Precision Porcelain to Zirconia Crowns & Bridges are touted as one of the most esthetic and clinically proven all-ceramic restorations available today. These restorations offer excellent long-term stability with no allergenic potential. Milled from a presintered zirconia block, each framework is colored using one of eight VITA® shades. After sintering for 10 hours to gain strength and fracture resistance, the framework is layered with e.max fluorapatite porcelain. The final Precision restoration demonstrates exceptional marginal fit, lifelike translucency and long-term durability. Prescribe Porcelain to Zirocnia for anterior and posterior single-unit crowns, bridges up to 6 units (with a maximum span length of 55 mm), inlay bridges, wing-type bridges, implant copings and cantilever bridges.
