KATANA™ Zirconia YML a été développé sur le principe de reproduction de la réalité, qui exprime alors précisément et naturellement la couleur et la translucidité de la dent naturelle.
Pour fournir une haute translucidité en harmonie avec les dents antérieurs.
Pour fournir une transition fluide de la couleur et translucidité vers la couche d'émail.
Pour fournir une couleur profonde et vive tout en réduisant le blanchiment.
Une remarquable flexibilité de conception est possible - des facettes aux restaurations d'arcades complètes. Dans chaque cas, vous pouvez choisir une conception monolithique, réduite ou armatures avec la procédure de fabrication appropriée en fonction des besoins individuels.
Avec sa composition en différentes couches et des valeurs CTE stables sont obtenus en contrôlant l'ensemble du processus, du raffinage au moulage. Un contrôle qualité approfondi, associé à des matières premières uniques développées en interne, permet d'obtenir la meilleure zircone de tous les temps.
Nous nous distinguons par cette production interne unique de matériaux à base de zircone. Il garantit un matériau sur lequel vous pouvez toujours compter.
KATANA™ Zirconia YML et STML sont présentés ci-dessous avec une épaisseur de couche de dentine ajustée à 0,4 * mm pour YML et à 0,8 * mm pour STML. La couche de dentine de YML peut être ajustée plus fine que celle de la zircone à haute translucidité, augmentant encore plus sa translucidité.
KATANA™ Zirconia YML présente des marges nettes et moins d'écaillage, ce qui permet un meilleur ajustement des marges. Des restaurations plus minces montrent que ce bon résultat en marge nette soutient l'utilisation de KATANA™ Zirconia YML.
Même si les marges de la restauration ont été fraisées très fin, elles présentent toujours des marges lisses sans aucun écaillage.
La qualité exceptionnelle associée à la vitesse est une caractéristique unique absolue de KATANA™ Zirconia par rapport à tous les produits concurrents.
Ces recommandations de sintérisation sont seulement un guide, quelques ajustements peuvent être requis en fonction de chaque four.
Si les programmes en 54 ou 90 minutes ne sont pas programmables sur votre four, il ne sera pas possible de sintériser.
Choisissez la teinte cible et la bonne épaisseur de disque pour obtenir une
graduation appropriée entre la longueur de la couronne, l'émail et la dentine.
KATANA™ Zirconia YML doit être sélectionnée en prévision d'un glaçage. En cas de polissage, elle a tendance à devenir une teinte plus foncée. Il faut donc choisir une teinte plus claire que la teinte cible.

Nous avons rassemblé une liste de réponses aux questions les plus pertinentes.
The existing KATANA™ Zirconia multi-layered materials (KATANA™ Zirconia UTML/ STML/HTML) have a color gradation, while the base material of the respective type is the same for all layers. The strength and translucency are the same for all layers of the respective type.
KATANA™ Zirconia YML is different in this regard. It is the latest KATANA™ multi-layered disc with a balanced combination of color/translucency and flexural strength gradation. Please refer to chart below, for the overview of the mechanical properties and translucency levels of each type of KATANA™ disc.
“All-In-One” means all application range with one disc. KATANA™ Zirconia YML is characterized by a unique raw material combination of highly translucent zirconia with high strength, which are integrated together by an advanced manufacturing technology. As an “All-In-One” solution, KATANA™ Zirconia YML offers exceptional design flexibility, from long-span full-arch monolithic bridge restorations up to highly aesthetic anterior monolithic crown restorations.
From complicated full-arch restorations to highly aesthetic demanding anterior single-unit restorations, an exceptional design flexibility is available. In each of these cases, you can choose a monolithic, cut-back or framework design with the appropriate fabrication process, depending on your specific needs.
Framework
Long span bridge
Anterior / posterior crown
Inlay, onlay
Laminate veneer
KATANA™ Zirconia is characterized by the unique in-house production of zirconia raw materials. By using materials that Kuraray Noritake Dental Inc. has developed themselves specifically for the KATANA™ Zirconia series, completely different from those of other competitors, it is possible to realize high-speed sintering without compromising the aesthetic and mechanical properties.
KATANA™ Zirconia YML is available in a shade selection of 14 shades, which are adapted to the VITA-classical A1-D4™ Shade Guide. Please refer to the following table overview for more information about shape and disc-thickness.
Shade / Thickness selection
Please observe the following guidelines of applicable minimum wall thickness:
The thickness specifications apply to full zirconia restorations. The thickness of build-up porcelain is not included. The minimum wall thicknesses apply to full zirconia restoration or to frame-work for build-up porcelain restoration. In these cases, 0.4 mm (anterior) or 0.5 mm (posterior) should be kept for the area located in the bottom (lower) half of the disc. If full zirconia veneer restoration is used for combination with the porcelain, 0.8 mm or more should be kept for the area located in the upper half of the disc.
Please observe the following guidelines of applicable cross-section wall thickness:
3 units or less Connector cross-section area can be placed in any layer.
A
The maximum number of pontics is one. Not suitable for a cantilevered bridge. 4 units or more - at least 50% of the connector cross section should be positioned in the bottom (lower) half of the disc.
B
The maximum number of pontics between two abutments (teeth) should not exceed two. For cantilever bridge, keep the number of pontics at one. In this case, the connector cross-section must be at least 12 mm.
Please observe the following of sintering schedule:
The above sintering recommendations represent only a guideline; depending on each individual furnace and condition, some adjustments might be necessary. If the 54 or 90-minute sintering program is not programmable in your furnace, it is not possible to set the furnace according to one of these schedules.
No, this is not possible. 54- or 90-minute sintering is only possible for up to a three-unit bridge restorations.
The body layer has a higher content of tetragonal crystals, while the cubic content gradually increases towards the enamel layer.
KATANA™ Zirconia YML can be finalized by glazing, staining or porcelain application. With an integrated translucency, color and strength gradient, KATANA™ Zirconia YML is designed to achieve highly aesthetic results by simply using the glazing technique. In case of additional color adjustments, characterizations or individualizations are desired, the unique CERABIEN™ ZR (CZR) FC Paste Stain can be used to achieve the final high aesthetic result according to your preferences.
Of course, this is possible. For this purpose, the desired high-polished finishing can easily be achieved with the PEARL SURFACE™ Z (polishing paste). Please note that the shade of KATANA™ Zirconia YML should be pre-set for glazing, due to the fact that zirconia has a tendency to become darker during the polishing process. Therefore, select in advance one shade lighter than the target shade.
It is generally not recommended to wet-mill KATANA™ Zirconia, because the desired aesthetic effect may not be achieved due to the possibility of contamination, which can reduce the translucency.
If a restoration is contaminated before sintering, it will cause white spots on the restoration during the sintering process. Causes for this are for example oily fingers, excessive purging with high air pressure, residuals of silicon point substance that has been applied to the pre-sintered zirconia during adjustment procedures, the use of scanning spray, or the insufficient removal of zirconia powder that has been created during the milling process/removal of sprue. Please take care not to contaminate the restoration.
This is not recommended, as the desired level of translucency or color development cannot be achieved.
The sintering parameters differ from other manufacturers’ zirconia products. The maximum sintering temperature for the 54-minute program is 1600°C (2912°F), for the 90-minute program 1560°C (2840°F) and for the 7-hour program 1550°C (2822°F).
Note: The material is removed from the furnace at 800°C. High-speed sintering is possible for up to three-unit bridge restorations.
Any sintering furnace capable of setting the KATANA™ Zirconia YML sintering program according to its technical specifications can be used, regardless of the manufacturer. If the KATANA™ Zirconia YML sintering program is not programmable in your sintering furnace, it is unfortunately not possible to set the furnace according to this schedule.
Yes, this is possible using several options in your CAD/CAM software. These options allow the designer to change the restoration position within the disc profile to achieve the best gradation map for the restoration. Please refer to our “Handy Chart” as a guideline for this.
