Description
High-fusing porcelain for all common porcelain-bonding alloys with a CTE range from 13.5 to 14.6 x 10⁻⁶K⁻¹ (25 to 500 °C). The ceramic system with a natural dispersion and reflexion of light (Halo effect) has been developed over several years in cooperation with Makoto Yamamoto. Computer-controlled shade measurements of several thousand natural teeth have led to a new definition of the dental shade spectrum and its expansion to altogether 38 shades.
The 16 shades have been expanded:
• Root shades: chroma intensive for the A, B, C shade group;
• Red Shift shades: reddish, the so-called 5th shade group;
• Value Plus shades: with an increased brightness value.
