Perfect Solid Zirconia with a Cutback
Zirconia’s strength meets the esthetics of conventional porcelain on our Perfect Solid Zirconia with a Cutback. We mill a standard full-contour zirconia crown, then reduce the facial region to allow our ceramists to add a layer of porcelain. The result is a more lifelike restoration than conventional zirconia.
STRENGTH: 1400 MPa
Chip proof, as it is made of layered Zirconia with a porcelain overlay
Shoulder preparation not needed, feather edge is okay. It is a conservative preparation similar to full-cast gold, so any preparation with at least 0.5 mm of occlusal space is accepted. Minimum occlusal reduction of 0.5 mm; 1 mm is ideal.
Adjustments and polishing: Adjust FCZ 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 FCZ restorations with the porcelain polishing system of your choice.
