Innovation demand

Despite the use of complex layering techniques combining different shades and opacities of resin composite, the transition from composite restoration to tooth structure often remains visible in direct restorations. In order to promote a smoother optical integration, Kuraray Medical Inc. has developed its Light Diffusion Technology. Together with the right translucency, this feature makes restorations made of CLEARFIL MAJESTY™ ES composites blend seamlessly with the adjacent tooth structure. The technology is incorporated in special cluster fillers acting like millions of micro-prisms.

Key benefits

The proprietary light diffusion filler has been optimised in size and refractive index in relation to the matrix to offer unsurpassed natural shade blending. No matter whether a complex layering procedure involving different shades and opacities or a single-shade technique is used: Light Diffusion Technology provides for a great optical integration with undetectable restoration margins.
