Glass Ionomers Ingredients The glass should contain strontium too! (This is important) Polyacrylic acid acid Calcium fluoroalumino silicate glass base Glass Ionomers Bioavailable once called bioac/ve Inhibits plaque & bacteria w/ fluoride and ion release Can re-mineralize tooth structure Can be bulk filled! Encapsula/on makes them easier to use.
Glass Ionomer Self Cure Materials Regular set working time: 5 minutes. Fast Set working time: 3 minutes. DO NOT DESICCATE! GI s are hydrophilic! USE WATER on Instrument to manipulate. Late over-manipulation can reduce cohesive strength of self cure materials. Glass Ionomer Self Cure Materials Finishing tips: o o o Immediately apply a VARNISH (blow dry) or an Unfilled Resin (light cure) Finish with water spray - superfine diamond bur, silicone point and polishing strips After final set, seal with a VARNISH or an Unfilled Resin (light cure) to prevent initial sensitivity to moisture and for additional acid and wear resistance Introducing EQUIA Forte
Improvements to EQUIA Forte EQUIA Forte: Same benefits as EQUIA. Due to improved physical properties, EQUIA Forte extends the indications to include full Class II restorations. EQUIA Forte Coat is available as a 4 ml bottle and a NEW 50 unit dose pack (0.1mL each). Brand new red packaging. EQUIA Forte Fil: Glass Hybrid Innovation EQUIA Forte Traditional GI Structure Highly reactive Fluoro-alumino-silicate fillers (<4μm): Helps to release more metal ions which improves the cross-linking of polyacrylic acid, to improve physical properties Higher molecular weight polyacrylic acid: Cement matrix made stronger and more chemically stable. Leads to higher flexural strength. EQUIA Forte Coat: Innovation (contd.) Newly adopted monomer Improved efficiency of polymerization Low viscosity provides thinner film layer Smoother final restoration surface

London, UK, May 2015. The graph above shows that when the coating is removed (simulating clinical situation that coat wears off) from the top surface of EQUIA Forte Fil after 30 days, there is a substantial increase in the hardness of GI due to secondary maturation. Per in-vitro tests, coat remains on the GI for more than 6 months.
Non Flow 00 67% Fill Low Flow 03 67% Fill Why are S-PRG Fillers Important? They Form A Film-like Surface Which Appears To Inhibit Plaque Forma/on Releases And Recharges Fluoride (Like A Glass Ionomer) This Is A Giomer = Stable Phase Of Glass Ionomer
Functions of Glass-ionomer phase in S-PRG Filler 1) Various Ion Release 2) Fluoride recharge 3) Acid Neutralization Effect Beautifil II LS (Low Shrink) Giomer composite with the lowest polymerization shrinkage and shrinkage stress
