—Create natural-looking insical area— (Made with Noritake CZR)
This is a challenging case because it’s very hard to replicate the incisal area when there’s a lot of depth and translucency. Because I’m doing extended research on how to have easier-faster-predictable results, I found out that when dentin becomes very thin 0.3mm, it also becomes translucent.
In this case, when I was building up the crown, I built up the dentine until the total length, then I made it 1 mm longer with enamel (E2) and on the mesial and distal area I used aqua blue 2.
On the insical frame, I added a little bit of mamelon 2 and I used T0 to create more depth in the incisal area and to create the dentin-enamel connection (DEC)
This was my first bake.
Then, to create the translucent incisal area and to make it look natural, I used LT0 to lengthen the incisal area and on top of this, I mixed LT0 with mamelon 2 to create a halo effect.
So, I believe that to achieve this, the process must be done in 3 phases:
1. Histo-anatomy of the dentin, incisal frame
2. Internal effects and DEC
3. Skin enamel and halo effect.
What are your thoughts on this challenge?

—I AM STILL A BEGINNER—
This is my third crown with Noritake CZR, so I am still a beginner :-P
As you can see, this case is very difficult because it has bright opacious dentine and translucent dentine. In the black and white photo it is shown that I was able to mimic that because of my calculations of the dentines before I start layering.
If we want to have a natural-looking shade match, then we must also read the L*a*b numbers of the tooth in different areas. In this case, the opacious dentine was L*76, a*5, b*17 and the translucent dentine was L*71, a*7, b*17. To achieve these numbers I used two different recipes as you can see on the first photo.
At the first bake I fired the histo-anatomy of the dentine. At the second bake I used the Internal Staining technique to mimic the cracks and the discoloration and finally, I used skin enamel LT0
The crown is not perfect, there are still things that could be corrected but this is a lesson for the next crown. I always ask myself in every case “what I can do better next time”.
—Single Central Veneer Shade Match combining eLAB with Noritake CZR on Refractory.— --Easier- Faster- Predictable-- I have created an application that I put the target L*a*b numbers of the color and it gives me a recipe of which powders to mix with each other and with which ratio to achieve the target color. (Together with my team we work very hard to make this application available for use by everyone soon. From the new year I will also start giving courses to show you how you can use my application to achieve natural results) -For the Noritake CZR users-
To achieve a bright color like in this case L*79, a*3, b*11, I put these numbers in my application and it gave me the recipe: OBA3 with modifier WHITE.
For the incisal area, because it is translucent dentine, with numbers L*75, a*3, b*12, the recipe my app gave me was: OBD4 with NW0,5B and translucent insical AUREOLA.
This was my recipe to achieve an accurate shade match.
Thank you @stephaniezellerdds for giving me the opportunity to share my very personal story.
How I started: being a refuge, who felt unworthy, and being so shy that I couldn’t even make a proper social conversation (especially with women 😁), And how I changed my whole personality and life and became an extrovert, a dating coach and a curious, thirsty for knowledge person, who travels the world to meet the Masters in dentistry, learn from them and share this knowledge with the world.
And at last, how my personal development led me to achieve my goals as a dental technician and successfully combine the elab protocol with the one bake technique and give international lectures on it.
I am also talking about rejection and how to not take it personally, how to overcome your weaknesses, how you can actually change yourself, reach your full potential and become succesful in every aspect of life.
And how you can become a better dental technician and achieve your professional goals.
And many more....
You will find my interview at the @dentaloutliers .
You will also find many other aspiring interviews from great professionals in dentistry worldwide.
I had a great time with great dental technicians and dental Masters in Tokio.
My lecture was about “The New Era of Shade Matching in Dentistry “
My brother and mentor Naoto Yuasa asked me to give a presentation because I created a “tool” with my own philosophy, that is the reason why I have these predictable results in every case I do.
I have been creating this tool for one year and now it is getting developed into an application. Since now, I had it only for my personal use, but I showed it to Naoto and he asked me to do research and include also Noritake CZR in it, and so I did and came to present the results in Tokio, the capital of new technologies.
Soon I will be able to tell you everything about this new app that gives you Easier-Faster-Predictable results.
