Laboratory aspects of zirconia restorations

Zirconia restorations are now accepted and commonly prescribed in dentistry. However, these materials undergo hydrothermal ageing which can reduce their clinical performance. Appropriate handling is essential to limit the restorations' susceptibility to low temperature degradation/ageing. Through appropriate clinical prescribing and laboratory manufacture, an aesthetic, strong and long-lasting restoration can be fabricated. Clinical Relevance: This article will inform the reader about zirconia as a dental material as well as how best to handle a zirconia restoration.
