It is also indicated for the cementation of PFM, metal, all-alumina and all-zirconia restorations on implant abutments. 3M ESPE RelyX Luting Plus Automix has a working time of 1.5 minutes from start of mixing. It should be tack light cured for five seconds per surface. It self-cures to a gel-phase in two minutes with a full setting time of five minutes after placement in the mouth.

3M ESPE RelyX Luting Plus Automix is an excellent cement for use with metal-, alumina- or zirconia-based restorations. The automix delivery is convenient and easy to use, providing a homogeneous mix every time. The consistency is creamy with a low viscosity that allows complete seating of the restoration with little pressure. The ability to tack cure the cement for quick clean-up of excess cement was a favorite feature of consultants. One color, white, is available. Some consultants expressed a desire for a more neutral shade for use under translucent all-zirconia crowns. Fifty-three percent of consultants reported that 3M ESPE RelyX Luting Plus Automix was better than their current resin-modified glass ionomer luting cement and 44% reported it was equivalent. Eighty-eight percent of consultants would switch to 3M ESPE RelyX Luting Plus Automix and 97% would recommend it.
- Ensure the tooth is not desiccated before cementation to minimize sensitivity.
- Tack curing speeds the clean-up process. Always remove the excess cement before complete setting.
