Full Contour Zirconia:: The strongest metal-free restoration available, the full zirconia is quickly becoming one of the most popular crowns around. We offer the standard version (1000-1250 MPa average), recommended mainly for posterior restorations. We also offer a more translucent version that is more beautiful, but slightly lower strength (700 to 765 Mpa average). Also try our 3/4 Zirconia occlusal with a layered porcelain face for the best in strength and esthetics. All of our full contour zirconia restorations are finished with our usual unmatched precision and attention to detail that will save you precious chair time.
