Unique characteristics of GI

1
Unique characteristics of GI

• Acid Base Reaction
• Initiates - curing mechanism
• - bonding process
• - fluoride release
• Creates - hyper-mineralized zone at tooth
  interface (hybrid zone)

2
Unique characteristics of GI

• Indications
• Geriatric and Pediatric Restorations
• Final Restorations in Low Stress Areas
• Emergency Restorative (Intermediate)
• Caries Control Restorations (Min. Intervention)
• Core Build-Up or Dentin Substitute
• Long Term Temporary Restoration

GC Fuji IX GP FAST and GC Fuji IX GP Regular
Set

• Surface Hardness
• 1 Hour 51 Hv for Fast 45 Hv for Regular Set
• 24 Hr 74 Hv for Fast 74 Hv for Regular Set

4
Comparative Bonding Process

• Glass Ionomer
• Ion exchange
• Chemical Bond
• Hyper-mineralized zone
• No primer required

• Composite / Compomer
• Etching demineralizes
• tooth
• Multiple primer steps
• Mechanical Bond

5
Comparative Fluoride Release

• Glass Ionomer
• Acid base reaction caries fluoride into tooth -
  uptake
• Rechargeable
• Zone of Inhibition
• Remineralization

• Composite-Compomer
• No acid base reaction
• No ion exchange
• Primer is fluoride barrier
• No uptake

6
Benefits of Glass Ionomer

• Direct Bond to tooth - no bonding agent required
• Bonds to moist tooth
• Fluoride protection
• Excellent marginal seal - no shrinkage
• Thermal expansion tooth
• Biocompatable - Ideal match for dentin

7
Components of Glass Ionomer

• Fluoro-alumino silicate glass particles
• Complex acids
• Resin components

8
Fuji IX GP Glass Ionomers

• Resin Reinforced GI
• Packable GI
• Maintain all conventional GI benefits
• Improved performance
