PRISMATIK CLINICAL ZIRCONIA

13 November 2014
Author :  

Prismatik Clinical Zirconia™ combines the esthetics your patients demand with the strength and prismatik clinical zirconiaaffordability 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 Prismatik CZ, designed by our R&D team, 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.

Prismatik CZ is indicated for individual crowns, splinted crowns and bridges up to 14 units anywhere in the mouth. Conventionally cement with resin ionomers.

INDICATIONS

Prismatik Clinical Zirconia is indicated for anterior or posterior crowns and multiple-unit bridges.

BENEFITS FOR THE PATIENT

Medical grade zirconia is completely biocompatible, and its metal-free substructure allows for beautiful esthetics. Flexural strength of the Prismatik CZ is >1200 MPa.

PREP REQUIREMENTS

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 1.0 mm lingual reduction, 2.0 mm incisal reduction, 1.5 mm labial reduction, 1.0mm 360 degree rounded shoulder.

Posterior full-coverage crowns require a chamfer margin with 2.0 mm occlusal reduction, 1.5 mm buccal and lingual reduction with rounded internal line angles; or a shoulder with 2.0 mm occlusal reduction, 1.5 mm buccal and lingual reduction and 1.25 mm gingival margin reduction with rounded internal line angles. Chamfer Margins — Correct preparation of the chamfer margins interproximally allows the appropriate bulk of porcelain.
