Exceptional Translucency ZR.

SpectraMax™ is Bristol Crown’s latest zirconia with exceptional translucency! Introduced in 2014 our SpectraMax™ crowns have proved to be hugely popular. It is particularly suitable for the anterior tooth region but can be used anywhere in the mouth. We can do single crowns, inlays, onlays and bridges with a maximum of 3 units.

These can all be fully anatomic or reduced for porcelain addition. We use Exocad software for our SpectraMax™ Crowns which we believe has the best library of occlusals available.

Exceptional Translucency

SpectraMax™ offers exceptional translucency, making it particularly suitable for the anterior tooth region.

SpectraMax™ is zirconia without glass. It contains about 6 mol% Y2O3 (Yttrium) instead of 3 mol% Y2o3 for normal dental zirconia. It contains around 50% tetragonal phase and 50% cubic phase.

Because the cubic phase is more translucent and has lower strength, the SpectraMax™ has a lower strength, around 600MPa, and a high translucency of 49%.

Furthermore, SpectraMax™ medical grade Zirconia is fully biocompatible and isostatic.
