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:

State of the art of zirconia for dental applications
Isabelle Denry,J. Robert Kelly +1 more
TL;DR: The two main processing techniques, soft and hard machining, are assessed in the light of their possible clinical implications and consequences on the long-term performance of zirconia.
Journal ArticleDOI
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.

Microstructural and Chemical Influences of Silicate Grain-Boundary Phases in Yttria-Stabilized Zirconia
TL;DR: The microstructure and chemistry of grain-boundary phases in silicate-doped Y{sub 2}O{sub 3}-ZrO(sub 2) ceramics were evaluated by analytical electron microscopy.

Friction and wear of ultrahigh molecular weight polyethylene against various new ceramics
A.Ben Abdallah,Daniel Treheux +1 more
TL;DR: In this article, the friction and wear behavior of polyethylene against new ceramic materials has been investigated and it has been shown that wear particles are transferred from polymethylene to the ceramic counterface during the wear test.
Journal ArticleDOI
Mechanical Properties and Existing Phases of Composite Ceramics Obtained by Sintering of a Mixture of Hydroxyapatite and Zirconia
TL;DR: The following two thermal transformations were observed in the present system: decomposition of hydroxyapatite to α-tricalcium phosphate and transition of tetragonal zirconia to cubic phase.
Journal ArticleDOI
Forming and sintering of multiphase bioceramics
TL;DR: In this paper, a novel procedure for multiphase powders using wet pretreatment and direct forming of green bodies having the desired geometries was studied, where the forming of discs and femoral heads was done by pressure casting of aqueous suspensions of powders.

Risks and advantages in standardization of bores and cones for heads in modular hip prostheses.
B. Cales,Y. Stefani +1 more
TL;DR: The main taper parameters that directly influence the performance of ceramic head-metallic trunnion assemblies are discussed and it is argued for standardization that integrates all these parameters.
