3M ESPE RelyX Luting Plus Automix is a radiopaque, fluoride-releasing, resin-modified glass ionomer luting cement. It is self-curing with an option for tack light curing of excess cement for ease of removal. It consists of base and catalyst pastes packaged in an automix syringe. It is available in a white shade. 3M ESPE RelyX Luting Plus Automix is indicated for the permanent cementation of ceramic-metal (PFM) crowns and bridges; metal crowns, inlays and onlays; crowns made with alumina zirconia cores; posts; and orthodontic bands and appliances. 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. The trial kit includes one 8.5 g syringe of cement with 12 mixing tips. 3M ESPE RelyX Luting Plus Automix was evaluated by 32 consultants in 580 uses. It received a 96% clinical rating.

Product Features

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.

Clinical Tips

  • 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.
