Zirconium-based restorations are becoming a part of the restorative armamentarium. Anecdotal evidence, in vitro studies, and clinical results support their use within certain parameters. This presentation discusses how the unique properties of zirconium affect the clinical handling and the indications and limitations of these restorations and how the advent of CAD/CAM technology supports their fabrication.
