The Tetragonal-Monoclinic Transformation in Zirconia: Lessons Learned and Future Trends
TL;DR: In this article, it is shown that many of these attractive features of zirconia, especially fracture toughness and strength, are compromised after prolonged exposure to water vapor at intermediate temperatures (∼30°-300°C).
Journal ArticleDOI
Low temperature degradation -aging- of zirconia: A critical review of the relevant aspects in dentistry.
Vanni Lughi,Valter Sergo +1 more
TL;DR: A critical survey of all experimental data about the low temperature degradation of zirconia due to the tetragonal-to-monoclinic transformation shows that the main factors affecting the aging phenomenon are the stabilizer type and content, the residual stress and the grain size.
Journal ArticleDOI
Current status of zirconia restoration.
TL;DR: It is demonstrated that highly polished zirconia yielded lower antagonist wear compared with porcelains, and combined application of silica coating and/or silane coupler, and 10-methacryloyloxydecyl dihydrogen phosphate is currently one of the most reliable bonding systems for zirConia.

Novel Zirconia Materials in Dentistry
Yu Zhang,Brian R. Lawn +1 more
TL;DR: The progressive development of currently available and next-generation zirconias is reviewed, representing a concerted drive toward greater translucency while preserving adequate strength and toughness.
Journal ArticleDOI
Unstable cracking (chipping) of veneering porcelain on all-ceramic dental crowns and fixed partial dentures.
TL;DR: The central argument of this study is that residual stresses developed during the preparation of all-ceramic crowns and fixed partial dentures coupled with contact-induced cracking are the origin of the excessive chipping observed in clinical applications.

Zirconia as a ceramic biomaterial
Corrado Piconi,Giulio Maccauro +1 more
TL;DR: This review takes into account the main results achieved up to now, and is focused on the role that microstructural characteristics play on the TZP ceramics behaviour in ball heads, namely mechanical properties and their stability, wear of the UHMWPE paired to TZp, and their influence on biocompatibility.
Journal ArticleDOI
Transformation Toughening in Zirconia‐Containing Ceramics
TL;DR: In this article, a review on the science of the t-m transformation in ZrO2 and its application in the modeling of transformation-toughhening behavior, while also summarizing the microstructural control needed to use the benefits in ZRO2-toughened ceramics.
Journal ArticleDOI
Phase Analysis in Zirconia Systems
TL;DR: In this article, the content of free ZrO2 in partially stabilized zirconia ceramics by X-ray diffraction techniques was determined by linear calibration curves.
Journal ArticleDOI
Phase relationships in the zirconia-yttria system
TL;DR: In this article, the conditions for the retention of a zirconia-rich tetragonal phase at ambient temperature were established and the existence of a miscibility gap, closed below the solidus temperature, in the yttria-rich solid solution region was proposed.
Journal ArticleDOI
What future for zirconia as a biomaterial
TL;DR: The aim of this paper is to review and analyze the current knowledge on ageing process and on its effect on the long term performance of implants in order to distinguish between scientific facts and speculation.
