A while ago Mr. Takuro Nagura of Kuraray Noritake Dental put in an appearance at the Mardent Dental Trade event in Breda to provide some practice-oriented information to the attending dental technicians about the application of CERABIEN ZR FC Paste Stain in combination with KATANA™ Zirconia. The result was a fruitful afternoon, filled with questions, insights and tips.

Those in attendance were all dental technicians with ample experience of working with KATANA™ Zirconia. Mr. Takuro Nagura was therefore able to enjoy the experience of being surrounded by a group of enthusiastic KATANA™ fans, all of whom also use Noritake porcelain and PANAVIA™ V5 to their full satisfaction. The excellent aesthetics, perfect fit and ease of use were frequently-heard endorsements in favour of the use of Kuraray Noritake Dental products.

The session began with an introductory presentation, with an in-depth focus on the technical properties of the materials, instructions for baking, shade taking and staining techniques. Then it was time for the group to get started themselves. A KATANA™ Zirconia UTML molar and front crown had been prepared for each participant, and these were then characterised by means of CERABIEN ZR FC Paste Stain. The shades A+, Grayish Blue and Reddish Brown were used as starting points.

The entire front crown was first treated with glaze, after which external stain was applied; first in a horizontal direction, whereby dentine A+ was used cervically and enamel Greyish Blue incisal. Finally, dentine A+ was also applied vertically to emphasize the marmelon structure. Mr. Nagura offered the useful tip of first scratching in the eventual necessary crack lines with a sharp instrument such as a needle, and then colouring them in with external stain.

Glaze was initially applied to the full surface of the molar too, after which external stain was applied horizontally. A+ was used for the cervical and occlusal plane, with enamel Greyish Blue for the occlusal cusps. A+ was then applied to the vertical lines, and the fissures were finally coloured in using Reddish Brown.
