Abstract
PURPOSE. Zirconia has been used in clinical dentistry for approximately a decade, and there have been several reports regarding the
clinical performance and survival rates of zirconia-based restorations. The aim of this article was to review the literatures published from 2000
to 2010 regarding the clinical performance and the causes of failure of zirconia fixed partial dentures (FPDs). MATERIALS AND
METHODS. An electronic search of English peer-reviewed dental literatures was performed through PubMed to obtain all the clinical studies
focused on the performance of the zirconia FPDs. The electronic search was supplemented by manual searching through the references of
the selected articles for possible inclusion of some articles. Randomized controlled clinical trials, longitudinal prospective and retrospective cohort
studies were the focuses of this review. Articles that did not focus on the restoration of teeth using zirconia-based restorations were
excluded from this review. RESULTS. There have been three studies for the study of zirconia single crowns. The clinical outcome was
satisfactory (acceptable) according to the CDA evaluation. There have been 14 studies for the study of zirconia FPDs. The survival rates of
zirconia anterior and posterior FPDs ranged between 73.9% - 100% after 2 - 5 years. The causes of failure were veneer fracture, ceramic core
fracture, abutment tooth fracture, secondary caries, and restoration dislodgment. CONCLUSION. The overall performance of zirconia
FPDs was satisfactory according to either USPHS criteria or CDA evaluations. Fracture resistance of core and veneering ceramics, bonding
between core and veneering materials, and marginal discrepancy of zirconia-based restorations were discussed as the causes of failure. Because
of its repeated occurrence in many studies, future researches are essentially required to clarify this problem and to reduce the fracture incident.
