Resin-Reinforced Glass Ionomer Cement

UltraCem resin-reinforced glass ionomer cement is available in a traditional hand-mix bottle kit, an economical choice that gives clinicians control over the amount of material used. Its advanced chemistry boasts the highest bond strengths in its category1 while ensuring the ultimate luting convenience.

UltraCem cement is used as a luting cement for indirect restorations (including inlays, onlays, crowns, and bridges) made of metal, porcelain fused to metal, zirconia, and resin. It may also be used for cementation of orthodontic bands.

  • Strongest RRGI/RMGI tested1
  • Sustained fluoride release1
  • Flowable viscosity and low film thickness won't compromise fit or occlusion1
  • UltraCem is more retentive than other leading RMGI cements on precious alloy crowns2
  • Ionic bonding to tooth structure
  • 1– to 3–minute working time, 5–minute set time
  • Radiopacity > 1 mm aluminum

Note: Never use phosphoric acid to clean zirconia, as it will significantly reduce bond strengths. Do not use a zirconia primer with UltraCem cement.

Technical Details

Strongest RRGI/RMGI tested


Available in a Hand-Mix Bottle Kit

UltraCem RRGI cement can be purchased in a traditional hand-mix bottle kit. This allows the clinicians to control the viscosity of the cement as well as the amount of material used.

Sustained Fluoride Release

The fluoride-releasing chemistry of UltraCem RRGI cement helps to minimize post-op sensitivity and provides caries-prone patients additional protection against decay.


Frequently Asked Questions

  • Can I use UltraCem cement for zirconia restorations?

    Yes. Apply Peak Universal Bond adhesive to the preparation using a scrubbing motion for 10 seconds. (No etchant is required.) Aggressively air thin until the surface appears dull and light cure for 10 seconds with VALO LED curing light. For best results, sandblast the inside of the zirconia prosthesis; clean with air/water spray, and dry.

  • Can I use a zirconia primer with UltraCem cement?

    Never use phosphoric acid to clean zirconia, as it will significantly reduce bond strengths. Do not use a zirconia primer with UltraCem resin-reinforced glass ionomer cement.

  • What is the working time and set time of UltraCem resin-reinforced glass ionomer cement?

    Working time is between 1-3 minutes. At about 3 minutes, UltraCem cement will start to cure and become more gel-like. This is the stage where removal of excess cement around the prep is the easiest.  UltraCem cement will be fully set in the mouth in 5 minutes. Note: UltraCem cement will set up less quickly on a mixing pad than in the mouth.

  • How does UltraCem cement achieve such high bond strengths compared to other RRGI Cements on the market?

    UltraCem cement’s formula contains polyacrylic acid, which is self-etching. Longer setting time is needed for it to effectively etch the tooth surface, thus yielding the higher bond strengths.
