Katana ZR YML 18 mm

Description

Kuraray Noritake KATANA Zirconia YML is a pre-shaded multilayer zirconia for the fabrication of aesthetic and durable all-ceramic restorations. The material combines high strength in the lower part of the disc with increased translucency towards the enamel region and can be used for restorations ranging from thin veneers to extensive bridges.

Product facts

• Type: Pre-shaded multilayer zirconia with strength and translucency gradients
• Material: Yttria-stabilised zirconium oxide

• Layer structure: Seamless progression of shade, translucency and flexural strength
• Flexural strength: Up to approximately 1,100 MPa in the lower part of the disc
• Translucency: Up to approximately 49% in the incisal region
• Shades: 13 classic A–D shades and NW
• Format: 98.5 mm discs
• Size: 98.5 × 18 mm
• Applications: Anterior and posterior restorations
• Restoration options: Monolithic, cut-back or as a framework for ceramic veneering

Benefits

The combination of high strength and high translucency within the same disc provides a very broad range of indications. The stronger lower section offers stability for bridges and extensive constructions, while the more translucent upper section supports natural and aesthetic results in the anterior region.

Shade and aesthetics

The seamless multilayer structure creates a natural transition from a more chromatic dentine region to a lighter and more translucent enamel region without visible transition lines. The vertical position of the restoration within the disc affects the distribution of shade, translucency and strength in the completed restoration.

Applications

Suitable for veneers, inlays, onlays, anterior and posterior crowns, short-span bridges, multi-unit bridges, full-arch restorations and ceramic frameworks. For bridges of four or more units, a sufficient proportion of the connectors must be positioned within the stronger lower half of the disc.

Processing

The material is supplied in a pre-sintered state and is milled in a compatible dental CAD/CAM system. After sintering, the restoration can be polished, stained and glazed or individualised with compatible CERABIEN ZR materials. Speed-sintering programmes of approximately 54 or 90 minutes can be used for approved restorations of up to three units, while larger constructions require a longer sintering programme.
