GRADIA® DIRECT
Light-Cured, Microfilled Hybrid Composite Resin

GRADIA DIRECT is a light-cured, micro-filled hybrid resin composite with microfine pre-polymer resin fillers, a unique coupling agent and urethane dimethacrylate co-monomer matrix. This product offers significant advantages in aesthetics, polishability, wear resistance and fracture toughness. Designed to be the best enamel replacement ever, GRADIA DIRECT has tooth-like color reflection, absorption and life-like optical properties including: brightness, translucency and warmth.
- High fracture toughness
- Can be highly polished with minimal effort
- Exceptional color stability before and after light-curing
- Provides outstanding aesthetics without sacrificing strength, durability and longevity
- Very durable; exceptionally resistant to occlusal wear, yet kind to opposing dentition
- Can be cured using a quartz halogen curing light, a plasma arc curing light or LED (Light Emitting Diode) Light

- Superior finish
- Single shade simplicity
- High wear resistance for posterior restorations
- Plenty of working time, even in strong ambient light
- Not sticky, so it shapes and sculpts easily; material can be add or removed with an artist’s brush
- Low modulus of elasticity permits exceptional resistancy to bending and cracking caused by occlusal forces
