Porcelain fused to zirconia restorations are an excellent alternative to PFM restorations. With a high flexural strength, they are hypoallergenic and biocompatible. Crafted by layering feldspathic porcelain over a zirconia substructure, they provide the strength of PFM crowns while eliminating esthetic challenges, such as bright opaque reflection or the dark shadow line that can appear apical to the margin. Through the use of advanced CAD/CAM technology, they provide consistently accurate fit. Due to zirconia’s natural translucency, these crowns are warmer and provide superior lifelike coloration when compared to their PFM counterparts.
A CAD/CAM substitute for traditional PFM, our porcelain-fused-to-zirconia can be used for anterior and posterior crowns, crowns over implants, and bridges of up to eight units.
The ideal margin preparation for a PFZ is a chamfer. With corresponding prep depth the idea crown thickness is 1.5 mm axial and 2.0 mm occlusal or incisal.
The manufacturer Ivoclar Vivadent recommends using Multilink Automix for maximum strength of the restoration over-all.
If an adjustment is required on the ceramic, use a fine diamond with water and air to keep the crown cool.To polish the roughened the ceramic, use the Brasseler Dialite Polishing System or similar substitute.
