Abstract Reconciling the dilemma between rapid degradation and overdose toxicity is challenging in biodegradable materials when shifting from bulk to porous materials. Here, we achieve significant bone ingrowth into Zn-based scaffolds with 90% porosity via osteoinmunomodulation. At microscale, an alloy incorporating 0.8 wt% Li employed create a eutectoid lamellar structure featuring LiZn 4 Zn phases. This microstructure optimally balances high strength immunomodulation effects. mesoscale,...
Recently, zinc (Zn) and its alloys have demonstrated great potential as guided bone regeneration (GBR) membranes to treat the problems of insufficient alveolar volume long-term osseointegration instability during dental implantology. However, is a complex process consisting osteogenesis, angiogenesis, antibacterial function. For now, in vivo osteogenic performance activity pure Zn are inadequate, thus fabricating platform endow with multifunctions may be essential address these issues. In...
Magnesium alloys with integration of degradability and good mechanical performance are desired for orthopedic implants. In this paper, Mg-2Sr-Ca Mg-2Sr-Zn were prepared the degradation as well bone response investigated. Compared binary Mg-2Sr alloys, addition Ca Zn improved in vitro vivo corrosion resistance. exhibited more uniform maintained configuration implants 4 weeks post-implantation. The rates 0.85 mm/yr 1.10 comparison 1.37 Mg-2Sr. cell tests indicated that higher MG63 viability...
The electrochemical behavior of potential orthopedic Mg-Ca, AZ31 and AZ91 alloys was studied in Hank's solution, Dulbecco's Modified Eagle's Medium (DMEM) serum-containing medium (DMEM adding 10% fetal bovine serum (DMEM+FBS)) over a 7 day immersion period. biocorrosion the above three for various time intervals investigated by linear polarization impedance spectroscopy (EIS). After immersion, potentiodynamic tests were carried out surface morphologies experimental samples examined scanning...
The surface morphologies before and after immersion corrosion test of various chitosan-coated Mg-1Ca alloy samples were studied to investigate the effect chitosan dip coating on slowdown biocorrosion. It showed that resistance Mg-Ca increased with chitosan, depended both molecular weight layer numbers coating. coated by a 2.7 x 10(5) for six layers has smooth intact morphology, exhibits highest in simulated body fluid.
Poly(l-lactic acid) (PLLA) and magnesium (Mg) are widely concerned biodegradable materials, but during in vivo implantation, the former produces acidic degradation byproducts can easily induce inflammation surrounding tissues, whereas latter is fast corroded generates alkaline products. The purpose of this study to develop Mg/PLLA composite microspheres as a novel delivery system, which Mg particles used regulate drug release profile suppress PLLA-induced inflammatory response. Morphological...
Compared to biodegradable Mg-based and Fe-based alloys, Zn-based alloys offer distinct advantages as orthopedic internal fixation implants due their tunable mechanical strength, moderate corrosion rate, pleasant cytocompatibility, dose-dependent osteoinductivity, intrinsic bacteriostatic activity. Therefore, recent attention has been paid on the design, fabrication, clinical translation of alloys. The purpose this research was briefly discuss feasibility, challenges, future prospects...
Abstract In this article, a novel MgCa alloy‐hydroxyapatite‐tricalcium phosphate (HA/TCP) composite was fabricated using the liquid alloy infiltration technique. The feasibility of for biomedical applications studied through mechanical testing, electrochemical immersion and cell culture evaluation. It shown that had strength about 200‐fold higher than original porous HA/TCP scaffold but retained half bulk alloy. corrosion test indicated resulting exhibited an average rate 0.029 mL cm −2 h −1...
