Indeed, the chameleon effect with the surrounding natural
teeth is so good that the restoration is aesthetically
'invisible' often with a single shade layer and gives
outstanding highend aesthetics when further shades are
used.
By studying the tooth’s optical properties it became clear that the closer a restoration
material could mimic the internal structure of a natural tooth, the closer would be
their appearance within the mouth.
To achieve this, the material of GRADIA DIRECT consists of a micro-filled matrix of resin
composite with compounds mainly of silica and pre-polymerised fillers. The amount of
each constituent 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 a diverse, multifaceted internal structure, similar to the natural tooth, which
creates an internal reflectivity that accurately reproduces the reflectivity of natural tooth.
