use and works great. But I have heard that resin modified glass ionomer cements have fluoride release that prevents caries. There is also RelyX Luting Plus which is sort of the resin modified glass ionomer version of RelyX Unicem. Also this kind of fluoride recharges over time so that the fluoride release continues. My concern is that I want a cement that I can use for both PFMs and ceramic restorations. Can I use a resin modified glass ionomer to cement ceramic restorations? If so, what are your thoughts on RelyX? Is this the best one on the market or are there better alternatives?
According to 3M: “RelyX Luting Plus is an advanced paste-paste, resin-modified glass ionomer formula in the convenient Clicker™ Dispenser. Strong mechanical properties and easy handling make it the perfect choice for cementing routine restorations.
Easy to mix, load and seat Consistent mix ratios Enhanced marginal integrity with low solubility High fracture toughness Sustained fluoride release Virtually no post operative sensitivity
