Unlabelled:
The search for a clinically viable all-ceramic bridge framework has been monotonous. Until recently, few materials appear to have the necessary physical and aesthetic properties. However, the development of yttrium tetragonal zirconia polycrystals, and its adoption for use in dentistry by CAD CAM technology, may hold promise as a crown and bridge framework, this being considered suitable for single and multiple units. However, to date, no long-term clinical studies have been reported. This paper describes three cases in which zirconia frameworks were used in crowns and bridges.
Clinical Relevance:
For the patient wishing to receive a non-metal crown or bridge, novel zirconia-based systems hold promise.
