Thus, metallic implants based on Ti (Ti6Al4V), Co-Cr alloys, and stainless steel (SS316L) have been used for more than a decade by clinicians for orthopedic reconstruction. However, a strong mismatch between the elastic moduli and tensile strengths of these metals and natural bone causes stress shielding effects resulting in the weakening and consequent fracture of the surrounding bone.

Cardiovascular implants seem to be a bit ahead of orthopedic implants in this respect. If and to what extent magnesium implants will become common practice still remains to be seen. At the time of writing of this editorial, an early generation of magnesium drug-eluting coronary stents is …
In addition, the societal and economical impacts of developing biodegradable orthopedic implants have been emphasized. DOI 10.3390/ma5010135 ISSN 1996-1944 Citation Salahshoor M, Guo Y. Biodegradable Orthopedic Magnesium-Calcium (MgCa) Alloys
orthopedic implants [1,2] and cardiovascular stents [3,4].TheWE43 magnesium alloy is one of the attractive biomedical rare-earth magne-sium alloys without potentially toxic aluminum [5,6] and addition of ical properties and corrosion resistance of magnesium
2020/8/11· Magnesium, a biocompatible and naturally occurring metal in the human body, is a seemingly perfect choice of material for biodegradable implants, except …
Further, the microstructure and composition of the base alloy played a key role on the growth and degradation mechanisms of the MgF 2 coatings. The aim of the present work was the synthesis of biodegradable MgF2 coatings by chemical conversion on the commercial Elektron 21 and AZ91D magnesium alloys, in aqueous HF solutions for different concentrations and temperatures.
Most conventional orthopedic implants used for repairing joint and bone fractures consist of metallic biomaterials with polycrystalline etc., caused by deformation processing. For example, the corrosion resistance in 3.5 % NaCl of AZ31B magnesium alloy has
beneficial for orthopedic appliions.5,6 But magne-sium-based implants used to have high corrosion rates accompanied with hydrogen gas production.2 The present study investigated the local and systemic effects of a magnesium-based screw, which is made
2.3. Magnesium-Based Alloy Design Although magnesium is biocompatible, increased degradation rates under physiological pH conditions can locally reduce the biocompatibility on the implant surface. Efforts to control the implants.

2012/2/6· And as early as 1907, a magnesium alloy was used by Laotte, to secure a bone fracture in the lower leg[20, 21]. Metallic implants are generally used in load bearing appliions where their high mechanical strength and fracture toughness make’s them superior to ceramics, polymeric materials and polymer / ceramic composites.
Although titanium-based implants are widely used in orthopedic and dental clinics, improved osseointegration at the bone–implant interface is still required. In this study, we developed a titanium alloy (Ti-6Al-4V, Ti) coated with epigalloechin gallate (EGCG) and magnesium ions (Mg2+) in a metal-polypheno
