Porcelain fused to zirconia crowns are a natural-looking restoration well-suited for use on anterior teeth. Their zirconia substructure and porcelain exterior helps to imitate the esthetics of a real tooth. The zirconia substructure is layered with porcelain to mimic natural teeth using the excellent translucent property of Feldspathic porcelain, without sacrificing function.

Zirconia restorations can be placed using adhesive systems with dual cure resins (RelyX Unicem, 3M ESPE; Panavia SA Plus, Kuraray. We recommend Z-PRIME from BISCO to prepare the inside of the crown for adhesive dentistry) or cemented using low expansion cements, like resin-modified glass ionomers, (RelyX Luting Cement, 3M ESPE; GCFuji Plus, GC America)
