Esthetic Colorant – first impressions by Francesco Napolitano
As an instructor and consultant for Kuraray Noritake Italia, I received my first set of Esthetic Colorant dyeing liquids for testing purposes approximately one year ago. When the package arrived in the dental laboratory, it made me curious immediately and I simply could not wait to start using the colourful liquids on KATANA™ Zirconia.
I started with some simple test work, applied the basic liquids like A Plus to pre-sintered zirconia, played a little with Gray and Violet and put the structures into the sintering furnace to reveal the obtained effects. The outcome was so convincing that I was sure Esthetic Colorant would be a great addition to the range of materials used in my laboratory for the production of zirconia restorations. The liquids would support me ideally by giving more character to my restorations from the inside.
To my mind, the use of Esthetic Colorant is convenient for two reasons:
- KATANA™ Zirconia is a very compact material, even in its green (pre-sintered) state. This property is not only responsible for a great performance in terms of milling accuracy, stability and surface quality, but also provides for a controlled penetration of the effect liquids into the structure. They neither diffuse too deep into the zirconia nor do they spread too much on the surface.
- Esthetic Colorants are water-based infiltrating liquids with a very light colour effect. Hence, they do not create such marked characterization effects like liquids from other companies. This is a huge advantage in my eyes, because I can characterize my zirconia internally without exaggerating. This allows me to copy lightly to moderately intensive effects, while giving depth to some areas of the tooth. Great examples are the occlusal table of a posterior restoration or incisal effects in the anterior region. In addition, I am able to shield the grayish effect resulting from a metal post or discoloured abutment tooth with the Esthetic Colorant Opaque applied to the inner surface of a restoration.
In short: I think Esthetic Colorants are fantastic. Just try them out yourself, because seeing is believing!
