Zirconia


nexxzrtpageheader

Mabel Dental Lab has chosen SageMax out of Washington state and their NexxZrT as our Zirconia of choice. This high quality Zirconia offers great esthetics, strength and versatility. Its translucent levels are the highest of all zirconia tested. The monolithic crown is milled from a single block and so a Zirconia crown can be up to 5 times stronger than a porcelain fused to metal (PFM) crown! It is glazed with a smooth surface but designed specifically for the posterior with more emphasis and strength than beauty. Our Zirconia has received a 5 Star Rating from “The Dental Advisor” in a long term clinical study. To read more click on the chart below.
