Prismatik Clinical Zirconia combines the esthetics your patients demand with the strength and affordable price you desire. Laboratory tests have shown the fracture toughness and flexural strength of zirconia are significantly higher than that of alumina or any other all-ceramic. Prismatik CZ is indicated for anterior and posterior crowns and multiple-unit bridges.
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. The flexural strength of the Prismatik CZ is >1200 MPa.
Prep Requirements
• Anterior full-coverage crowns require a chamfer with 1.5mm facial reduction, 1.5mm lingual contact clearance, 1.5mm incisal reduction 1.25mm reduction at the gingival margin with rounded internal line angles; or a shoulder with 1.0mm lingual reduction, 2.0mm incisal reduction, 1.5mm labial reduction, 1.0mm 360 degree rounded shoulder.
• Posterior full-coverage crowns require a chamfer margin with 2.0mm occlusal reduction, 1.5mm buccal and lingual reduction with rounded internal line angles; or a shoulder with 2.0mm occlusal reduction, 1.5mm buccal and lingual reduction and 1.25mm gingival margin reduction with rounded internal line angles.
• Chamfer Margins — Correct preparation of the chamfer margins interproximally allows the appropriate bulk of porcelain.
