GRADIA™ DIRECT
Light-Cured Microfilled Hybrid Resin Composite
Light-cured
GRADIA DIRECT is a micro-filled hybrid resin composite with microfine
pre-polymer resin fillers, a unique coupling agent and urethane
dimethacrylate co-monomer matrix which offers significant advantages
in esthetics, polishability, wear resistance and fracture toughness.
Designed to
be the best enamel replacement ever, GRADIA DIRECT has tooth like
color reflection and absorption and lifelike optical properties,
including brightness, translucency and warmth.
Direct
or Indirect
Just like GRADIA (for INDIRECT laboratory restorations), new GRADIA
DIRECT has multifaceted reflective and optical properties similar
to that of natural tooth.
Esthetic
Invisibility - Single Shade Simplicity
 Easy
to complete natural looking, high-end multi-layer restorations
with as little as a one shade technique.
Picks up the
color and matches the surrounding tooth becoming esthetically “invisible.”
In fact, in
about 95% of restorative cases, GRADIA DIRECT can achieve brilliant
esthetics with only one shade.
Best
Handling Composite Ever
- Anterior
shades sculpt readily.
- Posterior
shades offer strength and body.
- Plenty
of working time even in strong ambient light.
- Not sticky,
so it shapes and sculpts easily. You can even add and take away
material with an artist’s brush.
Clean
and Simple Shade System Complete direct restoration system
features 26 shades. Choice of Unitip or Composite Syringe delivery.
Standard
Shades (11 anterior; 4 posterior), for most simple restorations
just one single shade technique gives excellent results.
Special
Shades for more extensive multi-shade techniques; placed
underneath or on top of a Standard shade.

Inside
Special Shades (3 anterior shades) are opaque shades
placed underneath a Standard Shade to give warmth to the final
color and block out unwanted dark color.
 Outside
Special Shades (6 anterior; 2 posterior) are placed on
top of a Standard Shade, to adjust for age-related changes in
the enamel - translucency and value - to give a more lifelike
appearance.
Great
Physical Properties
- Provides
outstanding esthetics without sacrificing strength, durability
and longevity.
- High fracture
toughness.
- Low modulus
of elasticity to resist bending and cracking from occlusal forces.
- High Wear
Resistance for posterior restorations, GRADIA DIRECT is very
durable, exceptionally resistant to occlusal wear, yet kind
to opposing dentition.
Light
Curable: Can be cured using a quartz halogen curing light,
a plasma arc curing light or LED (Light Emitting Diode) Light.
Color
Stable: Very color stable before and after light-curing.
Superior
Finish: GRADIA DIRECT can be highly polished with minimal
effort.
Particle
Structure Mimics Reflectivity of Natural Tooth:
Designed to
mimic the reflectivity of natural tooth structure. GRADIA DIRECT
blends in and picks up the color of the surrounding teeth. 
Made up of
diverse, multifaceted structures - a variety of particles consisting
of a micro filled matrix of resin composite, with compounds mainly
of silica, pre-polymerised fillers and urethane dimethacrylate
co-monomer matrix.
The amount
of each element and its particle size distribution has been carefully
chosen so that when added together, many different interfaces
occur with different reflective properties. The result is internal
reflectivity and optical properties which replicate that of natural
teeth.
Natural
Reflectivity Means Natural Esthetics:
Toothlike
reflectivity makes restorations appear natural, with true to life
color and full vitality.
GRADIA DIRECT
restorations are esthetically “invisible” when compared
to other restoratives.
Single shade
simplicity for most restorations.
Natural looking
high end multilayer restorations for more intricate cases are
easy to complete.
