Ti based biomaterials, the ultimate choice for orthopaedic implants – A review
TL;DR: In this paper, the influence of alloy chemistry, thermomechanical processing and surface condition on these properties is discussed and various surface modification techniques to achieve superior biocompatibility, higher wear and corrosion resistance.
Journal ArticleDOI
On the mechanisms of biocompatibility.
TL;DR: It is shown that, in the vast majority of circumstances, the sole requirement for biocompatibility in a medical device intended for long-term contact with the tissues of the human body is that the material shall do no harm to those tissues, achieved through chemical and biological inertness.

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
Stabilized Zirconia As A Structural Ceramic: An Overview
J. Robert Kelly,Isabelle Denry +1 more
TL;DR: This review introduces concepts and background from the ceramics engineering literature regarding metastable zirconia ceramic to establish a context for understanding current and emerging zIRconia-based dental ceramic technology.

Low‐Temperature Aging of Y‐TZP Ceramics
TL;DR: In this article, the isothermal tetragonal-to-monoclinic transformation of a 3Y-TZP ceramic was investigated from 70° to 130°C in water and in steam by X-ray diffraction and optical interferometer techniques.
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.
Journal ArticleDOI
Environmental degradation of zirconia ceramics
TL;DR: In this article, a review of the existing published experimental evidence for ageing mechanisms in zirconia ceramics is presented and discussed and attention is drawn to the contradictions between the theories.
Journal ArticleDOI
Critical effect of cubic phase on aging in 3 mol% yttria-stabilized zirconia ceramics for hip replacement prosthesis
TL;DR: In this paper, the isothermal tetragonal-to-monoclinic transformation of 3Y-TZP ceramics sintered at two different temperatures and duration (2 and 5h) was investigated at 134°C in steam.
Journal ArticleDOI
Influence of surface finish and residual stresses on the ageing sensitivity of biomedical grade zirconia
TL;DR: The results demonstrate that roughness alone cannot be used for ensuring a long-term stability of biomedical grade zirconia, and the variation of ageing sensitivity is indeed related indirectly to the surface roughness via the induced surface stress state.
