About Giomer Request Info
The term “Giomer” refers to any product containingShofu’s proprietary Surface Pre-Reacted Glass, or “S-PRG” filler particles. S-PRG filler uniquely releases 6 ions: Fluoride, Sodium, Strontium, Aluminum, Silicate, and Borate; S-PRG filler has been shown to inhibit plaque formation, and possess remarkable acid neutralization capabilities.
Demonstration of S-PRG Filler Neutralizing Lactic Acid on Contact:
Unlike glass ionomers and compomers which require water absorption following photocure to release fluoride; Giomers contain a multifunctional glass core that undergoes an acid-base reaction during manufacturing and is subsequently protected by a surface modified layer.
Anatomy of S-PRG:
Shofu’s proprietary Giomer technology, surface pre-reacted glass (S-PRG) filler is a bioactive, trilaminar structure which forms a type of stable glass ionomer allowing ion release and recharge, while protecting the glass core from the damaging effects of moisture, greatly improving long-term durability. This unique Giomer chemistry is therefore able to achieve ion uptake from household dental hygiene products such as toothpaste, providing sustained benefits to adjacent tooth structure over the life of the composite.
S-PRG filler material has been clinically shown to:
• Recharge fluoride when treated with fluoridated products
• Neutralize acid on contact
