Ultra-Translucent Multi-Layered zirconia is the industry’s leading all-ceramic restorative material. Available in a full variety of multi-layered colors with the highest possible translucency, UTML reaches esthetic levels never before reached by all-ceramic restorations. Ideal for anterior crown or veneer restorations, UTML achieves that high level of translucency required for a natural look with surrounding teeth and prevent noticeably white and unnatural appearance. Suitable for treating cases in which it is desirable to utilize abutment color to enhance final results.
A highly versatile zirconia, 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.

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 KUTML 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.
