GC Gold Label Type 9

GC Gold Label 9 is a type 9 glass ionomer cement used as a high strength restorative for posterior teeth. It is a strontium based glass ionomer cement containing strontium glass. This provides good radiopacity and the snap-set characteristics that are highly preferred. The strontium present in the cement mimics calcium forming strontium hydroxyapatite and strontium fluoroapatite, which promote remineralization of the tooth structure from within. Gold Label 9 has a surface strengthening effect which is brought about by the diffusion of calcium ions from the saliva into the glass ionomer restorative. These glass ionomers strengthen over time in saliva. GC Gold Label 9 displays a glossy surface after mixing. This indicates the presence of sufficient polyacrylic acid to begin the ion exchange process. The movement of ions between dentin, enamel and the restorative results in chemical fusion. The seal that results from using this restorative material is consistent, predictable and long lasting. GC Gold Label 9 has desirable physical properties such as high compressive and flexural strength, high wear resistance, good radiopacity and low solubility.

FEATURES:

• Chemical adhesion to tooth structure allows minimal cavity preparation without the need for etching or bonding agents.
• Chemical setting without shrinkage allows single step placement without layering.
• Similar thermal expansion as tooth structure produce minimal stress on the marginal seal.
• Strontium based glass provides good radiopacity and snap-set characteristics unanimously preferred by clinicians.
• Strontium based fluoride releasing formulation contributes to internal remineralization within tooth structure as well as increasing surface strength over time.
