Resin modified |
Introduced late 1980s Composition Polycarboxylic acid polymer Flouroaluminosilicate glass Water Hydrophilic methcrylate monomer Free radical initiators Light cures |
|
|
Nanoionomer |
-Latest advancement and commercially available GIC since 2007 - material is RMGIC which there are nanomers and nanoclusters - addition of nanoparticles improve polishability and optical characterisrics of cured ionomer |
|
|
Clinical applications for GIC |
Main indications - small lesions (long term non stress bearing restorations in permanent teeth) - interim restoration of permanent teeth - excellent liner or base in all deep lesions , sandwiching or layering - class 5 restoration and abfraction lesions - direct fillin as well as core buildup |
|
|
Decreased amount of unreacted Y lead to |
Decreased strength Increased settin expansion Increased creep Decreased corrosion resistance |
|
|
Nb |
- increase mecury leads to to increase amount of y1 and y2 - decreased amount of unreacted Y |
