Interview: “KATANA Zirconia and CERABIEN ZR porcelain is an ideal combination”
As a dental technician with many years of experience, Björn Roland has always pursued one goal in his lab: restorations that seamlessly mimic natural dentition and possess reliable functionality. In this interview, he discusses how he integrates Kuraray Noritake Dental’s dental solutions into his daily workflow and shares some tips for creating aesthetically pleasing dental restorations.
Could you speak a little bit about your dental journey and how you were first introduced to Kuraray Noritake Dental’s range of products?
Well, I was first introduced to these products when I was in Japan about 15 years ago. I was there to undertake a course at the Osaka Ceramic Training Center of Shigeo Kataoka, but I had the opportunity during this time to attend courses conducted by Hitoshi Aoshima. Aoshima is the person primarily responsible for Noritake porcelain and who had the idea for the colouring, and he was also responsible for the idea of internal staining. I also had the opportunity to complete a course with Aoshima and visit his dental lab in Tokyo, which enabled me to begin working with Noritake porcelain when I arrived back in Germany.
You spoke at the 2019 International Dental Show about the evolution of the KATANA Zirconia range, starting with the 2013 introduction of KATANA Zirconia ML. When did you first start working with this product?
When Kuraray Noritake Dental was formed in 2012, I was lucky enough to be one of the first dental technicians to experience the multilayered technology that forms the backbone of KATANA Zirconia, to test it out before it was released to the German market. Prior to this, there had only been a monocoloured zirconia material available, which you could stain yourself by dipping it into a staining solution, but I was never a big fan of it. From the moment that Kuraray Noritake came up with its multilayered approach, I could see the potential of KATANA Zirconia—simply put, it was easy to use and had a nice and aesthetic colour shift when used for restorations.
As a dental technician, do you use KATANA Zirconia in your everyday workflow?
In our laboratory, we only use KATANA. Of course, not everything is made from the multilayered variety. We have primarily used the monocoloured KATANA Zirconia HT for the framework in the past, though we do use the multilayered option for monolithic restorations and for certain frameworks.
Do you use KATANA Zirconia in combination with CERABIEN ZR porcelain?
Yes, always. For me, it is a perfect combination. Not only are they easy to use together, but they also combine to create aesthetic restorations with great natural colour and a high level of flexural strength. In our laboratory, everyone uses CERABIEN ZR porcelain, from those who are just starting with ceramics through to the experienced and highly skilled dental technicians. Even technicians who have come from other dental laboratories and tried other porcelain materials have adapted very quickly to using it and seem to really like it. The chipping risk with CERABIEN ZR porcelain is very low, and we truly admire the brilliance of the colour.
Is CERABIEN ZR porcelain a material, in your opinion, that can benefit those with expert knowledge of porcelains?
Of course. For those who are experienced in dealing with ceramic materials and understand how they behave, they can absolutely achieve high-end results with CERABIEN ZR. It’s important to remember, though, that even dental technicians who aren’t as familiar with ceramic veneering also get good results with it—it’s not too difficult to use and get good results.
Do you use any other Kuraray Noritake Dental products in your dental lab?
Apart from KATANA and CERABIEN ZR, one product that I personally like and use from Kuraray Noritake Dental is Meister Cones, which are these small paper cones that assist with the finishing and polishing of porcelain surfaces. I brought them back with me to Germany from Japan and find them to be very handy in the laboratory.
