Katana™ Zirconia crowns are born from multi-layered pucks created specifically for fabricating the most natural looking restorations with strength beyond what is possible with the original tooth. Available in full-color variation in high translucency, it produces the highest esthetic level restorations for all indications.
Katana
The Katana™ UTML creates a high-quality full contour zirconia restoration, ideal for anterior crown, veneer and inlay/onlay restorations. The enamel shades have reduced chroma in the upper layer, allowing your to create the most lifelike color matching, and a 550 MPa flexural strength.
The Katana™ STML is milled from a shade-matching puck, making it highly esthetic and functional. STML is perfect for anterior or posterior crowns.
A highly versatile zirconia, Katana UTML is indicated for Ideal for anterior crowns and veneers, inlays/onlays and posterior single crowns.
Shoulder preparation not needed. A mild champfer or a feather edge margin is good. 1mm buccal, lingual and occlusal reduction is ideal, but can go to .5mm in some areas, when reduction is limited.
Minimum occlusal reduction of 0.5 mm; 1 mm is ideal.
Adjustments and polishing: Adjust zirconia crowns and bridges using water and air spray to keep the restoration cool and to avoid micro-fractures with a fine grit diamond. If using air only, use the lightest touch possible when making adjustments. A football-shaped bur is the most effective for occlusal and lingual surfaces (on anterior teeth); a tapered bur is the ideal choice for buccal and lingual surfaces.
Polish zirconia restorations with the porcelain polishing system of your choice.
Katana UTML zirconia may be cemented using a resin reinforced glass ionomer such as Relyx Luting cement. When a greater bond is needed do to the lack of a retentive preparation, use resin cement like Relyx Unicam or Relyx Ultimate.
Before cementing all Katana UTML zirconia crowns, the interior surface of the crown needs to be cleaned with Ivoclean (Ivoclar Vivadent; Amherst N.Y.). This is critical in assuring maximum bond strength.
Pearl Surface Z is a diamond paste ideal for polishing the zirconia surface to a final finish on Full Contour Zirconia Crowns. Specially developed for Katana zirconia, it is the simplest and fastest way to achieve finished Full Contour Zirconia Crowns.Polish solid zirconia restorations with the porcelain polishing system of your choice.
