Zirconia: Taking Dental Restorations to the Next Level

Since the introduction of porcelain-fused-to-metal (PFM) crowns in the 1960s, the dental industry has sought materials with both the esthetic value of porcelain, and the strength of noble metals to withstand the pressure of posterior occlusal forces.

Glass-ceramic materials that came along in the 1980s were confined to use on anterior teeth. In the early 2000s, researchers found that a toughened version of the metal zirconia met the strength requirements needed for posterior teeth, although the esthetics of the material left much to be desired.

Today, with improved technology, zirconia now rivals PFMs and all-ceramic restorations both for strength and beauty.

A member of the titanium family of metals, zirconia has multi-industry uses and is ideal for use in both anterior and posterior crowns where it fulfills functional requirements and can be custom shaded for quality esthetics.
