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.


With GRADIA DIRECT composites, you can take your time crafting the most beautiful restorations possible. According to the manufacturer's website, the GRADIA DIRECT family of premier composites:


• Employs the latest in micro and nano technologies 
• Offers unmatched handling 
• Features natural, lifelike coloring and characteristics 
• Blends into the surrounding tooth structure to create stunning restorations 
• Allows 90% of restorations to be done with only one shade 
• Is brushable and not sensitive to ambient light

Handling  

GRADIA DIRECT provides superior handling capabilities, with anterior shades that sculpt readily and posterior shades that offer exceptional strength and body. With plenty of working time, even in ambient light, its non-stick formula allows you to easily sculpt, shape and contour with unmatched artistry and precision.

Beauty

GRADIA DIRECT attains natural reflectivity through the use of a multifaceted tooth-like particle structure, providing your restorations with true-to-life color while rendering them virtually undetectable compared to other restoratives. 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 that replicate that of natural teeth.

Single Shade Simplicity

RADIA DIRECT is so easy to use that 90% of restorations can be completed with just one shade. GRADIA DIRECT not only picks up the color and matches the surrounding teeth, it becomes esthetically “invisible” compared to other restoratives.
