Tribocorrosion of total hip replacements [PDF]

, 2012
The performance of metal-on-metal total hip replacements is largely determined by their propensity to degrade in vivo. Degradation occurs through the complex interactions between wear and corrosion (termed tribocorrosion) and leads to the production of ...

Corrosion, wear, and tribocorrosion behavior of a novel biomedical implant Ti-20Zr-10Nb-4Ta alloy

Next Materials
For a new type biomedical titanium alloy, the tribocorrosion should be investigated. So, in this paper, the tribocorrosion behavior of the Ti-20Zr-10Nb-4Ta alloy in Hank’s solution was investigated, and the corrosion and wear behaviors were also ...

Emerging risk factors influencing the occurrence of peri‐implantitis

Periodontology 2000, EarlyView.
Abstract Background The objective of the present review is to explore the evidence and biological plausibility of factors that may expose dental implants to a greater likelihood of developing peri‐implantitis. Material and Methods An electronic screening on the PubMed library the was carried out to identify potential emerging factors that influence the

Tribocorrosion Behavior Of Biofunctional Titanium Oxide Films Produced By Micro-arc Oxidation: Synergism And Mechanisms.

, 2016
Dental implants, inserted into the oral cavity, are subjected to a synergistic interaction of wear and corrosion (tribocorrosion), which may lead to implant failures.

Population level data on aging in periodontal and peri‐implant health—Aging is not a contraindication for periodontal or peri‐implant therapy

Periodontology 2000, EarlyView.
Abstract Objectives Global population aging is leading to a greater retention of natural teeth into later life and an increasing prevalence of dental implant therapy. Although advanced age has traditionally been regarded as a risk factor for compromised outcomes, population level evidence remains lacking.

Tribocorrosion performance of additively manufactured CuNi30 and SS-316L in marine environment: Seawater resistant alloys

Journal of Materials Research and Technology
This study presents the first systematic investigation of the tribocorrosion resistance of additively manufactured CuNi30 in artificial seawater (ASTM D1141-98), along with mechanical and tribocorrosion performance comparison against SS-316L. Both alloys

Improved Tribocorrosion Resistance of a CoCrMo Implant Material by Carburising

Lubricants, 2018
Tribocorrosion damage is a cause for the premature failure of hip implants made of cobalt-based alloys. Low-temperature carburising can be a plausible solution towards mitigating the tribocorrosion damage of articulating components.

Decoding host–microbial dynamics in peri‐implantitis: Ecosystem‐specific experimental models

Periodontology 2000, EarlyView.
Abstract Background Peri‐implantitis is an inflammatory disease arising within a unique host–microbial–biomaterial ecosystem. Unlike periodontitis, peri‐implant tissues lack a periodontal ligament and epithelial junction integrity and interface with metal oxides on titanium surfaces.
