TLDR
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.About:

An overview of zirconia ceramics: Basic properties and clinical applications
TL;DR: Clinical evaluations, which have been ongoing for 3 years, indicate a good success rate for zirconia FPDs, and newly proposed zIRconia implants seem to have good biological and mechanical properties; further studies are needed to validate their application.
Journal ArticleDOI
Current ceramic materials and systems with clinical recommendations: A systematic review
TL;DR: This article reviews the current literature covering all-ceramic materials and systems, with respect to survival, material properties, marginal and internal fit, cementation and bonding, and color and esthetics, and provides clinical recommendations for their use.

Effect of surface conditioning methods on the bond strength of luting cement to ceramics
Mutlu Özcan,Pekka K. Vallittu +1 more
TL;DR: Bond strengths of the luting cement tested on the dental ceramics following surface conditioning methods varied in accordance with the ceramic types, and hydrofluoric acid gel was effective mostly on the ceramic having glassy matrix in their structures.
Journal ArticleDOI
Crack growth resistance of alumina, zirconia and zirconia toughened alumina ceramics for joint prostheses.
TL;DR: A new generation of alumina-zirconia nano-composites having a high resistance to crack propagation, and as a consequence may offer the option to improve lifetime and reliability of ceramic joint prostheses.

Degradation During Aging of Transformation‐Toughened ZrO2‐Y2O3 Materials at 250°C
TL;DR: In this article, the detrimental aging phenomenon observed in ZrO2-Y2O3 materials was investigated with respect to the gaseous aging environment and the Y 2O3 and SiO2 content of the material and it was shown that the aging phenomenon is caused by water vapor and that intergranular silicate glassy phases play no significant role.

Role of H2O on the degradation process of Y-TZP
TL;DR: Yttrium-doped tetragonal zirconia (Y-TZP) is expected to be a good structural ceramic material because of its high strength, high toughness and wear resistance, but the instability of this material during ageing is a severe problem which must be solved.
Journal ArticleDOI
Tissue compatibility and stability of a new zirconia ceramic in vivo.
TL;DR: The result suggests that zirconia ceramic is biocompatible and no degradation of zirConia ceramic occurred.

Structure and Thermomechanical Properties of Partially Stabilized Zirconia in the CaO-ZrO2 System
TL;DR: Partially stabilized zirconia (PSZ) ceramics in the system CaO-ZrO2 were characterized by optical microscopy as mentioned in this paper, which revealed that the microstructure provided an effective stress-relieving mechanism during thermal shock.
