Kuraray Noritake Dental Inc. announces the launch of Esthetic Colorant for “KATANA™ Zirconia”

A particularly chromatic cervical area, pronounced mamelons and translucencies in the incisal area: every natural tooth has its characteristic optical features stemming from its inner structure. Unfortunately, imitating these specific effects by merely adding stains or liquid ceramics to the surface of a monolithic restoration is quite hard to achieve. For this reason, Kuraray Noritake Dental Inc. introduces Esthetic Colorant for “KATANA™ Zirconia” – a set of easy-to-use shading liquids diffusing into the zirconia structure and enabling imitation of variety of internal shade structures. It is an excellent choice for creating initial characteristics of the restoration before the sintering procedure, and by doing so laying groundwork for the final fast and easy individualization.

Esthetic Colorant has been specifically developed for the “KATANA™ Zirconia” Multi-Layered Series to complement the effects obtained from the materials’ multi-layered colour structure. The system consists of twelve shading liquids, which have been optimised to maintain the original flexural strength of the “KATANA™ Zirconia” restoration. After milling, the liquids are applied to the clean surface of a monolithic or anatomically reduced restoration with a metal-free brush, preferably with our Liquid Brush Pen. The Esthetic Colorant then diffuses into the zirconia, and the desired inner shade effects are fixed and revealed after the final sintering procedure. Finishing can be accomplished through a variety of techniques including polishing, glazing and micro-layering.

The compact Esthetic Colorant line-up facilitates inventory management, while the typical effects of natural teeth can be reproduced in a predictable way. Using the new Liquid Brush Pen for Esthetic Colorant, the application procedure is streamlined, as the dental technician is given full control over the amount of shading liquid applied.
