Biocompatibility and biodegradation studies of a commercial zinc alloy for temporary mini-implant applications

Open access

Abstract

In this study, the biocompatibility and in vitro degradation behaviour of a commercial zinc-based alloy (Zn-5 Al-4 Mg) were evaluated and compared with that of pure zinc for temporary orthopaedic implant applications. Biocompatibility tests were conducted using human alveolar lung epithelial cells (A549), which showed that the zinc alloy exhibits similar biocompatibility as compared to pure zinc. In vitro degradation evaluation was performed using weight loss and electrochemical methods in simulated body fluid (SBF) at 37 °C. Weight loss measurements revealed that the degradation of the zinc alloy was slightly lower during the initial immersion period (1-3 days), but marginally increased after 5 and 7 days immersion as compared to pure zinc. Potentiodynamic polarisation experiments showed that the zinc alloy exhibits higher degradation rate than pure zinc. However, electrochemical impedance spectroscopy analysis suggests that pure zinc is susceptible to localized degradation, whereas the zinc alloy exhibited passivation behaviour. Post-degradation analysis revealed localized degradation in both pure zinc and the zinc alloy.

  • Zinc is recognised as an excellent candidate for zinc-based orthopaedic implants due to its biocompatibility and safety.

    “Zinc is now recognised as an excellent candidate for zincbased orthopaedic implants, being chosen for its biocompatibility and safety (30,34).”

    From Zinc as a non-hormonal contraceptive: a better alternative to the copper intrauterine device (IUD) (2022) · cites this paper as [30]

    The Introduction describes metallic zinc as a potential biodegradable, biocompatible material for temporary orthopaedic mini-implants and discusses evidence relevant to safety. But it also says research on zinc implants is limited and notes possible cytotoxicity and localized degradation. The paper supports zinc's promise, not an unqualified claim that it is recognised as an excellent, safe implant candidate. (LLM, conf=0.83)

    Experimental — accuracy not yet measured
  • The present findings, with emerging use of zinc in biocompatible implants, provide a positive indication of the potential biocompatibility of a ZnIUD.

    “Although there have been significantly fewer studies conducted on the interaction of zinc in the uterus compared to those of copper, the present findings, in conjunction with the emerging use of zinc in biocompatible implants provides a positive indication of the potential biocompatibility of a ZnIUD (29,30).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
