Hybrid Plasma Activation Strategy for the Protein‐Coated Magnesium Implants in Orthopedic Applications (Adv. Mater. Interfaces 9/2022)

Biocompatibility of magnesium-zinc alloy in biodegradable orthopedic implants.

In this study, magnesium-zinc (Mg-Zn) alloy was investigated as a biodegradable orthopedic implant. MC3T3-E1 cell attachment, mineralization and osteogenic-specific mRNA expression were assessed for as measurements of the in vitro biocompatibility of Mg-Zn alloy. In vivo degradation of the Mg-Zn alloy and the accompanying new bone formation in the femoral marrow cavity were analyzed by scanning...

Rapid Manufacturing of Co-Cr-Mo Implants by Three-Dimentional Printing Process for Orthopedic Applications

     The fabrication of complex-shaped parts out of (wt %) Co-28Cr-6Mo alloy by three-dimensional printing (3DP) was studied using two grades of the alloy with average particle sizes of 20 and 75 μm. To produce sound specimens, 3DP processing parameters were tuned. The sintering behavior of the powders was characterized by the dilatometric analysis. Batch sintering in argon atmosphere at 1280 °...

Cellular response of chondrocytes to magnesium alloys for orthopedic applications

In the present study, the effects of Mg-Nd-Zn-Zr (JDBM), brushite (CaHPO4·2H2O)-coated JDBM (C-JDBM), AZ31, WE43, pure magnesium (Mg) and Ti alloy (TC4) on rabbit chondrocytes were investigated in vitro. Adhesion experiments revealed the satisfactory morphology of chondrocytes on the surface of all samples. An indirect cytotoxicity test using MTT assay revealed that C‑JDBM and TC4 exhibited res...

Fabrication of Drug Eluting Ti Implants for Dental/orthopedic Applications

Titanium and its alloys are typically used for fabrication of dental and orthopedic implants as they posses various desirable properties including biocompatibility and corrosion resistance. In spite of such benefits, titanium implants show lack of osseointegration after surgery in minor cases. The objective of this research has been to modify the surface of titanium alloy for medical applicatio...
