Vitality Layered Zirconia
Vitality Layered Zirconia combines the esthetics your patients demand with the strength and affordability you desire. Lab tests have shown the fracture toughness and flexural strength of zirconia are significantly higher than that of alumina or any other all-ceramic. With Vitality Zirconia there is no metal to show through the ceramic and no unsightly black lines at the gingival margin.
This esthetic restoration is built on a coping composed of zirconium oxide, one of the strongest and most biocompatible ceramic materials. After being milled using CAD/CAM technology, the final restoration achieves superb intimacy of fit and beautiful, translucent pearlescence.
Vitality Layered Zirconia is indicated for individual crowns, splinted crowns and bridges up to 14 units anywhere in the mouth. Conventionally cement with resin ionomers.
Indicated for anterior and posterior single-unit crowns and multiple-unit bridges spanning up to 14 units. Indicated for full contour crowns, inlay or wing-type bridges, with up to a two-pontic span.
Anterior full-coverage crowns require a chamfer with 1.5 mm facial reduction, 1.5 mm lingual contact clearance, 1.5 mm incisal reduction 1.25 mm reduction at the gingival margin with rounded internal line angles; or a shoulder with 1 mm lingual reduction, 2 mm incisal reduction, 1.5 mm labial reduction, 1 mm 360° rounded shoulder.
Posterior full-coverage crowns require a chamfer margin with 2 mm occlusal reduction, 1.5 mm buccal and lingual reduction with rounded internal line angles; or a shoulder with 2 mm occlusal reduction, 1.5 mm buccal and lingual reduction and 1.25 mm gingival margin reduction with rounded internal line angles.
